Stand 1 to 2 ft from the Stand 1 to 2 ft from the client in a position where client in a position where the client cannot read your the client cannot read your lips. Ask the client to lips. Ask the client to occlude one ear by putting occlude one ear by putting a finger in it.a finger in it.

The client is asked whether The client is asked whether the sound is heard equally in the sound is heard equally in both ears or whether the both ears or whether the sound is louder in one ear.sound is louder in one ear.

Normal FindingsNormal Findings:: Hearing the sound equally in Hearing the sound equally in
