| 摘 要： | 通过对羊毛吸声材料的吸声系数与声衰减能力的测试,发现其吸声性能优良.羊毛吸声材料的吸声系数和声衰减能力随着频率的增大而逐渐增强,羊毛毡的厚度越厚,吸声系数和声衰减能力越大.在羊毛毡表面覆有铝箔,不仅方便使用和运输,而且可以明显地提高其吸声的能力.厚度为20 mm的羊毛毡就可以降低约20 dB的噪声.

| Abstract: | Testing and investigation of Sound Absorption Coefficient(SAC) and Sound Attenuation(SA) show sound-absorbing wool materials have excellent sound absorption properties.The capabilities of SAC and SA expand with the increase of frequency.The thicker the materials are,the better the performances of SAC and SA.Under the protection of Aluminum foil,woolen felt can not only facilitate its usage and transportation,but can also evidently improve its sound absorption capacity.Such sound-absorbing wool materials with a thickness of 20mm can reduce noise by about 20dB. |
