Sound Deadening metal

Dec 29, 2010 8 Replies

I was killing time at the Ford dealer getting the air bag system repaired in my new to me car and I saw a display of why their truck is better than everyone else's truck.



They had a sample claiming sound deadening metal and a small chunk of rusty looking sheet metal labeled competitors along with a steel rod to strike both. Well no chit, the competitors made noise just like I expected. The Ford sample didn't but there was a partial bend in one corner so I wonder if that was a trick.



Thoughts?

Lead works great for sound deadening.

Really? Every time I play with lead a loud bang follows ;)

Time to tune up the motor on your fishing boat, if it keeps backfiring like that... ;-)

I gotta buy a boat first. I keep thinking a square transom canoe with an electric trolling motor so I can go up river and float back would be the ticket. It would be something I could tow it behind my Ford Focus.

No, it wasn't.

Y'know that sticky, butyl rubber/cork-based crap they used to wrap around evaporator lines for the auto air conditioning 30 years ago? Stuck to a piece of sheetmetal and then stuck on a door panel, it deadens that door panel. I'm sure there are dozens of new acrylic bonding agents which do the same thing nowadays.

But any spray or sticky treatment means that any dents in the panel will generally require an entire panel replacement. It's not cost-effective to remove that sticky stuff since it takes so long.

You are probably on the right track with this. The better quality stainless steel sinks use some tarry sticky stuff underneath to absorb the sound from dripping water.

From what I understand, spray on undercoating works to damppen sound also.

ll no chit, the

but there was a

VW used to put what was called "tar boards" on the floor pans and in some of the doors on the air-cooled line back when for deadening vibration. It worked. Not much has changed except the materials used.
