Otoacoustic Emissions Testing

This type of test is an objec­tive eval­u­a­tion of the hear­ing organ, the cochlea, and the out­er hair cells with­in it. Sounds are con­duct­ed through the mid­dle ear to the inner ear, stim­u­lat­ing the out­er hair cells which emit a response called an otoa­coustic emis­sion. These mea­sured respons­es pro­vide infor­ma­tion regard­ing hear­ing sensitivity.
