Abstract

A correction for custom in-the-ear nondirectional hearing aids is obtained for converting a frequency response measured using a 2 cm3 coupler to an insertion response, approximating that measured using a manikin and ear simulator. The results are compared to those of a previous published study. The methods used for obtaining the responses make use of a signal analyzer with discrete Fourier transform capabilities.

摘要

针对定制入耳式非定向助听器，已获得一种校正方法，用于将使用2立方厘米耦合器测量的频率响应转换为插入响应，该插入响应近似于使用人体模型和耳朵模拟器测量的结果。将这些结果与之前发表的一项研究结果进行了比较。用于获取响应的方法利用了具有离散傅里叶变换功能的信号分析仪。
