Dear Forum, I have a home studio that I use for doing sound design for theatre, mixing acoustic theatre (theatrical installations and radio drama) and composing electro-acoustic music. I'm gradually diminishing the reverb in the room and I'd like some advice please on further steps I can take on a low budget (we renovated this house recently so I'm doing things slowly!).

Hi, here are a couple of pictures of my recent ceiling treatment project. My recording/rehearsal studio was too dead, and I decided to install some reflectors/diffusers to liven it up a bit.
A full writeup, including some sound samples, is at www.cloneensemble.com/diffusers.htm.

Room dimensions - 14' 6" L x 12' 3" W x 7' 11" H
Construction material in room: old plaster walls, to my knowledge, no insulate material of any kind on the inside of the inside walls, OC R19 on the inside of the outside walls
2 windows,

Hello!

Hello everyone, my name is Gianluca and I'm writing from Italy.
I turned a basement into a recording studio, but I need a hand to the acoustic treatment.
Floor, ceiling and walls are covered with wood. Under the wood there is a layer of lead, polystyrene and moisture resistant material.
The dimensions are:
Length: 4m
Width: 2.56mt
Height: 2.7 meters

Hello all,
I just bought 9 pieces of rigid fiberglass board, 3# density (Johns Manville 814). 24"x48"x2".
I have lots of acoustically transparent burlap to wrap the panels in, and mounting hardware, for walls, corners, and ceiling.

Looking to treat my room, but I want it to be safe for health. From just breathing it (even if uncovered), handling it and in case my dog accidently eats some of it.
What kind of material would be what I am looking for. Safe and non-toxic, yet a great sound absorber.

Looking to acoustic treat my room. I want to get safe, non toxic acoustic treatment that still has good sound absorption. Looking for the material wise, since different pieces would be used for different frequencies. Want it safe to breath (even if not covered by fabric), also safe in case my dog accidently chews and swallows some. Also safe to handle.

Guy in area is selling his "high grade, high density professional acoustic foam"

And the 3 in. thick 2 ft x 4 ft panels for $17 each.

Hello,

I'm looking for some help/validation with a few sound issues we've been having in our church.
