前言众所周知,人们一般用扬声器的频率响应曲线和相位响应曲线来描述扬声器的电声性能。而测量扬声器的频率响应曲线和相位响应曲线,不仅需要一条特定的音频测量仪器,而且必须在满足一定条件的消声室中测量。要建造一座消声室不仅造价昂贵,而且要求特殊、施工困难。我国除了在一些大城市的个别单位建了消声室外,一般都没有消声室,这就给扬声器的性能测量和改进工作带来了一定的困难。此外,我们还知道,扬声器性能的主客观
Preface As we all know, people generally use the speaker’s frequency response curve and phase response curve to describe the speaker’s electro-acoustic performance. Measuring the frequency response and phase response of the loudspeaker requires not only a specific audio measuring instrument but also the anechoic chamber that meets certain conditions. To build an anechoic chamber is not only expensive, but also requires special and difficult construction. In addition to building anechoic chambers in some large cities in our country, there is no anechoic chamber in general, which brings certain difficulties to the performance measurement and improvement of the loudspeakers. In addition, we also know that subjective and objective speaker performance
