一、引言众所周知,用试听节目带试听电声传输系统的各种装置时,虽然它们的电声参数很相似,但听起来好象它们具有不同的音质。另一方面,对同样的扬声器用不同的节目进行试听,所得到的结论也不完全一致。Staffeldt利用客观和主观测量方法对扬声器作比较后发现;用 Zwicker 氏法计算出的响度,和主观音质评价之间没有什么关系。这个结论似乎与声学工程中所看到的结论相矛盾。国际无线电 I. INTRODUCTION As we all know, audition programs with audition audio listening transmission system of various devices, although their electroacoustic parameters are very similar, but it sounds as if they have different sound quality. On the other hand, auditioning different programs on the same speakers did not lead to the same conclusion. Staffeldt used objective and subjective measurements to compare loudspeakers; the loudness calculated using Zwicker’s method was not related to the subjective evaluation of the sound quality. This conclusion seems to contradict the conclusions of acoustic engineering. International radio
