Is there a simple noise cancelling system for a car?

One of Hurtubise's latest projects has been the creation of a new paste that he's called 1313 and believes could be put to good military use. It is a mixture of all his previous concoctions applied to a kevlar fiber pad and then subjected to high pressure for the period of a day in a press. The result is a board or tile-like panel. The panel is placed in layers with other materials such as tiles. The resulting composite material can withstand a direct assault by shotgun slugs, rifle fire, and enough high explosive to demolish a car, yet is quite inexpensive to manufacture. At an enthusiastic demonstration taped by Daily Planet, Troy displayed its capability to a Canadian military observer. In one of Troy's demonstrations, the composite material was placed in cushions meant to be placed over the outside of a Humvee. In the tests, the material successfully blocked explosive charges greater than those of a rocket propelled grenade, and was able to block shot after shot on exactly the same point of impact by a sniper rifle (which is a feat no material in use by the U.S. nor any other military has matched in public demonstrations). It is Troy's desire to see military vehicles, currently in service in Afghanistan, equipped with such protection in order to stand up to a landmine explosion, which has already claimed the lives of Canadian soldiers serving there. That, along with his younger brother serving in the Canadian military, inspired the creation of 1313.
