| 中文摘要: |
| 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． |
| 英文摘要: |
| In the present paper, acoustical splitter inserted in water-filled duct for noise reduction is studied experimentally. The splitter is made of sound absorbing rubber and the transmission loss in duct is measured. The results of the experiment show that transmission loss of about 10dB can be obtained with the splitter 40 cm long, in the range from 10kHz to 40kHz. |
