摘要: Abstract The cochlear microphonic (CM) is an electrical signal generated inside the cochlea in response to sound. This reflects mechanical activity and excitation processes involved its generation. However, difficulty of obtaining this simplicity other signals such as otoacoustic emissions have discouraged use a tool for studying functions. In article, model presented which integrates both aspects, enabling interaction between them be investigated. resulting then used observe effect amplifier on CM. results indicate that while significantly amplifies basilar membrane displacement, CM less significant. Both these outcomes are consistent with previous physiological findings. Moreover, close match predictions experimental measurements validates model, suggests further investigations using into various pathologies anomalies warranted.
