Re: [DML] So let's quiet this baby down...

[Peter Lucas <lucas@xxxxxxxx>]

N.B.  The following is wild-ass speculation:

The biggest challenge in producing a quiet DeLorean is the fact that 
the engine is sitting 12 inches behind your ears.  Sound deadening 
material is only going to help so much.  So here's a thought:

The 2005 Honda Odyssey uses active sound deadening to quiet the engine 
noise caused by the variable-cylinder engine scheme that this vehicle 
uses. This works basically the same way as those expensive Bose 
headphones:  A microphone picks up the ambient noise coming from the 
engine, a processor generates the exact opposite waveform and feeds 
this "negative noise" into the stereo system.  The two waveforms meet 
and cancel each other out.  Works pretty well (I took a test drive on 
an Odyssey that wasn't prepped yet and had no power to the 
stereo--didn't show well).

So, maybe one could buy a pair of Bose noise-canceling headphones, 
position one of them in the firewall somewhere so that it's microphone 
picks up the engine noise, and feed the output into your fancy new 
sound system.

Probably a long shot, but would be fun to try.
