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。
在消聲室中測量音箱的頻響麯線時，往往會造成低頻響應的丟失，這通常是由于被測音箱的位置不在消聲室的自由聲場而引起的。本文指齣瞭在消聲室中測量音箱的頻響時必鬚註意的幾箇問題。

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.
