In auditory system, after the frequencies of sound signals are modulated by the basilar membrane, these sounds of different frequencies are processed by different auditory neurons. Design of the broadband electronic circuits is a critical issue to emulate the auditory neurons, because these emulator circuit processes the sound signal of various frequency without require any update. In this study, it is aimed to compare the response performance of the auditory neuron emulator circuits that are built by several analog devices. In this context, an auditory neuron model, which is defined by adapting the vibrations in a piezoelectric ceramic to the FitzHugh-Nagumo neuron model, is successfully implemented with voltage operational amplifier, operational transconductance amplifiers, current feedback operational amplifiers and field programmable analog arrays. After the notes of a musical composition are coded in a microcontroller, its electrical signal output is applied to the auditory neuron emulator circuits as an external excitation signal. The peaks of the excitation signal applying to the emulator circuits and the firing times of the dynamic responses measuring from the outputs of these analog circuits are recorded simultaneously. Then, time differences between stimulus peaks and neuronal firing responses are determined with the "Dynamic Time Warping" algorithm and the input/output synchronization performances of these analog emulators are compared according to the result of this quantitative measurement.
