The value of noise-excluder shells in reducing overreferrals from a school audiometric screening program
Clinical Pediatrics
|June 1, 1977
Summary
Noise-excluding shells in audiometric screening reduce unnecessary referrals to specialty clinics without missing individuals who need follow-up care. This finding is crucial for improving hearing assessment accuracy in noisy settings.
Area of Science:
- Audiology
- Occupational Health
- Hearing Science
Background:
- Audiometric screening in noisy environments frequently leads to overreferrals.
- Accurate hearing assessments are vital for early detection and intervention.
Purpose of the Study:
- To investigate the impact of different headset types on audiometric screening referral rates.
- To determine if noise-excluding shells can mitigate overreferrals in noisy settings.
Main Methods:
- A follow-up study comparing referral rates based on headset type during audiometric screening.
- Evaluation of both overreferral and underreferral rates associated with noise-excluding shells.
Main Results:
- Headsets with noise-excluding shells significantly reduced overreferrals.
- The use of noise-excluding shells did not lead to an increase in underreferrals.
Conclusions:
- Noise-excluding shells are effective in improving the specificity of audiometric screening in noisy environments.
- Implementing noise-excluding shells can optimize resource allocation in audiology and occupational health programs.
