Role of Exposure in Hyperacusis

This study focuses on patients with a primary complaint of hyperacusis. Hyperacusis has been defined as 'abnormally reduced tolerance to sound'. It shows a high comorbidity with tinnitus, the perception of sound in the absence of a sound source. For the period of one month, hyperacusis and tinnitus severity and exposure to sounds will be evaluated by use of Ecological Momentary Assessment (EMA) in all participants. A novel approach to assessments, EMA prompts participants during their daily life to answer short questionnaires, increasing ecological validity and minimizing the risk for recall and memory biases. At a randomized time point during the one-month period, participants will individually receive a single psychoeducation session (1h) delivered by an experienced audiologist. The goal of the study is to investigate if the psychoeducation session leads to an increase in exposure to sound and a decrease in hyperacusis severity.

Treatment of Tinnitus With Noninvasive Neuromodulation and Listening Therapy

The goal of this study is to use non-invasive transcranial direct current stimulation (tDCS) combined with active listening therapy to treat tinnitus and hyperacusis and related conditions.

A Feasibility Study of a Novel, Fully Remote Counseling and Sound Therapy Program for Hyperacusis

There is no universal approach used to treat hyperacusis, a condition defined as having reactions to sound as too loud, annoying, fearful, or painful. A collaborative report published by prominent researchers recommended counseling and sound therapy for managing hyperacusis, but emphasized the need for rigorously designed clinical trials to assess the effectiveness of these treatments. The investigators developed a face-to-face counseling approach, Hyperacusis Activities Treatment (HAT), and have demonstrated its effectiveness for in-person therapy. In this study, the investigators will conduct a controlled trial to evaluate the effectiveness of the two components of HAT in managing hyperacusis: Aim 1, remotely delivered counseling, and Aim 2, sound therapy. In Aim 1, participants will complete four weeks of remote counseling using instructional videos, homework activities, discussion forums, and hands-on exercises. To ensure rigor in the approach, all participants will complete 4 weeks of weekly monitoring (control) before beginning counseling (treatment) for an additional 4 weeks. In aim 2, participants will be randomized into one of two sound therapy groups: (1) Group 1: Listen to their individually chosen bothersome sounds using successive approximations or a gradual increase in sound level; and (2) Group 2: Listen to continuous, low-level background noise. In both groups, devices will be fit remotely and used for 1-2 hours per day for four weeks. Completion of this R15 Academic Research Enhancement Award project at Augustana College will lead to a shift in hyperacusis management by providing early clinical evidence for the effectiveness of the components that make up the HAT protocol: counseling and sound therapy.
