Sound enclosure for a really loud blender??
« on: September 17, 2014, 11:53:46 AM »
I have a vitamix blender that produces about 95+ db depending on what I'm blending.  I also live in an apartment building so keeping the noise down is a big concern for me?

I'm looking at making a sound enclosure for it and was wondering what material would be good (as well as keeping the price down)?  I think MLV or some sort of soundproof composite might be good if I can find them in small quantities.  Also, having visibility at what I'm blending is key so it would be nice to have something like the transparent MLV that I've seen.

Do you know if all sides would need to hand this material and is a 100% airtight seal required??  I read somewhere that if I decide to go with MLV, hanging it rather than keeping it taught would be better at keeping the noise down.  Is this true?  If so, would it be better to just have something like a sound curtain hanging at the sides and a rigid section at the top and bottom?

thanks in advance

They already make enclosures for these blenders.

I have never done one of these but you can try..

If you want to make your own you can try to make one with our clear vinyl .160
you must be able to create seals if not the value of the enclosure will greatly be reduced.

Randy,

Thanks for the reply.  Actually, I already have on like the link you poster.  Doesn't really do that much good for reducing the sound though (only about 5-10db reduction).

Is it better to drape the MLV (provide a limp curtain like barrier as opposed to a stiffer section)?  Would this be better than something rigid like the composite sections?

Well, 5db-10db is actually over a 50% human perceived reduction so thats not to bad for some plexiglass...
The MLV drape will give you a few more points but it will come down to the seal..

Unfortunelty I do not have enough experience with additional soundproofing with these enclosures to know how much more reduction you could see....your going to have to do some experimenting.

I'm thinking of adding a layer of clear MLV on top of the plexiglass or possibly sandwhiching it between another layer of plexiglass with MLV.   I've seen some soundproof window panels used in studios with double pane glass.  The only thing is that there is a thick gap between the dual layers whereas mine would be really thin since I'd like to keep the size down.   Do you happen to know if the thickness of the gap between layers is a significant role?  thanks for your help

If you can make a second enclosure with a minimum 1" gap that would be a huge improvement.
The greater the air gap the more the reduction.. normally for maximum reduction we normally shoot for 3" or greater...

I think the gap will out perform the sandwich idea.
