Wool for sound treatment - seriously

Recommended Posts

So.. in the build out of my studio in my last home in Austin, I did a lot of research on sustainable and eco-friendly sound treatment and stumbled upon wool. Yes that stuff that suits, slacks, sweaters and coats are made from.

Inch for inch of thickness it has better performance than rock wool or fiberglass in NRC. So I built some acoustic panels using wool as the absorption medium. Works great and is lighter than the aforementioned standbys. Better in performance than hemp, which was the other alternative I was lookin at. And far less heavier than rock wool or Fiberglass.

The other upsides are the cost, it’s relatively low when compared to fiberglass (703) or rock wool. The other is handling, as there is no need for gloves or filter masks. If anything the lanolin in the fibers help dry hands.

There is a downside though. It takes about 2 years to get that sheep smell to dissipate. While it’s a mild odor it sure is noticeable.

also lambs 

Gents, not to be sheepish about it but… I prefer me lamb chops and mutton steaks without the fur on it. Thank you and Good day! Or Good night if it’s after tea.

I'm kind of used to it now as there seems to be quite a strong whiff of sheep in most places these days. I've noticed that many people have taken to wearing cloth masks to try and avoid smelling it, but haven't yet figured out why the smell of sheep seems to follow them everywhere.

You can wash it , treat it (nuisible and fire)  and play with density , i used to have a pillow made with this , since my mum change it to ergo stuff back in the dayz , i had trouble to sleep well until now in fact  ..

Not to be a downer, but any material you use for acoustic treatment should be fire retardent.

I had this first reaction as well, but wool is hydroscopic, so went to their site.

https://support.woolinsulation.com/knowledge/is-havelock-wool-fire-resistant#:~:text=Is Havelock Wool fire resistant%3F The answer is,is fire resistant. Read below for more information.

One video is no longer linked from that article, but the last video is interesting (the 3-5 minute portion is impressive). Took 2 minutes to intentionally start it, then they put it out at 7 minutes because it got boring and inspected the damage. [The second half of that video is the same test on synthetic fibers and quite astonishing.]
