Electronic drums can be played without external sound using a pair of headphones but the act of pressing a pedal can still cause unwanted disturbance. Placing the unique rubber dampers under each leg of a kick pad and hi-hat stand dramatically reduces the transfer of noises and vibrations through the floor.
Roland has been testing a new product called the Noise Eater which uses unique sound isolation techniques specifically for use with V-Drums to significantly reduce noise and vibrations to rooms below. This never before seen video provides an inside look into that testing process. NE-10/NE-1 http://www.rolandconnect.com/product.php?p=ne-10
