What You Need to Know Before You Apply

What is the purpose of this trial?

The goal of this clinical trial is to establish how speech understanding is affected by background noise in people with normal hearing. The main questions it aims to answer are:

* Does noise affect speech understanding similarly in all frequency regions?

* Does adding noise cause speech understanding to fall away at a similar rate across frequencies?

Participants will listen to speech in different frequency regions, with noise added at various levels, and respond with the words that they hear.

Are You a Good Fit for This Trial?

This trial is for adults with normal hearing who do not have any known hearing loss or deafness. Participants should be healthy and able to listen and respond to speech tests.
