Understanding Delay in Hearing Assistive Technology

This study is looking at how much delay people can tolerate when using wireless remote microphones, like those found in smartphones. 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. This study is currently unclear on its recruitment status.

Study design
This interventional study plans to enroll 60 participants to understand the effects of audio processing delay.
What's involved
You will experience varying sound levels and delays through headphones, with your subjective disturbance measured at approximately 1-minute intervals.
Compensation
Not stated in the trial record.
Follow-up
Your subjective disturbance will be measured at approximately 1-minute intervals during the study.

Eligibility criteria

Inclusion

Comfortable conversing in English

Exclusion

Speech or hearing disorder
  • Subjective disturbanceApproximately 1 minute intervals

    Participants will rate their level of annoyance on a numerical scale from 1 to 7, where 1 indicates no annoyance (the sound seems normal) and 7 is intolerable (it is difficult to communicate). Lower is better.
