The use of invasive methods to record cochlear microphonic potentials preclude its use in routine clinical diagnosis in humans. We present an instrument and method used to obtain cochlear microphonics recordings using external electrodes in human beings. Biological and technical tests were performed before application. Stimulation with a pure, continuous and defined tone yielded cochlear microphonics that can be interpreted easily. This new method allows human cochlear physiology and pathophysiology to be studied non-invasively.
