| 中文摘要: |
| 研究使用薄橡胶条倾斜固定于水箱壁面的吸声结构(百叶窗式吸声结构)的吸声特性.基于物理声学方法计算了这一结构的吸声系数,并用混响室法测量了这一结构的吸声性能.理论计算和实验结果表明,在水箱中敷设这种百叶窗式吸声结构能够在宽频带范围内获得较佳的吸声效果,如果调整结构参数可以改变吸声的频带范围. |
| 英文摘要: |
| A sound absorption structure (the shutter-like absorption structure) has been studied, which is made by fixing thin rubber on pool wall. Based on the physical acoustic method absorption coefficient is calculated, also the sound absorption properties are measured by using reverberation method. Theoretical Calculation and experimental result show that within a wide frequency band the shutter-like absorption structure performs well in pool. And, if the structural parameter is adjusted, the frequency range will change. |
