  • Patent number: 7770693
    Abstract: An acoustic equipment mat is formed by arranging plural grain pieces of inexpensive silica gel in a single layer. When the mat is disposed under an acoustic equipment, the grain pieces have their upper ends in point contact with a bottom or the like of the acoustic equipment and have their lower ends in point contact with the underlying floor or the like. Hence, the mat 1a is notably reduced in the area of contact with the acoustic equipment or the like, so as to reduce the reflection of vibrations. In addition, the mat 1a is capable of extremely quickly dissipating, in the atmosphere, the vibrations directly propagated to the upper-end side thereof and the vibrations indirectly propagated thereto as reflected by the lower-end side thereof.
