Re: Noise Control



Dave - First off, I find the noise level in Winged1 to be akin to 
"music to my ears", especially at WOT (wide open throttle), but that 
is certainly a personal preference for everybody. I know that several 
PNDC members have applied noise-suppression material to the cargo 
shelf, and also behind the "back wall" panel between the rear cargo 
area and the engine compartment. The cavities in the underbody can 
create the effect of a bass resonator, so packing those cavities with 
sound absorption material can make a significant difference. One 
member added some material to the trunk area under the carpet, 
and noted that the resonance from there was improved. Also, several 
folks on the DML have talked about noise coming up from the shifter 
area, and through the center console in general, leading them to 
adding sound proofing there as well. The rigid underbody is a very 
effective "noise transmitter", so if anything that generates 
vibration is touching the underbody, it will be carried very well into 
the cabin. Take a look for anything touching or riding on the 
fiberglass which could generate noise. You just have to keep adding 
stuff until you reach the level of "acceptable noise". Or ... turn up 
the stereo another notch or two.

completely rip out all of the carpet and put down new 1/4" layer of 
closed cell sponge rubber and new carpet padding. This made a vast 
improvement on the road nose but the engine noise is still unbearable.
