一、引言学科的探索、工程设计、产品开发自始至终贯穿了测量技术。电声测量技术也是如此。为什么测量?至今所有的电声测量和研究,都是试图用一组物理参数来表述音频信号的特征。它们是在电声系统中传输和转换的,这些参数是与音质评价紧密相关的客观参数。本文将讨论传统参数和逐年出现的一些新参数,在其演变过程中的思路,亦即这些参数出现的技术背景。测量方法同当时技术的发展紧密相关,仅泛泛地说从机械技术到电子技术,又将电子技术分为电子管、晶体管到集成电路又发展到计算机技术这样说法是不够的。因为这些技术对电声测量只提供了新的手段或新的工具,重要
First, the introduction of discipline exploration, engineering design, product development throughout the measurement technology. Electroacoustic measurement technology is also true. Why Measurement? So far all the electro-acoustic measurement and research, are trying to use a set of physical parameters to characterize the audio signal. They are transmitted and converted in the electro-acoustic system, and these parameters are objective parameters that are closely related to the sound quality evaluation. This article will discuss the traditional parameters and some new parameters that emerge from year to year. The ideas in their evolution, that is, the technical backgrounds in which these parameters appear. The measurement method is closely related to the development of the technology at the time. It is not enough to simply say that mechanical technology to electronic technology and electronic technology are divided into electronic tubes and transistors to integrated circuits and then to computer technology. Because these techniques only provide new means or new tools for electroacoustic measurements, it is important
