Impact of Ambient Noise on Hearing Screening
There is a trend toward point of care audiological testing that is performed outside of a sound proof booth. Such strategies are particularly suited to low resource environments, where audiological facilities are limited and care often must be provided in remote settings. The authors will review the ambient noise challenges of screening pure tone threshold exams in 1350 schoolchildren in rural Nicaragua. Optimal noise management was able only to reduce the pre-testing noise level to 48 dBA. Moreover, transient noise contamination during testing reached much high levels that affect test results. Strategies for reducing ambient noise effects will be discussed.
Alternatives to pure tone testing include with speech in noise testing methodology, including digits in noise testing where a triplet of numbers in presented over a background noise level. Because this method utilizes background noise in the testing paradigm, it is presumed to be relatively impervious to ambient noise levels. We will discuss the utility of these methods in high ambient noise environments.
- Describe the challenges of managing ambient noise in point of care hearing testing
- Discuss the potential effects of ambient noise on speech in noise testing
