摘要
采用驻波管法对不同厚度、不同结构的浒苔样品进行吸声系数的测定,并与相近的有机和无机纤维吸声材料进行了对比。试验结果表明,浒苔具有很好的吸声性能,并且其微管结构对吸声性能的提高有较大的贡献。这些新的发现将给研制新型无机纤维吸声材料提供有益的仿声学启示。
The sound absorption coefficient of Enteromorpha prolifera was analyzed using the standing wave method and was compared with various materials. Results of the experiments show that Enteromorpha prolifera has good absorption property, and the microtubule structure of Enteromorpha prolifera mainly contributes to its absorption property. The results of the study will be helpful in development of new absorbing materials.
