Road noise is my biggest complaint about this car. I have not yet tackled the issue but I am very interested in any responses here. Thanks for telling us about the improvments you made to the rear of the car. I am going to start in the front.
Please keep us updated. I'll try to do the same if I do any other areas. I suspect the floor is main culprit.I am going to start in the front.
So would not putting some sound absorbing material in the spare tire well do any good?I thought I remember reading somewhere that the spare-tire well transmits a ton of sound. I also think the front wheel wells are light on insulation. Wish I knew someone that could do it for me.
Sound absorbing material is only one part of the equation. The first step in noise control is to minimize panel resonance caused by vibrations transmitted by the engine, exhaust, suspension, and road. The spare tire well in the CT is a great example of panel resonance; the well is effectively a speaker and transmits noise. The solution is to add vibration dampening, which can be done with RAAMat or other similar products. You could attempt to block the transmitted noise with sound absorbing material, but you'd need so much of it (in terms of thickness), that you'd end up reducing the interior capacity of your car.So would not putting some sound absorbing material in the spare tire well do any good?
This = winner; what kind of SSA stuff?To BLOCK noise from coming in you need a mass loaded barrier. Such as MLV
The dynamat/raamat/damplifier is used to absorb vibrations
Will damplifier block some outside noise? Yes. Will it do so as well as MLV? No
Also I have used all and I will only use second skin audio from now on.
I have a bunch of SSA stuff on order for my upcoming CT200 SQ install. I will post plenty of pictures !
Good luck with the surgery gs. Drop in a line about your progress, and wish you a speedy recovery.I have just done the rubber undercoat on the wheelwells as well as the spare tire compartment. Unfortunately I am going in for knee surgery tomorrow and will be unable to drive for about 10 days. I will let you all know how it goes when I get back behind the wheel.
