To objectively evaluate the effect of hearing aids.
The procedure involved eliciting ABRs by clicks and slow vertex response (SVRs) by tone pips to the aided and unaided ear presented in sound field.
There has high relativity between the thresholds of SVRs and free field pure tone audiometry. There has no significant difference between the gains from SVRs and free field pure tone audiometry.
客观评估助听器的效果。
该程序包括通过短声诱发听性脑干反应（ABR）以及通过短纯音诱发慢顶点反应（SVR），分别针对声场中佩戴助听器和未佩戴助听器的耳朵进行测试。
慢顶点反应阈值与自由声场纯音听力测试结果之间具有高度相关性。慢顶点反应增益与自由声场纯音听力测试增益之间无显著差异。
