Acoustic material and wire harness with acoustic material |
| 摘要 |
It is aimed to provide a sound-absorbing material and a wiring harness with sound-absorbing material capable of absorbing sound in a wide frequency range from a low frequency to a high frequency and avoiding a weight increase. A sound-absorbing material 1 is configured by laminating base material sheets 3 using non-woven fabrics and a skin material sheet 2 having a smaller basis weight than the base material sheets 3 such that the skin material sheet 2 is arranged between the plurality of base material sheets 3 and an air permeation amount of the sound-absorbing material is within a range of 5 to 50 cm3/cm2·s. |
