Round 1
Reviewer 1 Report
Frequency and Time Domain Analysis of EEG based Auditory 2 Evoked Potentials to Detect Binaural Hearing in Noise
Minor revisions are required:
Abstract
The authors do not mention the characteristics of the sample.
Introduction: it is excessively long and deserves an adequate summary to focus attention on the objective of the study
Line 39 A list of causes of hearing loss is not essential for the purpose of the study
Line 49 Why do you only mention conductive hearing loss in this phrase?
Line 118-line 123 Is a repetition.
Line 130-149 this part deserves a summary as there are many repetitions
From line 151 to 200 The length of this section relating to the technical characteristics of the recording distracts the reader and loses interest. specify these characteristics in the methods and summarize a lot in the introduction.
Line 202 is a repetition
Line 205 What is BMLD? you have not used this acronym before in the text; explain.
Line 209 Do not anticipate the results in the introduction but better list the objectives of the study
Materials and Methods
Participants: a detailed list of inclusion and exclusion criteria is missing which makes the study not reproducible
Specify the age range of the subjects included, the mean age and the standard deviation, the male/female ratio.
The hearing threshold of 20 dB HL in all patients seems contrived; calculate the mean PTA and the standard deviation
Auditory Stimuli
How were auditory stimuli sent? headphones? Specify
Results and analysis
I personally do not appreciate the union that has been made between the methods of analysis and the results. I leave the decision to the editor but in my opinion separating the sections facilitates the reading of the article and makes the results clearer to the reader.
Discussion and conclusions
No comment to make; The text turns out to be sufficiently explanatory, concise and pleasant to read compared to the other parts that are more confusing.

Author response & action: Thank you for your valuable comment. We are analysing the results one after another in a continuous manner and with respect to the previous results obtained. Hence, it’s better for us to write both sections together to convey our results and findings to the readers. Also, the separation of section as suggested can affect the entire structure of the current manuscript. We highly appreciate your suggestion and in our future works we will be taking your suggestion on writing into consideration.

Reviewer 2 Report
The work is of great practical and scientific interest. The topic is very relevant, especially considering the annually growing number of patients with hearing loss.
This study is unique in that it focuses on phase changes and uses stimuli with frequency and noise parameters. The findings may improve our understanding of binaural processing in the human brain and lead to applications in the development of new objective hearing tests in the future.
For the first time such an analysis was carried out between by antiphasic and homophasic stimuli in binaural processing in the human brain by auditory evoked potentials (AEPs) and demonstrates brain's ability to detect and process interaural phase differences, crucial for sound source localization and other auditory processing aspects.
The purpose of the study is described clearly.
The rational for selecting that particular statistic, and which variables were entered into the statistic are described.
statistical methods of comparison were chosen very competently.
Statistical results are presented in a Tables and Figures.
Long introduction. However, this is justified due to the explanation of many terms and concepts that may be new to the reader. The introduction discusses the main issues related to the topic, with reference to contemporary sources. The results are presented and demonstrated in an understandable scientific language using comparative and correlation analysis. Results are structured around the Research Questions.
The title of the article matches the content. The purpose and objectives of the work are fully realized.
Based on the results of this study, the authors came up with important findings with the determination of reliable frequency ranges and localization of recording electrodes for registration middle latency responses late latency responses.
Discussion and conclusions follow logically from the results of the study and are fully consistent with the purpose of the study.
The main findings as related to the overall purpose of the study are discussed and explained in detail.
Conclusions is directly related to the data that was collected and analyzed.

Concerns: Make sure that abbreviations of terms and their descriptions are at the beginning of the text.
Author response & action: Thank you for the valuable concern. We have now double checked the issue and now have made sure that all the abbreviations of terms and their descriptions are at the beginning of the text.
