Acoustic reflex

The acoustic reflex is a natural response of the middle ear muscles that contract when loud sounds are heard. This reflex helps protect the inner ear from potential damage by reducing the intensity of loud noises. It also plays a role in stabilizing hearing sensitivity. During testing, a small sound is played, and sensors detect if the middle ear muscles respond by tightening. The presence, absence, or abnormal response of this reflex can provide valuable information about ear health and auditory nerve function. Overall, it’s a protective and diagnostic mechanism important for hearing health management.
