Budget Horn Deadening

**mah** · February 2nd, 2011, 01:33 AM

I made a cutting template for my WURTH sound deadening sheets out of an offcut of sheet vinyl flooring called PEGULAN. This material is limp and conforms easily to the horn bell contour.
I placed the completed template into the horn bell hollow and thought I would give the mouth a tap. Well 'bugger me'!, as we say down-under, the horn ringing was almost gone. I am sure that with a suitable adhesive the result would be even better. With another piece in the underside bell I think a satisfactory result can be achieved for little outlay. There are spray can products that adhere to vinyl and others that change the colour of vinyl.

Give it a try and let me know what you think.

Cheers, Marshall

Yeah, inexpensive vinyl flooring is a cheap/easy way to damp stuff. When appropriate, I recommend using the peel n' stick squares to create a ~constrained layer damping system and for serious damping, thick commercial rubber tiles or sheeting bonded with a lossy adhesive.

I was thinking of dragging mine down to the local automotive pick-up spray-on bed liner outlet and give that a try...

I'm guessing that may be too ridged. I'd love to be proven wrong though, as I think it would a good looking and very durable finish.

Well, any sort of mass loading is good WRT metal horns, so probably as good overall as Aquaplas if applied a bit thicker.

There's always the old DIY method of mixing sand into paint and applying as many layers as it takes.

Well, I just tried thumping a pick-up with Rino bed lining and it rang like a bell. How about Plasti Dip?

In one of Altec's cost cutting measures near the end they used car wheel well undercoating water-rustproofer/sound deadner. As Aquaplas is real expensive,undercoating is not.

So you can go to your local auto parts store, pickup a couple of cans and spray it on,just mask off areas (Masking Tape) you don't want to cover.

The coating is black someone else told me about that too.That the OKC plant used Automotive Undercoating to dampen their 511E's.I'm pretty sure it was Phil Brennen eBay Moniker (aaokc)

Have no idea what you guys are using ? But all the undercoating I ever used hardened.Now if it was gummy every stone,pebbles,debris on the road would have stuck to it,not ideal for your car,let alone your horns :-) .Gummy Really ?

It's not thick enough for most stuff to stick in it.
