Melde's experiment teaches us creation of standing waves. I think we can create a great product of neutralising the sounds by creating sounds with same wave length and frequency as the source. ex: if you know exactly the frequency of any machine ( say an aeroplane flying over your building every day during take off and landing) and if you can measure the wave length of sounds that machine creates..create a product that can create similar waves in opposite direction.so that they undergo mechanical interference and the machine sound is neutralised.

Bingo!
