Abstract: An acoustic equipment mat 1a is formed by arranging plural grain pieces 2a of inexpensive silica gel in a single layer. When the mat 1a is disposed under an acoustic equipment, the grain pieces 2a 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.

Abstract: A mat (1a) for an acoustic apparatus, wherein a plurality of granular bodies (2a) of an inexpensive silica gel are disposed in the state of single layer. When the mat (1a) is laid under the acoustic apparatus, the upper end parts of the granular bodies (2a) are brought into point-contact with the bottom surface of the acoustic apparatus, and the lower end parts of the granular bodies (2a) are brought into point-contact with a floor surface thereunder. Accordingly, the reflection of vibration can be reduced by minimizing the contact area of the mat (1a) with the acoustic apparatus, and vibration on the upper end part side of the granular bodies directly transmitted to the mat (1a) and vibration indirectly transmitted to the mat (1a) after being reflected on the lower end part side of the granular bodies can be very rapidly diffused in the air.
