Sound enrichment for the relief of tinnitus
First Claim
1. A sound enrichment system for provision of tinnitus relief, the sound enrichment system comprising:
- a noise generator;
at least one signal modulator configured to perform an adjustment of a noise signal to obtain an adjusted noise signal, wherein the at least one signal modulator is configured to perform the adjustment of the noise signal at a rate that is slower than a rate of amplitude variation in the noise signal by a factor of at least ten, the noise signal obtained using the noise generator;
an output transducer for conversion of the adjusted noise signal to an acoustic signal for presentation to a user; and
a microphone;
wherein the output transducer and the microphone are parts of a hearing aid.

Abstract
A sound enrichment system for provision of tinnitus relief, the sound enrichment system includes a noise generator, at least one signal modulator for random or pseudo-random modulation of a noise signal that is obtained using the noise generator, and an output transducer for conversion of the modulated noise signal to an acoustic signal for presentation to a user. A method of providing a noise enriched sound signal for provision of relief of tinnitus includes generating a randomly or pseudo-randomly modulated noise signal, generating an acoustic noise signal using the modulated noise signal, and presenting the acoustic noise signal to a tinnitus suffering person.
