Abstract: Systems, methods and apparatuses for auditory system disorder rehabilitation by providing a stimulus to the auditory system of an individual experiencing an auditory disorder, tinnitus, conditions of reduced tolerance of loud sounds, or combinations thereof comprising, for example, a playback device and a method and apparatus for modifying an audio signal. The methods may include allowing a user to select an audio source (for example, a music track or the audio output of a television program) and modifying the audio with a spectral modified signal to create a spectrally modified audio. The spectrally modified audio can then be output by the playback device or other means for listening by the user.

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.

Abstract: A digital playback device and a method and apparatus for modifying a digital audio signal. The method includes allowing a user to select a digital audio track and modifying the digital audio track with a predetermined spectral modification signal to create a spectrally modified digital audio track. The spectrally modified digital audio track can then be retrieved by a user to a digital playback device.
