Amplification Strategies to Reduce Tinnitus: A Paired Comparison Method

Area of Science:

• Audiology
• Hearing Science
• Otoacoustic Emissions

Background:

• Investigates optimal hearing aid amplification for tinnitus relief in sensorineural hearing loss.
• Focuses on individuals experiencing bothersome tinnitus in quiet environments.

Purpose of the Study:

• To determine the most effective hearing aid amplification strategy for tinnitus alleviation.
• To compare different fitting methods and compression thresholds for tinnitus management.

Main Methods:

• Employed a repeated measures design with 20 participants (25-65 years) with hearing loss and tinnitus.
• Utilized paired comparison to assess preference for four amplification strategies (DSL i/o and NAL-v1 at low/high compression).
• Assessed tinnitus severity pre- and post-intervention using the Tinnitus Severity Index.

Main Results:

• The desired sensation level (input/output) at a low compression threshold was identified as the superior strategy for tinnitus relief.
• Significant differences in tinnitus relief were found across strategies, with DSL i/o at low compression preferred by 35% of participants.
• A significant reduction in tinnitus severity was observed after 1 month of using the preferred hearing aid program.

Conclusions:

• The desired sensation level (input/output) method, specifically at a low compression threshold, is recommended for alleviating bothersome tinnitus.
• This amplification strategy demonstrates efficacy in improving tinnitus symptoms in individuals with sensorineural hearing loss.
