耳声发射 (OAE) 是内耳产生的低强度声音,可对耳蜗健康状况进行非侵入性评估。高级应用需要记录各种频率和刺激水平的 OAE。这里详细介绍了一种在广阔的刺激空间中有效测量失真产物耳声发射 (DPOAE) 的方法。具体来说,DPOAE 是通过同时扫描多个频率水平的诱发刺激来记录的。该方法可在几分钟内生成多个 f2 频率的 DPOAE 生长函数。结果表明,扫描水平方法产生的 DPOAE 与传统(离散刺激)范式中测量的 DPOAE 相当,但具有多个优点。
Otoacoustic emissions (OAEs) are low-level sounds generated by the inner ear that provide a non-invasive assessment of cochlear health. Advanced applications require recording OAEs across a wide range of frequencies and stimulus levels. Detailed here is a method for efficiently measuring distortion product otoacoustic emissions (DPOAEs) across an expansive stimulus space. Specifically, DPOAEs are recorded by sweeping the evoking stimuli in level across multiple frequencies simultaneously. This method generates DPOAE growth functions at multiple f2 frequencies in several minutes. Results indicate the swept level method yields DPOAEs equivalent to those measured in a traditional (discrete stimulus) paradigm, but with several advantages.
