Acoustical analysis of the auditory system of the cricket Teleogryllus commodus (Walker)

摘要: The basic auditory physiology of crickets, and particularly Teleogryllus commodus (Walker) is examined its behavior simulated by electrical analog networks, beginning from the simplest possible model progressing stages to full system found in real insect. It that attenuation sound trachea plays a crucial role mechanism for directional hearing even tracheal diameter fact appropriate produce desired attenuation. In more complex which it recognized probably responds pressure changes sacs underlying tympana rather than simply tympanic motion, phase shift produced combined effects central septum adjoining cavities leading spiracles also important directionality. final includes both able simulate directionality and, part, frequency selectivity system. appears, however, large measure observed due some form neural transducers themselves simple acoustic components
