|June 1, 1984
Summary
The Welch Allyn AudioScope can reliably screen hearing using specific eartips. This study identified the best eartip configuration for accurate audiometric data collection.
Area of Science:
- Audiology
- Medical Devices
Background:
- The Welch Allyn AudioScope is a handheld device for hearing screening.
- Accurate audiometric data is crucial for effective hearing assessment.
Purpose of the Study:
- To evaluate the Welch Allyn AudioScope as a reliable audiometer screening instrument.
- To determine the optimal eartip configuration for audiometric data accuracy.
Main Methods:
- Utilized a threshold, loudness balancing technique for evaluation.
- Compared two eartip configurations for reliability.
- Applied the American National Standard Method for Coupler Calibration of Earphones.
Main Results:
- Reference threshold sound pressure levels were developed for the AudioScope.
- The most reliable eartip configuration for audiometric purposes was identified.
Conclusions:
- Guidelines for the use of the Welch Allyn AudioScope as an audiometric screening instrument are proposed.
- The study provides recommendations for maximizing the reliability of hearing screening with this device.
