Processing and Analysis of Bioacoustic Signals

Bioacoustic signals refer to sound signals generated, transmitted and received by organisms (animals or plants), covering the information exchange and sensing between organisms and the environment through sound waves. These signals can be transmitted through gas, liquid or solid media and are widely present in various ecosystems.

Bioacoustic modeling and simulation simulates the generation, transmission, reception and decoding process of bioacoustic signals through mathematical models, computer algorithms and acoustic theories. This technology can not only accurately reproduce the vocalization and hearing mechanisms of organisms, but also be used to predict and analyze complex bioacoustic phenomena.
