Building a frameless broadband absorber

[mikeperaltamusic]

You know what I just realized would be so awesome? A dedicated video showing how your videos sound before and after adding these for treatment, with an explanation of why they change the sound, how, and why that is desirable..

Rockwool 80 is the recommended one ? is it cheaper than OC703 ?

[franguidry]

@zzzxtreme Sorry, I know nothing about Rockwool 80 or the recommendation mentioned below.

the panel is to hard to not bounce the sound

[franguidry]

@bradhammett1 Thanks for offering your opinion. I wonder how you developed your expertise? The compressed fiberglass I use is one of the most widely used sound treatment materials available, it's the basis for nearly all the panel absorbers on the market.

@franguidry

The market has moved on since then they found that the fiberglass was having to be 80kg non compressed, with a metal pin holing it in place but then the slab gathers at the bottom of the fabric. So the company that i work for and is in the tender for the new pinewood studio's, have been found a Rockwool 80 work for year's longer and held up.

the funny thing about this technique is it defeats the purpose of the trap. when spraying an adhesive like that anywhere on the compressed fiberglass or rockwool, it fills in the poors with glue. thus not allowing the sound to enter into it and being trapped.

[franguidry]

@vinylredstudios Thanks for your input. I just tried blowing through the glass and could easily exhale through the fabric, glue, and fiberglass. Since sound is air motion, I believe this demonstrates that you are incorrect, but I'd be interested to get more info.

@vinylredstudios Ahem - sound travels easily through doors, ceilings etc - think about it. A little glue will have littel to no effect.

thanks for video

[JeimusuJones]

Thanks for the video. Wear did you get the fiber glass panels?

[franguidry]

@JeimusuJones I bought them from a local wholesale insulation supplier. Please visit the Homebrewed Music blog and check the article, it has the info on the vendor. YouTube comments don't allow links.

preciso apresentar um seminario sobre absorvedores e refletores de som.

acho que isso ajuda.

How do you hang it to the wall?

[BluePaisley]

@wakena2003 - I don't know how he would hang it... But some people just 2 screws in the wall leveled, then use D shackles attached to the trap and hang them on the screws... Of course that requires making holes in your wall! Velcro is another option, but since bass traps are usually in the corners it can be a little tricky! Either way you generally don't have them flash against the wall because it will only do half of the job you do need a bit of space behind them.

@wakena2003 Oops, sorry I missed this one. I straddle vertical corners with two panels which fit nicely from floor to ceiling. I straddle ceiling to wall coners with eye hooks and twine. I also use eye hooks and twine to suspend panels from the ceiling. Then I lean the rest against the wall so I can move them around if needed.

i think your fabric its too thick you should use polyester, if you can blow air easily throu the fabric sound will pass freelly so it improves other wize it reflects mids and highs its just a tip .!!

[homebrewedmusic]

Thanks for visiting. Burlap is a standard covering, it's not a very tight weave and passes air very easily.
