MKX road generated noise vs exterior free air noise.
One of the problems I found with recent Lincoln vehicles especially the MKX series vs older Lincoln’s (Mark VII & VIII and Town Cars) is the fact that the MKX does a fine job of eliminating outside sounds (at least mine) such as free air sounds (traffic & wind). The new laminated glass in the side windows has helped this. But my biggest complaint is the amount of road generated noise that is transferred to the vehicle from the tires. This is especially a problem for us owners of low-profile tires as the sidewall is just too short to help absorbed some of the road roughness that transfers to the body as road noise. Older Lincoln vehicles used massive amounts of mastic and padding under the carpet to insulation and contain this body noise.
The designers at Ford Motor Company did a fine job on the design and execution of our vehicles. But then the bean counters got involved as to where to cut costs. If you take a look at the carpets in our vehicles its just thin and cheap and so is the thin padding underneath. I’ve seen apartment grade carpeting that’s of better quality. Under the carpet and padding is the floor pan and Ford did apply mastic in some areas to help control the resonance in the steel, but it’s just too little to do a minimum amount of sound control.
A couple of weeks ago I removed the front seat, carpets, and Styrofoam inserts and lined the floor pan with a product called Dynamat. www.dynamat.com You cut the sections and then remove the paper backing and the Dynamat sticks to the floor pan. I then replaced the Styrofoam inserts and over this I applied a product called Dynapad. Dynamat stops resonance and Dynapad stops sound. Dynapad is 3/8" four layer composite sound barrier. I then replaced the carpets and seats.
I would say there’s 75-80 percent less noise now. I’ve only done the areas in the toe board and under the front seats but I plan on doing the rear carpet area, under the rear seat and cargo area.
Now if “The Lincoln Motor Company” would only spend a few more dollars per vehicle to contain the road noise we could all say once again, “Lincoln, What a Luxury Car Should Be”.
This is the first time in the past nine months that I’m really starting to enjoy this vehicle.
Finally got around to getting some photos for all you to see.
