Abstract

A simple procedure for measuring changes in the acoustic impedance of the ear is described. The technique has several applications, including simulation using a standard coupler of changes in real ear impedance produced by the acoustic reflex. The technique has also been used for calibrating the response time of an otoadmittance meter used in measuring the temporal characteristic of reflex activity.

摘要

本文描述了一种测量耳部声阻抗变化的简单方法。该技术有多种应用，包括使用标准耦合器模拟声反射引起的真实耳阻抗变化。该技术还被用于校准用于测量反射活动时间特性的耳声导抗仪的响应时间。
