| Abstract: | 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. |
