Quote:Noise is power wasted

I would have thought that noise suppression would be more likely to be power wasted. I say this without prejudice to anyone's choice for their CB.

Cheers

Depending on the noise suppression, it might be or not be. Restrictive exhaust can waste power; however, if an engine is DESIGNED with back-pressure as a factor, then with back-pressure it's at optimal operation.

But back pressure is not the reason for noise suppression. The trick is to bounce the sound waves against one another, cancelling them out.

That does not recover the power, either. But the noise of the exhaust, is energy - the explosive energy of fuel combusting; noise that goes into sound instead of pressure on the pistons.

WERE there a way to put that bark out the pipes, more into usable force...it would greatly increase efficiency. In any event...I don't equate power with noise. To me, an un-muffled or Cherry-Bomb equipped car or cycle, makes me think of callow, thoughtless, inconsiderate youths who probably own the noisemakers.
