Audiometry device based on cochlear microphonic potentials.

The cochlear microphonic potentials are nano-sized potentials produced in the outer hair cells of the cochlea. This signal has very special properties that might lead to reach an objective audiometry system. However, the research process needed is hard and long. The “Instituto de investigación Sanitaria Gregorio Marañón” (IiSGM) decided to start a collaboration with the company Zero Entropy S.L in order to develop an objective audiometry device based on cochlear microphonic potentials. The first step is to understand what is going on in the hearing physiology and the cochlear microphonic potentials production. Secondly, the understanding of the socio-economic and legal feasibility of the project is needed. Finally, the implementation of a new CMP detecting system has to be tested and its results analyzed.
