The invention is a device and method to reduce the internal body sounds interference with Otoacoustic Emissions (OAE) measurements. Input sounds including ambient sounds and stimulus sounds reach the inner ear by utilizing two mechanisms: A) Through the ear canal / eardrum, the ossicles and then the cochlea entering through the oval window. B) Through the temporal bones and through the air next to the cochlea and the cochlear bone. Both mechanisms stimulate the cochlea and are independent of each other. Two types of output sounds are handled: A) Internal body sound e.g. breathing, blood flow friction, etc. These sounds can be measured through the eardrum and through any other bone surface near the ear e.g. the temporal bone. B) OAE response which can only be detected through the middle ear mechanism. The sound generated by the outer hair cells is transmitted through the oval window to the ossicles and then to the eardrum. The stirrup ossicles creates a tight seal for the cochlea which prevents cochlear liquid escaping from the cochlea and allows OAE to use the ossicles as their exclusive emittance path. The invention is based on the phenomenon that OAE is transmitted as output sounds (only) to the eardrum and from there into the ear canal while it is not transmitted as output sounds to the temporal bones. The present invention produces a cleaner OAE response signal by reducing the interference of body sounds when evoking an OAE response of a subject. The obtained cleaner OAE response signal is transmitted to a recorder which enables further processing of the signal(s).Linvention concerne un dispositif et un procédé pour réduire les interférences de sons organiques internes avec des mesures doto-émissions acoustiques (OAE).
