Can you use a sound pad to completely cover an electrical outlet?

Would this a be a code violation to completely cover an electrical outlet to reduce sound transmission?

I'm looking at this product and I don't see UL or other lab listing.

It doesn't cover the front.

It is almost identical to fire proofing boxes. Sound proofing is grey and fire proofing is red. I am guessing there is some chemical difference but looks the same.
 
Looks like this product doesn't have a UL listing - is one required?

I'm assuming for sound transmission it's not required. But if you're using it for a fire resistance then it it's required.
 
The only thing that looks sketchy to me is that the photo of the 4 square box has knockouts punched and then covered with this putty. I doubt the putty is considered an acceptable knockout filler :)

I don't see why the putty would need a UL listing any more than plaster around a box. If the material gets _into_ the box it might be a violation of the box listing, and putty that interferes with the installation of a connector might violate the listing of the connector. But putty on the outside of the box is not an electrical issue.

I agree. I used the fire rated ones (had them left over from a job) for sealing the box openings which helps in mitigating sound transmission when I built my home guitar studio. 1000000371.jpg
