Acoustic detectability of bats varies according to their emission frequencies and weather (temperature, moisture) but also according to methodological factors such as the quality of the material and gain. In Parallèle, the identification of acoustic sequences specific reliability level is highly variable depending on particular species, quality recordings, the length and nature of the sequences.
