GB/T 15953-1995 in English

《GB/T 15953-1995耳声阻抗/导纳的测定仪器》由TC23（全国电声学标准化技术委员会）归口，主管部门为工业和信息化部（电子）。
本标准包括仪器设计，主要是用226Hz探头音测量外耳声阻抗/导纳的模量。本标准还明确了由生产厂规定的特性，给出了4种型别的性能指标以及为其中三种型别所应提供的设施。还规定了例行校准之外的型式批准测试所用的方法。

Scope

This standard includes instrument design, mainly to measure the modulus of the acoustic impedance/admittance of the external ear with a 226Hz probe tone. This standard also clarifies the characteristics specified by the manufacturer, gives the performance indicators of the four types and the facilities that should be provided for the three types. It also specifies the methods used for type approval testing other than routine calibration. The purpose of this standard is to assure that measurements with comparable test conditions using different instruments conforming to this standard can agree. This standard is not intended to constrain the development and utilization of new features, nor to discourage innovative approaches.
