Being a Discovery channel addict , a few months ago I remember watching a programme about counter acting the noise in an aircraft cabin. I didn't fully understand it , but basically a computer controlled gizmo created a noise opposite to the noise in the cabin which led to the cabin noise being cancelled out !
The result was spectacular and better than any amount of sound proofing could do in a prop plain. I would like to think that this technology would eventually become economically viable to use in a car ! Or better still my living room :-)
For now , I will just turn the radio up a bit
