Kwam dit net tegen, interessant:

These noise-cancelling panels consist of a latex rubber membrane stretched over a 3-millimetre-thick rigid plastic grid of 1-centimetre-wide squares. In the middle of each square is a small, weighted, plastic button.
When sound waves hit the panel, the membrane and weighted buttons resonate at difference frequencies. "The inner part of the membrane vibrates in opposite phase to the outer region," says Yang. That means the sound waves cancel each other out and no sound gets through.
Maar ja, dat duurt natuurlijk weer eeuwen voor ik mijn studiootje er betaalbaar mee kan betegelen...
