Bioacoustics

Definition

Bioacoustics is the study of sound production, dispersion, and reception in animals, including humans. This field examines how various species use sound for communication, navigation, and survival, and it has historical significance in understanding the interactions between organisms and their environments. The development of bioacoustics has evolved through technological advancements and interdisciplinary research, influencing various fields such as ecology, wildlife conservation, and even human health.
