Auditory Diseases, Central study: Phonak Lumina P90
Official title Comparing Hearing Aid Fitting Methods in Blast-exposed Veterans
ClinicalTrials.gov ID: NCT06309264
What this study is testing
- What it's testing
- The study will see if a speech‑based fitting method improves speech‑in‑noise performance and brain activity compared with the usual fitting method.
- Who it's for
- Veterans who were exposed to blasts, have normal pure‑tone hearing tests, but report difficulty hearing in challenging environments.
- What's involved
- Participants will receive low‑gain hearing aids programmed either by the standard method or by speech‑based audiometry, then complete speech‑in‑noise tests and a functional brain scan while listening.
- Time commitment
- The trial involves a few study visits over several weeks, including hearing‑aid fitting, testing sessions, and a neuroimaging appointment.

Who can take part
Ages 18 to 60. Healthy volunteers may be eligible.
You may be able to join if
- pure-tone average (PTA) at 0.5, 1, 2, 4 kHz of 35 dB HL or better in each ear;
- pure-tone thresholds no worse than 40 dB HL at any two audiometric frequencies up to 8 kHz;
