As most of you know, the Freightliners are rather noisy, so as a PhD in acoustics, you know it has driven me nuts. I have a new acoustics manufacture that does vehicle dampening as well. If anyone is interested, I will log the progress as well as the good and the bad. So far all I have done is take the interior out of the cab. The dash is next. I am installing three different types of acoustic dampeners.
1) sound barrier on the floor and fire wall
2) vibration dampeners on the doors
3) sound absorption inside of the dash
I'll post some pictures if it all works. My company does acoustic control for buildings, so this is kind of new to me.
