摘　　要：在声学测量系统中 ,要求消声水池能在测量频段内达到近似自由场的声学环境 ,吸声尖劈可以对消声水池进行被动消声处理。本文介绍了一种能满足消声水池消声处理要求的低频吸声尖劈的设计要求、材料、结构设计。In acoustic measure system, the noise elimination of the anechoic pool is an important link. It demands reaching a free field acoustic environment. A low frequency sound absorption taper which may meet the requirement of noise elimination is introduced in this paper covering materials, structure design and layout of the taper.
