Summary

This trial will examine how adjusting hearing aid settings to manage sudden sounds affects speech comprehension and recall in people with hearing loss. Participants will undergo tests to assess their hearing, medical history, and cognitive abilities.

Who is the study for?
This trial is for individuals with hearing loss who can hear sounds between 25-70 dB HL from 2000 - 6000 Hz and are native English speakers. It's not suitable for those with retrocochlear hearing loss, which involves issues beyond the cochlea in the inner ear.
What is being tested?
The study tests how different sudden sound reduction settings on hearing aids affect speech understanding and memory. Participants will be evaluated through listening experiments to measure sentence recognition and recall, as well as subjective comfort ratings.
What are the potential side effects?
While there aren't direct side effects like in drug trials, participants may experience discomfort or dissatisfaction with certain sudden sound reduction settings based on personal preference and performance during the tests.
