Bioacoustics

The Bioacoustics refers to the research field of animal sounds research. It includes the study of the organs of sound production and their functions, the sound events themselves, and the organs of hearing and their achievements. The Bioacoustics deals both with issues of sound properties and their formation as well as with the computer science and their meaning and effect in the coexistence of animals. Different methods of sound recording and analysis are used. According to features can provide an indication in degrees of relationship and behavioral research on behavior in evolutionary biology.

History

The term bioacoustics, 1942 and introduced in 1946 by Albrecht Faber, established in the 1950s. 1956 was founded during an international conference at the Pennsylvania State University, the International Committee on Biological Acoustics. It should serve to coordinate and create a central archive and exchanges.

According formation in animals

The sound production in animals performed with different body parts.

Insects produce sounds by the frequency of wing beat in flight, by drumming with hard skeletons to the backing or special drum organs. In addition, they produce audible sounds by stridulation, by rubbing parts of their exoskeleton.

Birds have vocal cords, but also produce different sounds, such as the woodpecker drumming with his beak.

Fish drums with the swim bladder by synchronous contractions of the drum muscles.

Amphibians such as frogs and toads can produce sounds in the larynx ( Tracheolarynx ) and have sound reinforcement sound bubbles.

Most air breathing vertebrates use their respiratory system for sound formation, similar to the human phonation.
