Hi, I’m Currently living in the Philippines and i need to get my small studio set up to mix for clients outside of the studio i work for. I bought the BDA plans and was wondering how much more effective the activated carbon would be vs Mineral wool. I’d love to get some of the carbon stuff but im afraid shipping would be too expensive. Is mineral wool going to be relatively as effective?

P, Carbon increase the performance of each unit by 30 – 40 %. Without carbon, you will need to build more units.

Hi Dennis,
Does the denisty of the mineral wool affect the absorbtion? If so what would the ideal density be?

P, Yes, use material that has a density of at least 2 lbs / cu. ft. Make sure you wear a mask when working with this material. It is toxic.

Thats great what would happen if i used a denser material like sa 60kg/m3 or 80kg/m3? i have some of that laying around here

P, Double this density.
i’m sorry i dont quite get what you mean. Would it make it more effective as the higher the density?

Hello Dennis, I wanted to take questions for the density of active carbon
I bought the plans of the BDA and I am making the budget for its construction, what density you recommend?
Here in Brazil I meet to sell but they do not speak in density but in grain size.
And only meeting to sell in companies that sell material for water filtration, would have some other type of company that would sell the active carbon.
Thank you very much.

F, Our carbon technology is a proprietary product manufactured in our own facilities to meet the requirements of sound absorption . Carbons used for water and air filtration will not work. You must purchase the carbon from Acoustic Fields.

Thank you for the quick response.
Where could I get this kind of active carbon?
I was not that a specific activated carbon.
12
What would be the best way to talk about purchase and shipping value?
To see if it is viable to buy and send to Brazil.
Thank you

C, We ship to Brazil all the time. Send me your ship to address and contact cell number to: info@acousticfields.com

Hi denis, is carbon tecnology still available for the bda?

Hi Dennis i finally got around to star building these absorbers by myself. Should i add some glue to the mineral fiber to stick to the MDF face or just let it lay there with the 25mm gap between it and the cloth? also would 80kg/m3 or 60kg/m3 be okay to use as the dampener on the inside and absorber on the outside or should i use something denser?

J, You can use glue but mineral wool destroys middle range frequencies using over absorption at the wrong rate and level.

Mr.Foley,can You please tell as the `right` density for the replacement of the activated carbon and i really understand that it is a unike technology and that can not be replaced or imitated with some cheap Rockwool panels et.,,but should density of 60kg/m3 or 80kg/ will `do the job` or maybe 120kg/m3…150,160,200 i am really stuck?!
p.s. Also in my country there is no pegboard,i have maded at least 10 to 15 phone calls to different places stores and manufacturers and they dont have it nor made it.Just metal boards,no MDF or HDF or wood etc….soo i must make a couple of them myself..yeah great!
Thank You!

M, You can use 200 kg / m3. Metal boards will work. make sure perforations are min. 6 mm on 25 mm centers.

Oh,Thank you so much Mr.Foley i appreciate it.Can i e-mail you if anytime i decide to purchase activated carbon ..i guess deliver from London ?
Thank You
