Observational Study on Age-Related Central Hearing Loss
This observational study aims to better understand central hearing loss, which is when your brain has trouble understanding sounds, especially in noisy places. Unlike other types of hearing loss, central hearing loss doesn't have a clear treatment yet. Researchers will use routine audiological assessments (hearing tests) to evaluate how younger and older individuals process sounds and focus on conversations. The study is looking for 200 participants between 40 and 89 years old who have no worse than mild hearing loss and score well on a cognitive screening. Success will be measured by how well participants perform on speech-in-noise tests, brainstem response tests, and spatial hearing tests over an average of 6 years.
- Study design
- This is an observational study with a planned enrollment of 200 participants. It is not a treatment study, but rather aims to understand central hearing loss.
- What's involved
- You would undergo routine audiological assessments. These assessments will be evaluated to help researchers understand central hearing loss.
- Compensation
- Not stated in the trial record.
- Follow-up
- Participants will be followed for an average of 6 years, with measurements taken throughout this period.

What this trial measures
- Speech in Noise Performancethrough study completion, an average of 6 years
Auditory perception task requiring participants to discriminate speech sound in quiet and in back ground noise. Takes about 90min.
- Auditory Brainstem Responsethrough study completion, an average of 6 years
Non-invasive auditory electrophysiological measure of brainstem electrical activity captured using electrodes placed on the scalp while sounds are played to one or both ears. Takes about 60min
- Spatial Acuitythrough study completion, an average of 6 years
Auditory perception task requiring participants to judge the location of a sound. Takes about 90min
