reflex decay test

A test used in audiometry to see how the eardrum responds to a loud tone applied either directly to the ear of interest or to the opposite (contralateral) ear. The sonic stimulus makes the stapedius muscle contract. Data from the test help to determine whether abnormal responses to the tone are the result of damage to the acoustic nerve or to the cochlea.
