LOW FREQUENCY EVOKED RESPONSE HEARING TEST

描述：(改编自申请者的摘要)这是第一阶段 关于开发听觉刺激和记录技术的建议 对低频敏感的脑干听力测试(ABR) 听觉阈值。目前，ABR测试使用点击或低频 音调零点很难反映低频阈值。这个 研究人员将使用专门设计的低频刺激来 唤醒ABR，结合高频掩蔽器消除 高频光纤的混杂作用。这个 研究人员建议在听力正常的两种情况下测试这项技术 成人和在这一阶段患有高频听力损失的成年人 项目。

DESCRIPTION: (Adapted from the applicant's abstract) This is a Phase I proposal to develop stimuli and recording techniques for auditory brainstem hearing tests (ABR) that will be sensitive to low-frequency auditory thresholds. Currently, ABR tests using clicks or low-frequency tone pips have difficulty in reflecting low-frequency thresholds. The investigator will use a specially designed low-frequency stimulus to evoke the ABR, in combination with a high-frequency masker to eliminate the confounding contributions of the high-frequency fibers. The investigator proposes to test this technique in both normal-hearing adults and adults with high-frequency hearing loss in this phase of the project.
