American National Standard Procedure for the Computation of Loudness of Steady Sounds 计算稳定声音响度的美国国家标准程序
发布日期: 2007-05-24
本标准规定了计算听力正常的听者感知到的稳定声音响度的程序。该程序基于声音的光谱。可能的声音包括简单和复杂的音调(谐波和非谐波)以及噪声带。本标准适用于在正面入射的自由场、漫射场或通过耳机呈现的声音。提供了一个计算机程序,该程序以sones为单位执行计算并提供估算值,以phons为单位提供相应的loundes水位。合规性不要求使用本软件。此项目的可下载版本为“.zip”文件,其中包含标准的PDF版本以及软件程序文件。
This standard specifies a procedure for calculating the loudness of steady sounds as perceived by listeners with normal hearing. The procedure is based on the spectra of the sound. The possible sounds include simple and complex tones (both harmonic and inharmonic) and bands of noise.The standard is applicable to sounds presented in free field with frontal incidence, in a diffuse field, or via headphones.A computer program, which performs the computation and provides estimate in sones, and the corresponding loundes level in phons, is provided. Use of this software is not required for conformance.The downloadable version of this item is a ".zip" file which contains a PDF version of the standard as well as the software program files.
