I work at a chemical company where we are constanly evaluating process noise and the need for hearing protection. Noise levels above 86 db long term can be damaging.
I took someone for a ride in my car and he commented on the high noise level, rained on my parade. I then took the comany noise metter and started testing and found it was quite high. It was close to 86 at idle. I was able to reduce the level by applying Dynamat material under the rear seat and engin wall, reduced the level to 96 from over 100. One major contributer was installation of stainless steal heat exchangers, should of replace with normal steal.
For a long time I wore foam ear plugs, but eventually got rid of the car primarily because of that. Loved that car, hoping the Boxster will give me similar enjoyment.
