**4. Dataset Analysis**

In this section, a detailed analysis of the ANEs present in the labeled WASN-based audio database is described. Specifically, the distribution of the occurrences and duration of the ANE subcategories together with their contextual SNR distribution and the impact of each of them to the *LAeq* value are analyzed. First, an analysis was conducted regarding the general characteristics of the new audio dataset considering the spectral and time behavior of nodes recordings along one day. Secondly, two more detailed analyses were performed: *(i)* aggregating values of occurrence, duration, and SNR, as well as *LAeq* impact considering all network sensors at a whole and, *(ii)* highlighting the particularities of sensor's locations of the WASN in terms of the same ANE statistical measures.
