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. Higher frequency ...
In Frey's tests, a repetition rate of 50 Hz was used, with pulse width between 10–70 microseconds. The perceived loudness was found to be linked to the peak power density, instead of average power density. At 1.245 GHz, the peak power density for perception was below 80 mW/cm 2. According to Frey, the induced sounds were described as "a buzz ...
Neurostimulation technology can improve the life quality of those who are severely paralyzed or have profound losses to various sense organs, as well as for permanent reduction of severe, chronic pain which would otherwise require constant (around-the-clock), high-dose opioid therapy (such as neuropathic pain and spinal-cord injury).
Transcranial direct current stimulation (tDCS) is a form of neuromodulation that uses constant, low direct current delivered via electrodes on the head. This type of neurotherapy was originally developed to help patients with brain injuries or neuropsychiatric conditions such as major depressive disorder.
TMS can be used clinically to measure activity and function of specific brain circuits in humans, most commonly with single or paired magnetic pulses. [8] The most widely accepted use is in measuring the connection between the primary motor cortex of the central nervous system and the peripheral nervous system to evaluate damage related to past or progressive neurologic insult.
His main research topic is the understanding and treatment of phantom perceptions such as pain [2] and tinnitus, [3] [4] as well as addiction, using non-invasive neuromodulation (transcranial magnetic stimulation, transcranial direct-current stimulation, transcranial alternating current stimulation, transcranial random noise stimulation, tPNS ...
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 ...
Environmental noise regulations usually specify a maximum outdoor noise level of 60 to 65 dB(A), while occupational safety organizations recommend that the maximum exposure to noise is 40 hours per week at 85 to 90 dB(A). For every additional 3 dB(A), the maximum exposure time is reduced by a factor 2, e.g. 20 hours per week at 88 dB(A).
