吸声特性 meaning in English
acoustic performance
acoustical performance
sound absorption characteristic
Examples
- Investigation of the sound absorption performance of multilayer non - homogenous wave - guide
多层非均匀波导吸声特性研究 - Acoustics - measurement of sound absorption properties of road surfaces in situ - part 1 : extended surface method iso 13472 - 1 : 2002
声学.现场路面吸声特性的测量.第1部分:扩展表面法 - Based of this , we design new plans and make some experiments on these new material and structure , and finally improve the noise environment in engine compartment
在此基础上设计出新的方案，选用了新材料，进行了吸声系数的驻波管法测量，验证了材料的吸声特性，取得了很好的降噪效果。 - These are not really loads but indicate surfaces that absorb sound . specify the degree of sound absorption as the material property mu ( boundary admittance or absorption coefficient )
也就是说它的作用是使得边界吸声材料的吸声特性得以发挥。如果是0 ，就是不发生吸声现象。相反，是1 ，就是说明是吸声材料的吸声特性完全发挥。 - To provide a method that can be used to predict single or multi - layered microperforated panel ( mpp ) performance precisely , especially when the mpp has holes of different diameter and irregular shape
摘要提出用实验测得含不同孔径孔的微孔板声阻抗率来预测由其形成的单层或多层微孔板的吸声特性，并用传递矩阵法来预测该微孔板的各种组合结构的整体吸声性能。
