标准范围

ISO 8253-2:2009规定了相关的测试信号特性、自由、漫反射和准自由声场的要求，以及使用纯音、调频音或通过一个或多个扬声器呈现的其他窄带测试信号进行声场测听的程序。主要目的是确定125 Hz至8 000 Hz频率范围内的听阈水平，但该范围可扩展至20 Hz至16 000 Hz。ISO 8253-2:2009不包括手持式扬声器的使用规范。不包括作为测试信号的语音。ISO 8253-2:2009的目的是确保使用声场测听法进行的听力测试具有尽可能高的准确性和再现性。给出了结果的图形表示示例。

ISO 8253-2:2009 specifies relevant test signal characteristics, requirements for free, diffuse, and quasi？free sound fields, and procedures for sound field audiometry using pure tones, frequency-modulated tones or other narrow-band test signals presented by means of one or more loudspeakers. The primary purpose is the determination of hearing threshold levels in the frequency range 125 Hz to 8 000 Hz, but this range can be extended to 20 Hz to 16 000 Hz.ISO 8253-2:2009 does not include specifications for the use of hand-held loudspeakers. Speech as a test signal is not covered.The purpose of ISO 8253-2:2009 is to ensure that tests of hearing, using sound field audiometry, give as high a degree of accuracy and reproducibility as possible.Examples of graphical representations of the results are given.
