Abstract
OBJECTIVES
To determine the effect of spectral differences between stimuli used for verification of hearing aid gain in nonlinear devices.
DESIGN
The spectra of nine stimuli from five analyzing systems were obtained.
RESULTS
Most stimuli closely duplicated one of two well-specified spectra. The difference between these two input spectra resulted in measured gain differences of up to 8 dB.
CONCLUSIONS
Careful consideration of selected test stimulus for measuring hearing aid gain is recommended.
摘要
目的
确定非线性设备中用于验证助听器增益的刺激之间光谱差异的影响。
设计
获取来自五个分析系统的九个刺激的光谱。
结果
大多数刺激非常接近两种特定光谱之一。这两种输入光谱之间的差异导致测量增益差异最大可达 8 dB。
结论
建议在测量助听器增益时仔细考虑所选测试刺激。
