Sound deadening

[dgrinnan]

Any suggestions?  I applied some sound deadening matts to the floor and half way up the firewall of my 47 WC.  It didn't make a real noticeable difference.  Next I was thinking the doors.  Do you apply the sound deadener to the outside door skin or the inside door skin/panel?  Where else besides doors?  Will it really make any difference?  Truck is pretty much original.

invest in a better stereo system...

Many think its about surface area coverage, or thickness...reducing noise is an art form:  right stuff in the righ place.  My B series only has the floor covered and a JUTE firewall coverage.  Not much else and I can talk just fine with the windows up.  You will NEVER get to the levels of a modern vehicle...millions of dollars spent there.

Agree with ggdad; acoustics at a minimalist level comes down to braking up harmonics and wavelengths, and acoustic dampening panels need not be full size compared to the panel they're treating.  Firewall is always a plus, some floorboard action, back wall behind the seats, roof, inner door panels, it's all cumulative, yet with strangely diminishing returns.

 

Quiet Ride solutions has both kits and individual pieces (deadeners and reproduction panels) for the Job Rated pickups and trucks (other eras, too, such as Pilothouse, Power Giant, and more), have a look at their offerings and perhaps that will help guide your decisions.

The middle area of a smooth sheet metal panel will vibrate the most, so whenever I have applied insulation, it is to these areas:  inside back of cab, inside doors, between headliner and cab.  Do not discount the area above the firewall behind the dash.  Complete coverage of the inner firewall and cab floor really helps.  Keeping engine noise down is good, but eliminating the drone from the engine and road during highway excursions is beneficial, especially for those of us who have sustained hearing damage.

The foil-faced jute from Quiet Ride is really nice. 

 

The floor in my truck is Dynamat, jute, rubber floor mat. The jute makes a big difference. 

 

Don't place anything that will absorb water in the doors as this is a wet area. 

 

The jute on the floor can also be a problem if your cab leaks (like mine). So I have to place rags to intercept the water before it can soak into the jute.
