Electroacoustic performance characteristics of FM auditory trainers
The Journal of Speech and Hearing Disorders
|February 1, 1980
Summary
This study compared the electroacoustic performance of FM auditory trainers in FM and EM modes. Results show performance differences between modes, necessitating assessment in both for full evaluation.
Area of Science:
- Audiology
- Acoustics
- Hearing Aid Technology
Background:
- FM auditory trainers are crucial assistive listening devices.
- Understanding their electroacoustic performance is vital for optimal function.
- Existing hearing aid evaluation methods may or may not apply.
Purpose of the Study:
- To investigate electroacoustic performance differences between FM and EM modes in auditory trainers.
- To determine the appropriateness of hearing aid evaluation standards for FM trainers.
- To assess the impact of volume control taper on trainer performance.
Main Methods:
- Comparative analysis of electroacoustic performance metrics.
- Application and adaptation of ANSI S3.22-1976 hearing aid testing procedures.
- Experimental assessment of volume control dial taper effects.
Main Results:
- Significant electroacoustic performance variations exist between FM and EM modes.
- ANSI S3.22-1976 procedures can be cautiously applied to FM trainer measurements.
- Volume control taper influences trainer performance characteristics.
Conclusions:
- Full electroacoustic assessment requires evaluating FM auditory trainers in both EM and FM modes.
- Standardized testing protocols need careful consideration for FM trainer evaluation.
- Performance nuances necessitate mode-specific analysis for accurate characterization.
