  • Surface material and method of suppressing influence of surface wave
    Patent number: 6702063
    Abstract: The present invention provides a surface material comprising a fibrous structure having a weight average single fiber thickness of from 0.0001 to 1 dtex, a thickness of from 0.10 to 5 mm and a unit weight of from 50 to 500 g/m2, and disposed on a surface of a body in order to convert at least a part of a surface wave, generated on the surface of the body by vibration of the body, into a vibration of the fibrous structure, and a method for suppressing the influence due to the surface wave. In the present invention, by disposing the surface material on surfaces of various members receiving vibration, a modulation of the vibration originating from the surface wave which greatly influences a human acoustic sense can be efficiently suppressed, and a sound quality and an image quality can be prevented from being deteriorated.
