EXERCISE EARS TO RESTORE HEARING (May, 1933)

EXERCISE EARS TO RESTORE HEARING

An ear gymnasium, devised by a Michigan inventor, is said to aid those of defective hearing by exercising the nerve centers of the ear. Special earphones are slipped over the patient’s head and at the tone frequencies at which hearing is defective, a series of tone exercises is given at a volume great enough to be heard by the patient. Over a period of time, this is said to improve the hearing.

    … Because nothing improves hearing like prolonged exposure to high-decibel sine waves.
