Tuning fork test: Rinne

Part of Lesson Plan: Hearing Tests Using Tuning Forks **

Activity Overview / Details

The Rinne compares the duration of sound perception by air conduction with that of bone conduction.

Tap the fork to set it vibrating and place the stem on the patient's mastoid bone behind the ear. Time this until the patient says he can no longer hear it, then place the fork about 2 cms from the outer ear.  Time this until the patient no longer hears it.

Normal hearing can hear the sound at least twice as long through air  as through bone.  In conductive loss the sound is heard longer by bone than by air.

Students can perform the test.
