将声分隔片结构用于充水管道，对其消声性能进行了实验研究．主要由吸声橡皮构成的４０ｃｍ 长的声分隔片；在１０ｋＨｚ－１００ｋＨｚ的频率范围内，测得其传递损失在１０ｄＢ左右．
The structure of acoustic separator was used to fill the water pipe, and its anechoic performance was experimentally studied. Mainly by the sound-absorbing rubber composition of 40cm long sound separator; in the frequency range of 10kHz-100kHz, measured transmission loss of about 10dB.
