Bioacoustics

Spectrograms of Thrush nightingale (Luscinia luscinia) and Common nightingale (Luscinia megarhynchos) singing help to reliably distinguish these two species by voice.

Bioacoustics is a cross-disciplinary science that combines biology and acoustics. Usually it refers to the investigation of sound production, dispersion and reception in animals (including humans).[1] This involves neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the medium they disperse through. The findings provide clues about the evolution of acoustic mechanisms, and from that, the evolution of animals that employ them.

In underwater acoustics and fisheries acoustics the term is also used to mean the effect of plants and animals on sound propagated underwater, usually in reference to the use of sonar technology for biomass estimation.[2][3] The study of substrate-borne vibrations used by animals is considered by some a distinct field called biotremology.[4]
