Editing Bioacoustics (section)

===Sound production, detection, and use in animals===
[[Scientist]]s in the field of bioacoustics are interested in anatomy and neurophysiology of [[organ (anatomy)|organs]] involved in sound production and detection, including their shape, [[muscle]] action, and activity of [[neuronal network]]s involved. Of special interest is coding of signals with [[action potential]]s in the latter.

But since the methods used for neurophysiological research are still fairly complex and understanding of relevant processes is incomplete, more trivial methods are also used. Especially useful is observation of behavioural responses to acoustic signals. One such response is [[phonotaxis]] – directional movement towards the signal source. By observing response to well defined signals in a controlled environment, we can gain insight into signal function, [[Stimulus (physiology)|sensitivity]] of the hearing apparatus, [[noise]] filtering capability, etc.
