音响系统的性能好坏可通过声音的重放来评价,从听音评价的结果可以反映出该器材技术指标的好坏。技术指标分为两大类,一类为静特性指标包括:输出功率,频率特性,信噪比,谐波失真,互调失真,相位失真等;一类为动态特性指标包括:瞬态响应,瞬态互调失真,交界面互调失真等。下表列出了重放声音结果与技术指标间的关系,供大家参考。
Sound system performance is good or bad can be evaluated by the sound playback, listening evaluation can reflect the results of the technical indicators of the equipment is good or bad. Technical indicators are divided into two categories, one for static characteristics include: output power, frequency characteristics, signal to noise ratio, harmonic distortion, intermodulation distortion, phase distortion, etc .; a class of dynamic characteristics include: transient response, Transient intermodulation distortion, interface intermodulation distortion and so on. The following table lists the relationship between the playback sound results and technical indicators for your reference.
