Transitional Intervention for Hyperacusis in Autism

Official title: Effectiveness of an Individualized Progressive Treatment for Expanding Sound Tolerance in Adults With Autism Spectrum Disorder: A Crossover Randomized Controlled Trial (RCT)

Run by University of Central Florida · NCT07798297 · Data updated 2026-11-12

Aiming to see if a transitional sound-therapy approach can help adults with autism tolerate everyday sounds better and reduce loudness-related distress.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–39 with autism spectrum disorder and clinically significant loudness hyperacusis (HQ score ≥ 22 and LDLs ≤ 80 dB HL in at least one ear) who can consent in English and commit to the visit schedule.

Probably not a fit

Individuals without the targeted hyperacusis profile or those with exclusion criteria may not experience benefit.

What this trial studies

This trial tests a transitional intervention designed to shift individuals with autism from heavy sound avoidance to active exposure therapy to improve loudness tolerance. Participants with mild-to-severe loudness hyperacusis and ASD are randomized to receive the intervention immediately or after a delay, with daily diary tracking and monthly clinical visits over 12 months. Outcomes focus on changes in loudness tolerance and hyperacusis-related symptoms measured before, during, and after treatment. The study includes adults ages 18–39 with specific audiometric and cognitive criteria and excludes recent head trauma or other limiting conditions. Conducted at two U.S. centers, the trial aims to establish feasibility and potential benefit of this approach for ASD-related hyperacusis.

Why it matters

Potential benefit: If successful, participants may experience greater tolerance to everyday sounds and an improved quality of life.

How similar studies have gone: Previous similar sound-therapy approaches in sensory processing have shown mixed results; this study tests a specific transitional method in the ASD hyperacusis population.
