You can silent practice at your drum kit, without having to worry about complaints about the drum kit and cymbal noise. Complaints about your drum playing ability are up to you to fix, so get practicing quietly. These drum set percussion practice pads are rubberised discs and the centre section responds to the drum stick with a similar feel & bounce as the actual drum head. The practice pad set reduces the sound output of the drum set and cymbals by approx 90%.
