A tinnitus masking system for use by a person having tinnitus. The system comprises a sound delivery system having left and right ear-level audio delivery devices and is configured to deliver a masking sound to the person via the audio delivery devices such that the masking sound appears to originate from a virtual sound source location that substantially corresponds to the spatial location in 3D auditory space of the source of the tinnitus as perceived by the person. The masking sound being represented by left and right audio signals that are converted to audible sound by the respective audio delivery devices.

A system for psychoacoustic evaluation of tinnitus synthesizes a test sound that is customized for a patient using the patient's audiogram, a model of the tinnitus related to the patient's audiogram, a psychoacoustic loudness model, and various test-sound parameters. In various embodiments, the system automatically adjusts the intensity and spectral level of the test sound such that the intensity of the test sound as perceived by the patient remains approximately constant across various frequencies and/or sound types used in the psychoacoustic evaluation of tinnitus.

A method of generating sounds for reducing an effect of tinnitus is disclosed. The method includes the following steps: acquiring a sound frequency of a tinnitus sound of a user, and playing a plurality of pure tones within a frequency range during a playback time, wherein the plurality of pure tones include a plurality of first pure tones and a plurality of second pure tones; the plurality of first pure tones and the sound frequency are located at a first frequency area, and the plurality of second pure tones are located at a second frequency area; the first frequency area covers X Hz, where 100X12000, the second frequency area covers the remaining portion of the frequency range excluding the first frequency area, and the plurality of first pure tones accounts for M % of the plurality of pure tones, where 50<M90.

Representative embodiments are directed to detecting neurological activity in a patient. The detection of neurological activity includes identifying cross-frequency coupling and determining whether the cross-frequency coupling is physiological or pathological. When pathological cross-frequency coupling is detected, neurostimulation of one or more sites is applied. In some embodiments, an implantable pulse generator is adapted to analyze neural activity for pathological cross-frequency coupling and to provide electrical stimulation in response to the detected pathological cross-frequency coupling.

Described and disclosed herein are various embodiments of systems, devices, components and methods configured to employ acoustic coordinated reset neuromodulation therapies that are capable of adjusting or modulating at least one of the intensity, auditory filter bandwidth, and center frequency of therapeutic stimulation signals delivered to an individual patient, where in one embodiment such signals are tuned to have intensities that are above or slightly above the individual patient's hearing threshold.

A method of assessing the effect of viewing varying colours of light on a subject's perception of tinnitus, comprising the steps of: presenting a display in at least part of the subject's Held of view; illuminating the display with coloured light in the visible spectrum using one or more variable sources, varying measurable values of the coloured light illuminating the display; and recording the measurable values of the coloured light illuminating the display at which the subject indicates a change in their perception of tinnitus. Also provided are methods of determining which tristimulus values of light can be used to alleviate a subject's perception of tinnitus, methods of producing data sets of measurable values of coloured light, use of coloured light, articles formulated to modify illumination of at least part of the visual field of a subject, a method of alleviating a subject's perception of tinnitus and use of apparatus for assessing the effect of viewing varying colours of light on a subject's perception of tinnitus.

Apparatuses and methods for matching the tinnitus of a subject are provided. A plurality of sounds are applied to a subject. The plurality of sounds includes a plurality of first sounds and further includes a plurality of second sounds. A first likeness score associated with the plurality of the sounds is received. Each first likeness score is representative of the similarity of the sound associated therewith to the tinnitus of the subject. At least one third sound is generated based on at least one of the plurality of first sounds and based on at least one of the plurality of second sounds. The at least one third sound is generated based on the first likeness scores associated with the plurality of sounds. A fourth sound is determined based on the at least one third sound. The fourth sound matches the tinnitus of the subject.

A portable hearing evaluation system is provided including: a portable computing device configured to provide audiometric testing of a patient according to one or more audiological standards; and a transducer, coupled to the portable computing device. The portable computing device is configured generate a plurality of test signals based at least in part according to one or more parameters and to be provided on an output of the portable computing device for playback on the transducer.

Systems, methods, and devices for mapping brain activity to identify therapeutic targets in a patient are disclosed. A set of stimuli is applied to the patient, which includes stimulus that are at least one of provocative, soothing, or neutral with respect to a condition of a patient, for example addiction, phobia, disorder, etc. The patient focuses on one of the stimuli, in some embodiments suppressing the patient's mental or emotional response to the stimuli. As the patient responds to the stimuli, the patient's brain activity is monitored, for example by fMRI. After presenting a series of sets of stimuli to the patient and monitoring the patient's brain activity responsive to the stimuli, the brain activity is mapped to the condition based on the type of stimuli corresponding to the brain activity.

Methods and systems are provided for a sound device for making or treatment of tinnitus. In one example, a method includes determining a current sleep cycle and administering a therapy sound based on the current sleep cycle.
