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.
