Tinnitus rehabilitation device and method
First Claim
1. A tinnitus rehabilitation method for providing relief to a person suffering from the disturbing effects of tinnitus, the method comprising:
- providing an audio signal including peaks and troughs;
producing a predetermined masking algorithm designed to modify at least one of peaks and troughs of at least a portion of the audio signal at selected frequencies for providing intermittent masking of tinnitus and to account for a basic audiometric configuration of the person; and
spectrally modifying the audio signal in accordance with the predetermined masking algorithm wherein, in use at a comfortable listening level, when the spectrally modified audio signal is heard by the person during the peaks, the tinnitus is substantially completely obscured and the person perceives significant masking of the tinnitus, and during the troughs, the person may occasionally perceive the tinnitus.

Abstract
A tinnitus method and device for providing relief to a person suffering from the disturbing effects of tinnitus is described. The method can be implemented entirely in software to spectrally modify an audio signal in accordance with a predetermined masking algorithm which modifies the intensity of the audio signal at selected frequencies. A predetermined masking algorithm is described which provides intermittent masking of the tinnitus wherein, at a comfortable listening level, during peaks of the audio signal the tinnitus is completely obscured, whereas during troughs the perception of the tinnitus occasionally emerges. In practice it has been found that such intermittent masking provides an immediate sense of relief, control and relaxation for the person, whilst enabling sufficient perception of the tinnitus for habituation and long term treatment to occur. Advantageously the predetermined masking algorithm is specifically tailored to the audiometric configuration of the person. For example, the masking algorithm may be partly tailored to the hearing loss characteristic of the person. A tinnitus rehabilitation device used in conjunction with a personal sound reproducing system is also described.

9. A tinnitus rehabilitation method as defined in claim 1, wherein said spectrally modified audio signal is derived by:
-
transmitting, using a computer, data representing an audiogram of the person suffering from tinnitus;
processing said audiogram data at a remote location and producing required equalisation response data based on said audiogram data using said predetermined masking algorithm;
receiving, using a computer, said required equalisation response data; and
combining said required equalisation response data with audio data representing said audio signal to produce said spectrally modified audio signal.

13. A method of using a computer to provide access to a predetermined masking algorithm used in tinnitus rehabilitation for providing relief to a person suffering from the disturbing effects of tinnitus, the method comprising:
-
receiving on-line, from a user, data representing an audiogram of the person suffering from tinnitus;
processing said audiogram data using said predetermined masking algorithm to produce required equalisation response data based on said audiogram data; and
,transmitting said required equalisation response data to the user for use in the predetermined masking algorithm to provide relief from the tinnitus. - View Dependent Claims (14)
