为了衡量组合音响的技术性能,人们常用若干技术指标来表达,这些电声技术指标的物理意义如下。1.频率特性:组合音响的频率特性又称频率响应,它是指组合音响系统能重放声源节目信号的频率范围,以及在该频率范围内振幅允许的偏离量,通常用分贝
In order to measure the technical performance of the composite audio, people often use a number of technical indicators to express the physical meaning of these electro-acoustic technical indicators are as follows. 1. Frequency characteristics: the frequency response of the composite audio frequency characteristics, it refers to the combined audio system can reproduce the frequency range of the sound source program signal, as well as within the frequency range of the amplitude of the allowable deviation, usually in decibels
