摘要
探讨扬声器低频测试中的问题,诸如消声室中自由声场的偏差问题,标准障板的衍射误差以及数字测量技术中的低频限制等,在此也提出了某些改进方法。
The problems on low frequency measurement of loudspeaker unit are discussed in this paper, these are the devi- ation of free field in anechoic room, the diffraction error of the standard baffle, and the low frequency limit in digital measur- ing. Some improvements are raised.
