Do you think it will outperform DP per area thickness, then? I mean, if you can make a VE damping product that doesn't **** in the cold, that's pretty sweet. Many complain of heat, but my car SUCKS in the winter. So depressing. //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif And thanks for the offer.
I think that if you want similar results from the Spectrum you will need to apply it about 20% thicker than the Damplifier Pro.
No foil and different viscosity and elongation means different elastomeric value and different range of frequencies will be treated.
In car audio applications it is not nearly as important as.. lets say.. someone trying to quiet down a street rod from loud exhaust noise and tire noise. That requires more attention to detail with repsect to which product you use, how much, and the location it goes in the car.
In car audio application the main goal is simply to kill the audible vibrations keep the energy in the car. Mostly.
This is pretty easy to do, The range of musical frequensies effecting the sheet metal is pretty limited. 10 hz -1000 maybe..
Weather you use Damplifier Pro or Spectrum, you will certainly address those resonating frequencies. How much of them you address depends on a few things.
-Elastomeric value (effected greatly by temperature)
-Energy conversion- part foil thickness/strength, part adhesive considerations
-Total Weight - not as important but a good guage for value
Temperature is somthing many people do not take in to consideration as well.
The more stable we can keep the adhesive the wider the damping curve gets.
Here is an example.
Load up your car with a CLVED
park it in the sun for 4 hours
turn up the volume and burp your best test tone
Mark your score
Then par the car in an airconditioned garage for 4 hours
turn up the volume and burp your best test tone
Mark your score
Mostly likely you will hit higher numbers with the cooler car.
Elastomers get soft when they heat up. This changed the curve and thows everything off.
The more stable we can keep the product over a wider range of termperatures, the most consitant our damping results will be at different temperatures.
so in closing...
Don't punch babies..
