One complaint many people have about the Forester is how loud it is. I'm going to see what can be done about that.
My XT is currently torn apart as I've been busy making sub kits and designing parts. Now it is time to put my car back together and I want to make it quieter while I'm at it! I'm going to document what I do and what the results are.
I'll be using the following to quiet the car:
RAAMmat
Ensolite
polyfiberfil (pillow stuffing)
expanding spray foam
Everything I do will be with commonly found items available to everyone, and I want to keep the costs to a minimum too. Nothign exotic or fancy will be done or used.
To document everything I have a Radio shack digital SPL meter. I will be using the same roads, same speeds, and same SPL meter placement to record the sound levels. It will be recorded "A" weighted with a slow response to eliminate the highs and lows and get more of an average.
Current condition:
Rear hatch interior stripped, nothing extra added yet-
Idle: 62 db
30mph: 72 db
60mph: 76 db
1st gear WOT to redline: 72 db
2nd gear WOT to redline: 76 db
Compared to RAAMmatted X:
Idle: 53 db
30mph:
60mph:
I will update and things progress...
