  • Tinnitus masker
    Patent number: 4222393
    Abstract: A tinnitus patient is subjected to external sounds of different pitch, one after another, to enable the patient to identify the particular external sound having the same pitch as the subjective tinnitus sound perceived by the patient. Then the patient is provided with a power operated sound generator producing a range of frequencies extending above and below said perceived pitch to mask the tinnitus sound. The sound generator may be worn in the same manner as a hearing aid and may be combined with a hearing aid if necessary.
