Abstract
A method and apparatus for treating tinnitus involves generating a noise signal to mask the ringing or buzzing in the ears caused by tinnitus and transposing the noise signal into the ultrasonic frequency range. As such, the masking signal effectively masks the tinnitus noise without interfering with the subject's perception of normal sounds such as human speech. In an alternative embodiment, human speech is transduced into electrical signals, transposed to the ultrasonic frequency range, and physically applied to the patient while tinnitus masking signals in the auditory range are applied to the patient.
Claims12
Apparatus for treating a patient for symptoms caused by tinnitus, comprising:
- means for generating a masking noise signal in an ultrasonic frequency range;
- and
- an electric/vibratory transducer for applying said masking noise signal physically to a selected body part of said patient to alleviate said symptoms caused by tinnitus.
Apparatus for treating a patient for symptoms caused by tinnitus, comprising:
- means for generating a masking noise signal in an ultrasonic frequency range;
- and
- means for applying said masking noise signal physically to a selected body part of said patient to alleviate said symptoms caused by tinnitus;
- wherein said generating means comprises a noise signal generator which generates an auditory masking noise signal in an auditory frequency range, and an ultrasonic modulator for transposing said auditory masking noise signal to said ultrasonic frequency range.
Apparatus for treating a patient for symptoms of tinnitus, comprising:
- means for generating a masking noise signal in an auditory frequency range;
- means for applying said masking noise signal to a selected body part of said patient to alleviate said symptoms of tinnitus;
- transducer means for converting sounds in an auditory frequency range into audio frequency electrical signals;
- ultrasonic modulator means for converting said audio frequency electrical signals into ultrasonic frequency electrical signals;
- and
- means for applying said ultrasonic frequency electrical signals physically to a selected body part of said patient.
A method for treating a patient for symptoms of tinnitus, comprising the steps of:
- generating a masking noise signal in an ultrasonic frequency range;
- converting said masking noise signal into a vibratory signal;
- and
- applying said vibratory signal to a selected body part of said patient to alleviate said symptoms of tinnitus.
Apparatus for treating a patient for symptoms caused by tinnitus, comprising:
- a noise signal generator for generating a masking noise signal in an ultrasonic frequency range;
