The sound perceived by the hearing organ of the cricket is translated into the bioelectrical impulses and it travels into the central nervous system, where it is processed by special acoustical nerve cells. One of these is here described AN1 neuron (Ascending Neuron 1), which the processed information transmits further to the subesophageal ganglion.

In the very simplified model of the body of the cricket you see the pair of the front legs bearing the cricket's ears - tympanal organs. Crickets as all insects do not have lungs but use the tracheal system instead. The tracheas are also important in the hearing process since they function as resonators.
