谈谈音箱在消声室测量中低频响应的缺失

Discussion on Low Frequency Response Loss of Loudspeaker Box in Anechoic Chamber

在消声室中测量音箱的频响曲线时,往往会造成低频响应的丢失,这通常是由于被测音箱的位置不在消声室的自由声场而引起的。本文指出了在消声室中测量音箱的频响时必须注意的几个问题。

When the frequency response of the loudspeaker box is measured in the anechoic chamber, the low frequency response is often lost, which often happens when the position of the speaker box is not in the free field of the anechoic chamber. This paper also points out several key points which should be paid attention to when the frequency response of the loudspeaker box is measured in the anechoic chamber.
