Title:
ACOUSTIC MATERIAL AND WIRE HARNESS WITH ACOUSTIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/025696
Kind Code:
A1
Abstract:
Provided are an acoustic material capable of absorbing sounds over a broad range of frequency from a low frequency to a high frequency while avoiding an increase in weight, and a wire harness with the acoustic material. An acoustic material (1) is configured by laminating a base material sheet (3) made of non-woven fabric and a surface material sheet (2) with a smaller weight per unit area than the base material sheet (3), such that the acoustic material comprises a plurality of the base material sheets (3) with the surface material sheet (2) arranged between the plurality of base material sheets (3) and the ventilation volume of the acoustic material (1) is set to within a range of 5 to 50 cm3/cm2∙s.
