3M noise damping tape

Cool didn't know the tape existed.
Many uses come to mind.
I see it in my next turntable episode.

This is nothing new. I could have used duct tape on my ex's mouth and prevented a divorce. Yet on the other hand...what am I thinking?? Naaaah, good riddance. 😁

This reminds me of the sound deadening I use when modding cars. A similar idea. but in tape form. In fact, tape like this could come in handy for problem areas where thicker sheets are not as easy to install.
 
Ooh this is neat. The underside of my Empire top-plate has a lot of Dynamat on it, but this would be an easier to use and less-messy option. It could also be used on the platter without throwing off the balance as much, though I've damped that by using a multi-layered heavy mat on top of the platter isolated by a felt layer.
 
I checked locally for the 3m tape. It would be perfect for my Luxman tt. A number of locations are listed by 3m that should have it; only one has it on a website. And that one lists it in a box of six, and that you must request a quote for it. I think it's $80+ per roll.

There's some on ebay. At least I think its the same stuff.

 
Works really well. Great for chassis damping. I like that it's fairly thin. Probably going to try it on parts at the component level. Going to be just the stuff for speaker drivers (frames, magnets,etc.). Will try it for speaker cabinet damping, but I usually use generic dynamat type sheets.

Also, going to give it a try on my next turntable build.

How would this stuff work taming the resonances in hvac pipe?
I'm thinking sound dampening sheets would be more effective, provided you could get them to stick. There are some wide temperature swings between winter and summer HVAC usage. It makes a difference in cars, but only if most of the surface area is covered. Putting just a few strips on a large door panel doesn't work, in other words.

I also wonder if some of that rubber underbody coating in a rattle can would work well enough. It certainly would stick better, but the odor and fumes would be a bit much for indoor use.
 
For my "better" projects (mainly automotive), I use products from Second Skin Audio--they have a comprehensive selection, plus a lot of info on their site as to what each product does, and how it should be applied.

On the other hand, I used some of the generic Amazon-branded sheets for a budget build (another automotive project) and while they weren't quite as effective as the Second Skin products, they were still quite respectable for the cost, which is appreciably less.
