These devices could make hearing assistance more accessible, but delays in sound transmission can be bothersome. Researchers will use an intervention called \"Audio delay,\" where sound is captured by microphones, processed to add an artificial delay, and then played back through headphones. They will change the sound levels and delays to see what is comfortable. The main goal is to understand how disturbing these delays are to listeners. You can join if you are 18 or older, comfortable speaking English, and do not have a speech or hearing disorder.
