It's called Dynamat and it's typically used in cars for noise control for audio systems. They guys who installed my granite counter tops told me about this when I was asking them what I could do to deaden the drumming of running water in the kitchen sinks. I got it at Best Buy. It comes in a one foot square sheet. Just cut it into strips, peel off the backing, and stick it on the underside of your sink. No more irritating noise.
