Inquiry (采购产品): Floor isolation Hi, I own an electronic drum kit. when I hit the bass drum using my foot on a pedal it creats vibration to the floor and my downstairs neighbors hear every kick. (Its like hitting the floor with basketball). I'm using plywood+carpet but it's not enough. Do you have any solution for 4x4 ft. area? some surface or rubber tiles. If so how much does it cost and where can I buy it?
