摘    要:本文提出了小试件轻结构隔声测量的一种新方法。这种方法,声源放在一个混响室内,而接收室是一个小的消声箱。详细地描述了测量的装置。测量了几个试件,结果与“质量定律”很好地一致。在需要测量具有高隔声量的小试件时,这个方法更加有用。另外还讨论了装置的限制与精度。 关键词

Abstract:In this paper, a new method is proposed for the measurements of sound insulation of light structures using small samples. The sound source is placed in a reverberation room, and the receiving room is a small anechoic box. The arrangement of the measurement is described in betail. Several samples are measured and the results agree well with the mass law. The method does provide a useful alternative where the measurements for the samples of small dimensions with high transmission loss are required. Limitations of the equipment and evaluation of accuracy are also discussed.
