评价一套音响系统是否达到高保真标准,其各项技术指标必须满足一定的要求。由于电声设备挡级不同,其技术指标和等级标准也不一样。一般评价的技术指标有失真度、频率响应、信噪比与动态范围、瞬态响应、立体声分离度和平衡度五部分。
Evaluation of a sound system to achieve high fidelity standards, the technical indicators must meet certain requirements. As the electro-acoustic equipment block level is different, its technical indicators and rating standards are not the same. General evaluation of the technical indicators are distortion, frequency response, signal to noise ratio and dynamic range, transient response, stereo separation and balance of five parts.
