Brief Summary
There are no widely available treatments for the underserved populations with tinnitus, hyperacusis, and hearing-in-noise deficits. Left unmanaged, these disorders can lead to a wide range of negative psychosocial and emotional sequelae including anxiety, depression, fear, and social isolation. The proposed research will investigate a novel closed-loop sound therapy designed to address the mutual basis of these disorders.

Outcome Measures
Primary Outcomes (3)
Change in Score on the Tinnitus Reaction Questionnaire
Pre-test / Post-test (6 weeks) / Follow-up (14 weeks)
Reduction in Loudness Discomfort Levels
The intensity of pulsated pure tones of 55 ms reported to be uncomfortably loud (test commonly employed in hearing aid fitting).
Pre-test / Post-test (6 weeks) / Follow-up (14 weeks)
Change in Speech Recognition in Noise Performance Accuracy
Keyword recognition accuracy for sentences in noise will be assessed with a clinical test, the QuickSiN. Signal to noise ratios vary from 25 to 0 dB in 5 dB steps.
Pre-test / Post-test (6 weeks) / Follow-up (14 weeks)
Study Arms (2)
Sound Therapy Group 1
EXPERIMENTALClosed-loop sound therapy. Weekly sessions over 6 weeks.
Sound Therapy Group 2
PLACEBO COMPARATORPlacebo sound therapy. Weekly sessions over 6 weeks.
