The implant may be configured to best accommodate the patient's comfort and sleeping habits (e.g., set a delay based on sleep latency). The hypoglossal nerve stimulator implantable pulse generator battery life typically lasts 8–12 years, after which the implantable pulse generator may be safely replaced with another surgery. [8]
The ear has a resonance frequency (highest frequency response) at 3,000 Hz and rolls off at a very steep 26 dB/octave on the high frequency side. Unfortunately, most tinnitus is associated with hearing loss, and most hearing loss and tinnitus is high frequency. Most maskers are limited to about 6,000 Hz of effective output.
The second is tailored music therapy, notched at the tinnitus frequency, which may affect lateral inhibition of the notched neural region, suppressing tinnitus. [ 108 ] [ 109 ] There is some tentative evidence supporting tinnitus retraining therapy , which aims to reduce tinnitus-related neuronal activity.
Those most likely to have a favorable outcome from TRT are those with lower loudness of tinnitus, higher pitch of tinnitus, shorter duration of tinnitus since onset, recognition of tinnitus attenuation by sound generator [clarification needed], lower hearing thresholds (i.e. better hearing), high Tinnitus Handicap Inventory (THI) score, [8] and ...
A sweep generator is a piece of electronic test equipment similar to, and sometimes included on, a function generator which creates an electrical waveform with a linearly varying frequency and a constant amplitude. Sweep generators are commonly used to test the frequency response of electronic filter circuits.
Though the pathophysiology of tinnitus is not known, noise exposure can be a contributing factor, therefore tinnitus can be associated with hearing loss, generated by the cochlea and central nervous system (CNS). High frequency hearing loss causes a high pitched tinnitus and low frequency hearing loss causes a roaring tinnitus. [19]
