Has anyone played around with the best approach to reducing the noise in the cab. Specifically placement of the sound deadening matt products. Have you found there are certain areas that seem to have the biggest impact when applying the sound matts or should I just plan on pretty much applying it everywhere? Obviously time and money are factors. If not, just cover everything.
floors?
inside doors?
cab walls?
cab roof?
every possible surface?
I also used Dynamat pretty much any where I could. It really keeps it from sounding like a rattling tin can. Kind of pricey but easy to install. I did inside my doors as much as I could reach. I did a short video on YouTube one with and one without where you can hear the difference closing the doors. I’ll come back and edit to add the link but if you search my name Donald Sessum you should see it.
