Acoustic broad band panel: How to make yours

How to make a broad band acoustic panel is a much covered area of the recording environment build process.

One of the best places to get accurate information on how to make broad band acoustic panels is JohnLSayers.com

You may have special requirements that a general type broad band absorption panel may not cover, to that I offer this linked page of many types and designs of wall mounted broad band acoustic panels to better meet your needs.

Hope something fits!

Attache broadband acoustic treatments using Rotofast panel anchors for flush mount installs or french cleat for secure mounting.

From broad band treatments to bass trapping, Helmholtz baffles and vertical splayed wall treatments it just depends on the design of your room and the needs for your sonic signature.

Whatever it is that you require, contemporary acoustic treatments are the answer.

Fiberglass, Rockwool, Polyester, Cotton, and Sheep Absorption Coefficients
“Measurements are done according to a standard test method such as ASTM C423 or ISO. In some cases, the measured sound absorption coefficient is greater than 1.00. As recommended by the test method, these values are reported as measured and not adjusted. Differences in coefficients of less than 0.15 are not significant.”

“I am in the process of building several traps, slot resonators, etc. for my new home studio…and I am seeking HELP! I would like to know what everyone here recommends in the way of treating the room. “

 

Standard EN 12354-6
“Contains a method for estimation of sound absorption and reverberation time in enclosed spaces. Annex D of the standard gives a method for estimation of reverberation time in spaces where absorption coefficient varies much between the pair of opposite surfaces. “

SuperChunks bass traps: How to make
“The SuperChunk is accomplished by cutting up mineral fiber panels into triangles and then stacking them so as to fill the entire corner from floor to ceiling. Panel thickness is immaterial, but the thicker they are the fewer you have to cut, and thicker ones may be cheaper per volume.

 

The interaction of acoustic treatment in an experimental sound control room. J.A. Fletcher
“In small studios or control rooms the predicted reverberation time is often significantly different from that measured. The prediction is normally made from the absorption coefficients of the acoustic treatment and other materials as measured in a reverberation room.”

How conditioned air effects a recording studio

Your HVAC will effect your recording environment or studio so plan it out before you build.

The best thing you can do if you are building a home recording studio or home theater is to get informed about the process and to slow down. I have seen it many times. Someone starts a build and doesn’t tell anyone about it until the construction is half way over.

While this is OK for a well informed individual, it is the beginning of builders remorse for others.

So many details are involved. Much in the same way you might approach doing a room renovation or remodel or even designing a completely new home, someone has to be involved with all the details. One of the main areas people fail to consider or give the proper amount of attention to is HVAC.

A well designed room designed to hold in sound will, by the very nature of the techniques used to isolate sound, get warm. Sound isolation and acoustical treatments use products with high mass and density and many types of insulating materials.

Every attempt is made to seal the room to be free from air leaks in any direction, in any part of the room. Where air goes so can sound. It will also need fresh air. So you, as the general contractor or sole builder, must take this into consideration.

The HVAC duct work can allow sound to move from one part of the house to another. It can also be a source of sound due to moving air. This can be due to the duct material used[square metal vs. round and insulated] and the unit moving too much air into the room through smaller ducts and registers.

It is not uncommon to either have to upgrade an existing ac/heat unit or to get the newly developed room a separate HVAC unit. This is one of many areas that need the attention of a qualified technician that has experience with home theater and studio construction HVAC considerations.
