A case of contaminated functional gain measures from internal hearing aid noise is presented and clinical implications addressed. The contaminated functional gain measures underestimated real ear insertion gain. Recognition of this source of functional gain measurement error is essential for accurate hearing aid fitting.
本文介绍了一例因内置助听器噪声导致功能增益测量结果受污染的病例，并探讨了其临床意义。受污染的功能增益测量结果低估了真耳插入增益。认识到这种功能增益测量误差的来源对于准确的助听器验配至关重要。
