Background/Objectives: Early pediatric cochlear implantation positively impacts early language outcomes. The Teenager and Young Adults Cochlear Implant (TAYACI) study investigates the long-term outcomes of early implantation and factors influencing variability among cochlear implant (CI) users. This article outlines participants’ background, early language outcomes, and multidisciplinary study protocol. Methods and Materials: Individuals aged 12–22 received CIs before 30 months of age, followed-up at the same hearing implant center, and adhered to a standard school curriculum were invited to participate. Out of 109 eligible CI users, 50 participated; 46 agreed to undergo clinical assessments, while four completed questionnaires only. Results: The mean age at the first CI was 15.63 months (SD = 6.0). All but one communicated with spoken language(s). Participants attended mainstream schools and had highly educated parents. Over half (56%) had received Auditory Verbal Therapy in early childhood. Earlier implantation correlated with better language understanding one year post-CI. Conclusions: Earlier implantation was associated with better early language outcomes, with parental education level and early family-centered intervention likely contributing. Future sub-studies will investigate multidisciplinary long-term effects of pediatric cochlear implantation in adolescents. Full article

Background/Objectives: Vestibular agnosia is characterized by a reduced or absent self-motion perception while demonstrating the presence of normal peripheral vestibular function following stimulation. This condition has previously been reported by previous authors in different populations and more recently in traumatic brain injury patients. However, the underlying mechanisms responsible for vestibular agnosia remain a matter of debate. The objective of this manuscript is to review and compare the behavioral and neuroanatomical findings in populations where vestibular agnosia has been demonstrated to better understand the underlying mechanism. Methods: A review of the literature was conducted using four databases: Medline, Embase, Google Scholar, and PubMed. A normal vestibulo-ocular reflex function with an impaired self-motion perception following vestibular stimulation represented the inclusion criteria used. Results: Behavioral data reviewed in the studies revealed a clear association with postural instability. However, no consensus can be drawn from neuroanatomical data due to variability in brain impairments in those populations even though impairments in the parietal cortex are often reported. Conclusions: In general, behavioral data and neuroanatomical data regarding vestibular agnosia have been poorly documented throughout the literature. However, vestibular agnosia can be observed in different populations and is present in concomitant postural control deficits, an important predictor of falls. Finally, even though the parietal cortex has been associated with vestibular agnosia, future studies are required to adequately identify the underlying mechanism. Indeed, the parietal cortex could be part of a larger network mediating vestibular agnosia. This review proposes various methods that future studies should use to overcome the present limitations.

Background/Objectives: Voice artificial intelligence (AI) technology is becoming increasingly common. Recent work indicates that middle-aged to older adults are less able to identify modern AI speech compared to younger adults, but the underlying causes are unclear. Methods: The current study with younger and middle-aged to older adults investigated factors that could explain the age-related reduction in AI speech identification. Experiment 1 investigated whether high-frequency information in speech—to which middle-aged to older adults often have less access due sensitivity loss at high frequencies—contributes to age-group differences. Experiment 2 investigated whether an age-related reduction in the ability to process prosodic information in speech predicts the reduction in AI speech identification. Results: Results for Experiment 1 show that middle-aged to older adults are less able to identify AI speech for both full-bandwidth speech and speech for which information above 4 kHz is removed, making the contribution of high-frequency hearing loss unlikely. Experiment 2 shows that the ability to identify AI speech is greater in individuals who also show a greater ability to identify emotions from prosodic speech information, after accounting for hearing function and self-rated experience with voice-AI systems. Conclusions: The current results suggest that the ability to identify AI speech is related to the accurate processing of prosodic information. Full article

Background/Objectives: Advances in cochlear implant (CI) technology have led to the expansion of the implantation criteria. As a result, more CI candidates may have greater residual hearing in one or two ears. Many of these candidates will perform better with a CI in one ear and a hearing aid (HA) in the other ear, the so-called bimodal solution. The bimodal solution often requires patients to switch to HAs that are compatible with the CI. However, this can be a challenging decision, not least because it remains unclear whether this impacts hearing performance. Our aim is to determine whether speech perception in noise remains unchanged or improves with new replacement HAs compared to original HAs in CI candidates with residual hearing. Methods: Fifty bilateral HA users (mean age 63.4; range 23–82) referred for CI were recruited. All participants received new replacement HAs. The new HAs were optimally fitted and verified using Real Ear Measurement (REM). Participants were tested with the Hearing in Noise Test (HINT), which aimed at determining the signal-to-noise ratio (SNR) required for a 70% correct word recognition score at a speech sound pressure level (SPL) of 65 dB. HINT testing was performed with both their original and new replacement HAs. During HINT, pupillometry was used to control for task engagement. Results: Replacing the original HAs with new replacement HAs after one month was not statistically significant with a mean change of SRT70 by −1.90 (95% CI: −4.69;0.89, p = 0.182) dB SNR. Conclusions: New replacement HAs do not impact speech perception scores in CI candidates prior to the decision of cochlear implantation. Full article

Background/Objectives: Localization deficit is often said to be a symptom of Auditory Processing Disorder (APD). However, no clinically viable assessment of localization ability has been developed to date. The current study presents pilot data for a new assessment of absolute auditory localization using headphones. Methods: Speech phrases encoded with non-individualized head-related transfer functions (HRTF) using real-time digital processing were presented to two cohorts of participants with normal hearing. Variations in the simulated environment (anechoic and reverberant) and signal to noise ratio (SNR) were made to assess each of these factors’ influences on localization performance. Experiment 1 assessed 30 young adults aged 21–33 years old and Experiment 2 assessed 28 young adults aged 21–29 years old. All participants had hearing thresholds better than 20 dB HL. Results: Participants performed the localization task with a moderate degree of accuracy (Experiment 1: Mean RMS error = 25.9°; Experiment 2: Mean RMS error 27.2°). Front–back errors (FBEs) were evident, contributing to an average RMS error that was notably elevated when compared to similar free-field tasks. There was no statistically significant influence from the simulated environment or SNR on performance. Conclusions: An exploration of test viability in the pediatric and APD-positive populations is warranted alongside further correction for FBEs; however, the potential for future clinical implementation of this measure of absolute auditory localization is encouraging.

Objectives: This study aimed to adapt and validate the Parents’ Evaluation of Aural/Oral Performance of Children (PEACH) questionnaire for Greek-speaking children aged 1 to 6 years. Key objectives included assessing the PEACH questionnaire’s reliability and validity and determining if children from Greece and Cyprus exhibit similar auditory performance, which would suggest they belong to a comparable population. Methods: This cross-sectional study involved 87 children from monolingual Greek-speaking households in Greece (N = 38) and Cyprus (N = 49), all full-term with typical hearing and no cognitive or language deficits. The children’s ages ranged from 12 to 82 months. The study used an independent samples t-test to compare PEACH Overall Scores between Greek and Greek–Cypriot children. Internal consistency was assessed with Cronbach’s alpha and item-total correlations for each country. Additionally, regression models examined the relationship between PEACH scores and age. Results: Greek–Cypriot children had significantly higher PEACH scores (92.09%) than Greek children (86.71%), t(85) = 2.31, p = 0.023. The Cronbach’s alpha for the Greek sample was 0.92, indicating a strong internal consistency, while the Greek–Cypriot sample had a lower alpha of 0.79, with item-total correlations ranging from 0.16 to 0.75. Normative curves showed that auditory performance in the Greek sample increased sharply until 40 months, then plateaued until 60 months. In contrast, the Greek–Cypriot sample’s scores rose sharply until 25 months and plateaued by 40 months. Conclusions: The Greek-translated PEACH questionnaire demonstrated strong reliability and construct validity for Greek children, consistent with other language adaptations. However, the Greek–Cypriot sample did not achieve similar reliability, and differences in scores suggest potential cultural, linguistic, or environmental factors impacting auditory development. These findings emphasize the importance of regional adaptations in standardized assessments. Further research is recommended to explore factors contributing to these differences for more accurate assessments of Greek-speaking children. Full article

Background/Objectives: Globally, many countries have endorsed the World Health Organisation’s (WHO) early intervention (EI) guidelines through their legislation with contextual variations. Sensitive evaluation of gaps within EI-recommended systems is essential, especially in the translation of policy into practice across high-income and low- to middle-income country (LMIC) contexts, including South Africa. The main objective was to explore and identify the current evidence reflecting the application of hearing-specific government policy regarding EI and early education (EE) for hearing-impaired/d/Deaf/hard-of-hearing (HI/D/HH) children aged six and below. Method: An integrative review was conducted on peer-reviewed articles that examined policy in practice regarding EI for HI/D/HH children aged six and below. Studies were accessed via four databases (Ebscohost, Sabinet, Scopus, and ScienceDirect) and one search engine (Google Scholar) between 2014 and 2024. Qualitative evaluation ensued of themes identified deductively. Results: Twenty-six peer-reviewed studies were included. Deductive thematic analysis revealed six derived themes: EI timing, early hearing detection and intervention (EHDI)/EI mechanisms; EI services, EE, family considerations, and policy. Five of the 26 directly scrutinised government policy in its EI/EE practical application. Articles reflected the need for consideration of the complex processes that allow for policy actualisation, such as adequate infrastructure and family considerations. Conclusions: A bottom-up approach to policy actualisation, with grass-roots contextual considerations such as EI access and caregiver concerns, may improve policy application. Current findings have implications, particularly for LMIC contexts including South Africa, where EI and EE policy scrutiny regarding hearing impairment/deafness specificity is imperative for understanding its application alignment.

Objectives: The objectives of the current study were to validate the LittlEARS^® Early Speech Production Questionnaire (LEESPQ) in Romanian and to evaluate the psychometric properties of the Romanian version of the questionnaire for Romanian children with normal hearing. The LEESPQ was created and tested for the assessment of preverbal and early verbal skills (0–18 months) in children with normal hearing. Methods: The English version of the LittlEARS^® Early Speech Production Questionnaire (LEESPQ) was adapted into Romanian language using a translation/back-translation procedure and validation of the content before applying the questionnaire. The Romanian version was applied to the parents of 232 children with normal hearing, aged between 0 and 18 months. The questionnaire was statistically analyzed to assess its reliability, internal consistency, predictive accuracy, and the influence of gender on children’s scores. Results: Statistical analyses confirmed the LEESPQ’s reliability (α = 0.876) and high predictive accuracy (λ = 0.951). Age correlated strongly with total scores (ρ = 0.67; p < 0.001), supporting the age-dependent progression of speech production milestones. Gender did not significantly affect the scores. Normative curves and minimum expected scores were established for each age group. Conclusions: This study confirmed that the Romanian version of the LEESPQ is a reliable, valid, language-independent instrument, useful in the assessment of language development in children with normal hearing, aged up to 18 months.

Objectives: The gold standard for electrocochleography (ECochG) is using dedicated recording devices for auditory evoked potentials. However, these have a very limited time window for recording. The aim of this study is to evaluate EEG amplifiers for ECochG, in particular for recording cochlear microphonics (CMs) without time restriction. Methods: Three high-resolution EEG amplifiers and different types of electrodes were analyzed and compared with a clinical system for recording auditory evoked potentials. For this, CMs were recorded after stimulation with various stimuli in a dummy and in human subjects. In the latter, recordings were made from the tympanic membrane and, during otosurgical procedures, from the promontory. Our evaluation focused on comparing signal amplifiers and electrode types, considering the signal-to-noise ratio, recording characteristics, and measurement reliability. Results: Using a dummy model, we observed significant differences among devices, electrode types, and stimulus frequencies. These findings were subsequently confirmed in human participant measurements. Nevertheless, EEG amplifiers proved to be feasible for ECochG recordings and offered a recording fidelity comparable to proprietary clinical methods. Importantly, with EEG amplifiers, we were able to record cochlear potentials in response to speech stimuli, revealing a strong correlation (r = 0.78) between recorded signals and the input stimulus. Conclusions: Our findings indicate that high resolution EEG amplifiers are suitable for recording cochlear potentials, in particular, CMs. This allows for evaluating cochlear signals in response to extended stimuli, in particular, speech stimuli.

Background: When speaking while wearing a face mask, sound transmission is attenuated, and visual cues are lost due to the covered facial movements of the speaker. In this study, we investigated the extent to which different face masks alter speech intelligibility in individuals with different degrees of hearing impairment. Methods: A total of fifty participants were divided into four hearing status groups according to the degree of hearing loss: normal levels (16), mild (13), moderate (11), and severe (10). A modified version of the Audiovisual German Matrix Sentence Test (AV-OLSA) was used to assess speech perception in noise in five conditions (audiovisual, audio-only, visual-only, surgical mask, and FFP2 mask). Results: Our results show that acoustic attenuations of face masks cause a small but similar decrease in speech reception thresholds (SRTs) in listeners of different hearing statuses. The effect of visual cues (visual benefit) on SRTs was stronger than the effect of acoustic attenuation but also did not differ significantly between the different hearing status groups, with a median difference of 1.5 dB for mild hearing loss, 2.9 dB for moderate hearing loss, and 2.7 dB for severe hearing loss. The best-aided hearing status did not correlate with visual benefit. Conclusions: Our research confirms the importance of providing visual cues for speech reception in noisy environments, especially for individuals with impaired hearing, regardless of their degree of hearing loss.

Aim: The aim of this study was to assess the subjective experiences of adults with different cochlear implant (CI) configurations—unilateral cochlear implant (UCI), bilateral cochlear implant (BCI), and bimodal stimulation (BM)—focusing on their perception of speech in quiet and noisy environments, music, environmental sounds, people’s voices and tinnitus. Methods: A cross-sectional survey of 130 adults who had undergone UCI, BCI, or BM was conducted. Participants completed a six-item online questionnaire, assessing difficulty levels and psychological impact across auditory domains, with responses measured on a 10-point scale. Statistical analyses were performed to compare the subjective experiences of the three groups. Results: Patients reported that understanding speech in noise and tinnitus perception were their main concerns. BCI users experienced fewer difficulties with understanding speech in both quiet (p < 0.001) and noisy (p = 0.008) environments and with perceiving non-vocal sounds (p = 0.038) compared to UCI and BM users; no significant differences were found for music perception (p = 0.099), tinnitus perception (p = 0.397), or voice naturalness (p = 0.157). BCI users also reported less annoyance in quiet (p = 0.004) and noisy (p = 0.047) environments, and in the perception of voices (p = 0.009) and non-vocal sounds (p = 0.019). Tinnitus-related psychological impact showed no significant differences between groups (p = 0.090). Conclusions: Although speech perception in noise and tinnitus remain major problems for CI users, the results of our study suggest that bilateral cochlear implantation offers significant subjective advantages over unilateral implantation and bimodal stimulation in adults, particularly in difficult listening environments.

Background/Objectives: Adults with hearing loss demonstrate poorer overall health outcomes (e.g., physical health, cognitive functioning and wellbeing) and lower levels of physical activity/function compared to those without hearing loss. Hearing aids have the potential to improve cognitive and wellbeing factors, but there is a dearth of evidence on their impact on physical health outcomes. Evidence on the association between hearing aid provision and physical activity is mostly limited to cross-sectional studies. This research aimed to assess whether a study can be performed to identify whether the provision of hearing aids can improve physical activity. Methods: This study employed a preregistered observational (prospective cohort) study design of ten older adults (51–75 years) completed assessments at baseline and again at a six-week follow-up. The participants wore an accelerometer (ActiGraph GT9X) without feedback for the full duration of the study. Feasibility was determined using pre-defined criteria, including study drop-out, adherence to accelerometer use and willingness. A battery of health outcomes was also assessed at baseline and follow-up. Conclusions: Overall, this study was perceived favourably, with all participants reporting that they enjoyed taking part. Participant retention was 100%, and adherence to the wrist-worn accelerometers was “good” (70%). However, recruitment was challenging, and some participants found the accelerometers to be burdensome. Descriptive statistics for all outcome measures showed non-significant changes in the expected direction (e.g., improved physical activity, cognition and wellbeing). Although the study was well received by participants, modifications to the recruitment strategy and activity tracking procedures are necessary before future large-scale trials assessing the effectiveness of hearing aids on physical activity can be undertaken.

Background: Tinnitus is a frequent symptom, and is present in 10–15% of people who suffer from chronic tinnitus, defined as heard every day for at least 6 months. Among these, 1–2% develop a strong emotive reaction, anxiety, and depression, leading to poor quality of life. Objectives: to evaluate the comorbidities in tinnitus sufferers. Methods: In our retrospective study, we collected data on 1156 subjects with tinnitus present for at least 3 months, including age, audiometric exam, THI questionnaire, vascular disorders, fluctuations, causal factors, lifetime psychiatric disorders, and the presence of migraine. A linear regression model was used to assess the independent role of these variables on the THI total score representing tinnitus annoyance. A lifetime history of psychiatric disorders and migraine were predictive for the development of a disabling tinnitus. Results: Among comorbidities a history of previous psychiatric disorders was predictive for developing tinnitus. Moreover, no correlation has been found between hearing level and THI total score. Conclusions: Our data are not inconsistent with the hypothesis that psychological disorders and a particular personality trait may be the main causal factors for tinnitus annoyance. Full article

Peripheral hearing loss is associated with the cross-modal re-organization of the auditory cortex, which can occur in both pre- and post-lingual deaf cases. Background/Objectives: Whether to rely on the visual cues in cases with severe hearing loss with adequate amplification is a matter of debate. So, this study aims to study visual evoked potentials (VEPs) in children with severe or profound HL, whether fitted with HAs or CIs. Methods: This study included three groups of children matched in age and gender: normal hearing, children with hearing thresholds >70 dBHL and fitted with power HAs, and children fitted with CIs. All cases were subjected to pure tone audiometry (aided and unaided), speech discrimination scores, ophthalmic examinations, and visual evoked potentials (VEPs). Results: SD% scores significantly improved with the use of VCs in both CI and HL groups, and a significantly higher P100 amplitude of VEPs in both CI and HL groups (more in children fitted with CIs). Conclusions: Cross-modal reorganization in severe degrees of HL is of great benefit whether they are fitted with HAs or CIs. Full article

Objectives: The present study aims to identify potential predictive factors for developing sensorineural hearing loss (SNHL) in individuals with congenital Cytomegalovirus (cCMV) infection. Methods: A retrospective study was performed on 50 subjects with cCMV infection (symptomatic and asymptomatic), followed at the Audiology Service of Sant’Anna Hospital (University Hospital of Ferrara). The following data were analyzed: the type of maternal Cytomegalovirus (CMV) infection (primary versus non-primary), time of in utero infection, systemic signs and symptoms or laboratory test anomalies due to cCMV infection, and signs and symptoms of central nervous system (CNS) involvement at birth. In particular, brain ultrasonography and encephalic magnetic resonance imaging (MRI) were evaluated, searching for possible links between imaging findings and SNHL. Results: The statistical analysis showed a significantly higher risk of developing SNHL in subjects with signs and symptoms of CNS involvement at birth (p = 0.009 *). The presence of brain MRI abnormalities significantly influenced the onset of SNHL in patients with symptomatic cCMV infection (p = 0.012 *). Brain ultrasonography, the type of maternal CMV infection, systemic signs/symptoms and laboratory test anomalies at birth, and sex resulted in nonsignificant correlations in the analysis. Conclusions: The presence of neurological symptoms at birth and of detectable abnormalities in brain MRI are predictors of SNHL developing in symptomatic cCMV infection. Further investigation on this topic is necessary. Full article

Background: Hearing loss in children can have a detrimental impact on their development, thus lowering the psychological well-being of parents. This study examined the amount of parental stress, learned helplessness, and perceived social support in mothers of children with hearing loss (MCHL) and mothers of typically developing children (MTDC), as well as the relationship between various possible contributing factors to parental stress such as learned helplessness and perceived social support. Method: Three questionnaires measured parental stress (Parental Stress Scale; PSS), learned helplessness (Learned Helplessness Scale; LHS), and perceived social support (Perceived Social Support-Friends PSS-Fr and Perceived Social Support-Family PSS-Fa Scale) in 100 MCHL and 90 MTDC. All mothers had normal hearing and children aged 1 to 12 years. Mothers of children with any degree of bilateral sensorineural hearing loss, using hearing aids and/or cochlear implants, were included in the MCHL group. Children with hearing loss did not have any additional disabilities. Results: Parental stress and learned helplessness were not significantly different between the groups. The perceived social support was significantly lower in MCHL as compared to MTDC. Pearson correlation analysis with pooled data from both groups showed a small but significant negative correlation between parental stress and perceived social support. A moderately significant positive correlation existed between learned helplessness and parental stress. The relationship between learned helplessness and perceived social support was negative, being small but significant. Conclusions: The study findings indicate that parental stress was similar in both groups. As perceived social support increased, parental stress and learned helplessness decreased. Thus, the present study findings indicate the need for developing greater social support for MCHL. Full article

Objectives: to retrospectively evaluate the clinical relevance of the 1000/500 Hz inter-frequency amplitude ratio (IFAR) in cervical and ocular vestibular evoked myogenic potentials (cVEMPs and oVEMPs) in patients with unilateral definite Ménière’s disease (MD) to identify the pathological ear. Method: cVEMPs and oVEMPs results obtained at 500 Hz and 1000 Hz were retrospectively analyzed in 28 patients with unilateral definite MD. 1000/500 Hz IFAR were calculated and compared for each ear. Spearman correlation tests between patient age and 1000/500 Hz IFAR were also performed. Results: No significant difference was observed between the 1000/500 Hz IFAR calculated in both pathological and healthy ears when the cVEMPs were performed (p = 0.74; Wilcoxon signed-rank test). 1000/500 Hz IFAR results obtained in healthy and pathological ears were also not different for oVEMPs (p = 0.73; Wilcoxon signed-rank test). Analysis of modified 1000/500 Hz IFARs for healthy and pathological ears showed no difference in both cVEMPs and oVEMPs (p = 0.44; p = 0.95, respectively; Wilcoxon signed-rank test). There was a significant positive correlation between IFARs, modified IFARs, and patient age for cVEMPs (p = 0.017; p = 0.012, respectively, Spearman’s correlation test). A significant positive correlation was also found between modified IFARs and the subject age in oVEMPs (p = 0.019, Spearman’s correlation test). Conclusions: We did not observe any significant increase of 1000/500 Hz IFARs and 1000/500 Hz modified IFARs in ears affected by definite MD compared to healthy ears. Moreover, our research suggests that the age of the participants may influence IFAR results, which may lead to misdiagnosis in the elderly. It is, therefore, essential to conduct further prospective studies in larger cohorts, stratifying results by participant age, to better understand the role of 1000/500 Hz IFAR values in the diagnosis of MD.

Background/Objectives: Adult hearing-impaired patients qualifying for cochlear implants typically exhibit less than 60% sentence recognition under the best hearing aid conditions, either in quiet or noisy environments, with speech and noise presented through a single speaker. This study examines the influence of deep neural network-based (DNN-based) noise reduction on cochlear implant evaluation. Methods: Speech perception was assessed using AzBio sentences in both quiet and noisy conditions (multi-talker babble) at 5 and 10 dB signal-to-noise ratios (SNRs) through one loudspeaker. Sentence recognition scores were measured for 10 hearing-impaired patients using three hearing aid programs: calm situation, speech in noise, and spheric speech in loud noise (DNN-based noise reduction). Speech perception results were compared to bench analyses comprising the phase inversion technique, employed to predict SNR improvement, and the Hearing-Aid Speech Perception Index (HASPI v2), utilized to predict speech intelligibility. Results: The spheric speech in loud noise program improved speech perception by 20 to 32% points as compared to the calm situation program. Thus, DNN-based noise reduction can improve speech perception in noisy environments, potentially reducing the need for cochlear implants in some cases. The phase inversion method showed a 4–5 dB SNR improvement for the DNN-based noise reduction program compared to the other two programs. HASPI v2 predicted slightly better speech intelligibility than was measured in this study. Conclusions: DNN-based noise reduction might make it difficult for some patients with significant residual hearing to qualify for cochlear implantation, potentially delaying its adoption or eliminating the need for it entirely.

Background: Hearing loss is a highly prevalent condition in the world population that determines emotional, social, and economic costs. In recent years, it has been definitely recognized that the lack of physiological binaural hearing causes alterations in the localization of sounds and reduced speech recognition in noise and reverberation. This study aims to explore the psycho-social profile of adult workers affected by single-sided deafness (SSD), without other major medical conditions and otological symptoms, through comparison to subjects with normal hearing. Methods: This is a cross-sectional, case-control study. Subjects aged between 24 and 65 years, all currently employed and affected by SSD, were enrolled. They were administered both disease-specific and psychometric tests, such as the Hearing Handicap Inventory for Adults (HHIA), the Profile Questionnaire for Rating Communicative Performance, the Psychological General Well-Being Index (PGWBI), and the Social Functioning Questionnaire (SFQ). Results: A total of 149 subjects (mean age = 49.9; SD ± 8.5) were enrolled in the period 2021–2023; 68 were males (45.6%), and 81 were females (54.4%). The normal hearing group was composed of 95 subjects, and the SSD sample was composed of 54 subjects. The results of our study show that the levels of psychological well-being and social functioning in subjects with SSD are statistically worse than in the group of subjects with normal hearing in most subscales. Conclusions: This study definitely outlined evidence for a significantly worse psychological health status and a poorer social attitude of working adults affected by SSD with respect to their normal-hearing counterparts. Understanding the impact of SSD on patients’ work environment suggests a multidisciplinary approach to such patients in order to increase their quality of life through adequate counseling, acceptance, and role modeling.
