How much power would it take to make an open exhaust quiet, like those Bose sound-cancelling headphones do? Just one of those pie-in-the-sky ideas that occur to me every once 'n a while--I wonder if the power to do it and the weight of the system would hurt more than the open exhaust helps.

 

Although not impossible, it isn't a plausible idea. The way headphones work is by sending out a signal that has the same pitch as the sorrounding sound, hence canceling the sounds out. However, of the ambient sound is out of the headphones range, you will still here the noise, just at a lowered level. So for exhaust, there's no way to cancel noise like that...Well not no way. The system has to be pretty powerful, and be able to withstand the heat from the exhaust. I just dont think its a good idea after all.

 

easyer, if you buy those bose headphone's for the cop's...
