Purpose

Wireless assistive listening systems can dramatically improve intelligibility in noisy environments, but they are cumbersome to use. Digital consumer devices, such as smartphones, could be more accessible and user-friendly, but they suffer from transmission delays that could be disturbing to listeners. Delay has been studied extensively for in-ear devices such as hearing aids, but not for remote microphone systems. This study aims to characterize the tolerable delay for wireless remote microphones both for both the user's own speech and for external sounds. This will provide valuable information for engineers designing next-generation assistive listening systems.

Effects of Delay in Hearing Assistive Technology
  • Other: Audio delay
    Audio will be captured by several microphones, processed to add an artificial delay, and then played back through headphones. The sound levels and delays for each microphone will be varied.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
