Sound proofing

[duggram]

I've been thinking about an HDT for years and I'm just getting started as well as recently getting back to full-timing. Going through a big life change and can't do much till this is settled. But I would still like to ask some questions and do a little planning. One of the knocks I hear about non-Volvo trucks is that they are noisy. Do those folks doing conversions ever consider this? What actions do you take?

Thanks for any info,
Doug

Volvos are remarkably quiet and have been for years since the day they introduced their unitized sleeper cab. Prior to that it was "the box" that was added to the back of the cab which you accessed through a hole in the back and accordion rubber gasket. Since then every manufacturer added the unitized cab and things got "quieter". Volvo still led the pack, Freightliner was notoriously noisy. But the industry has been improving things and newer models of Freightliner are very nice indeed. Volvo still has a very nice cab with lots of "goodies". You will not feel like you are in the truck, but more like in a luxury automobile. Many truckers and gear grinders don't consider it "macho", but I will take my luxurious and quiet Volvo with an automatic any time.

I bought an '09 vovo 730 last year. No comparison b/w that and my old IH 4700. I can talk and be heard in the Volvo using normal volume. Not so in the 4700.

Your info is not correct.

It is much quieter in the cab of my 2004 Volvo than the 2001 Powerstroke I use to use to haul with.

I don't find my KW excessively noisy, but then I like to listen to the sounds it makes....after installing a high end CD player/radio in '07, I find I never use it.

Duggram I was hoping some one would answer your question instead of convincing you about Volvo, was curious as to the answers. I have heard of some folks adding sound proofing to their trucks.

[Jack Mayer]

Some people add soundproofing if they strip the cab liners down. I would if I was stripping the truck already. Even on a Volvo. Any truck can be made quiet. The Volvo and new Cascadia start pretty quiet. But there is room for improvement in either.

That is what i bought this last summer trying to kill the unwanted sounds in my Ford F-700.
I bought it cause Best buy matched Amazons price.
Its good stuff indeed. just don't pay retail.

Mekanic, how well did it improve the no sound qualities?

Well first you must understand a MDT like a F-700 ONLY has sound deadening materiel under 60% of the rubber floor mat and the underside of the
Hood when you get one. That is it. Not even a cardboard headliner like a F150 would have. mine is just painted sheet metal.

These trucks were made to driven to a work site. and that is about it.

It did made quite a bit of difference, but i still need to cover the firewall and more of the floor that i didn't to cover yet

Mekanic, thanks for the feed back

The farm combines use a two piece mat with a lead liner between them. It is very heavy but a great sound deadener. I think one could be ordered through Deere.
