There is a possibility that our organization is moving. As the A/V production Specialist, I've been tasked with compiling a list of requirements for production requirements in the 'possible' new location. (yeah, time to put in for all the toys we didn't get in the last budget).
Anyway, I would like to query the pro's in this forum about the exciting world of HVAC air diffusers. I want to make sure that the new studio space will have adequate ventillation, but am concerned with air flow noise. I've asked for 14' ceilings but was wondering if anyone knows if there are 'silent' air diffusers, and if so, where might one look to aquire such items.
OR - if you have any suggestions on how to minimize the impact on taping sessions, I'm open for ideas.
HVAC problems normally boil down to compressor/heat pump, fan and duct noise.
If the air handler, heating and cooling stack is in the next room, you better have good construction so you don't hear it through the wall, or up over the wall though the ceiling.
Duct noise is about the size of the supply and return ducts, whether they are lined, and whether or not noise blocking panels (diffusors) are built in to the duct to reduce the noise in one room from being conducted up through a vent, down a duct and to another space.
Air noise itself is also an issue. The smaller the ducts, the louder the sound of air running through them.
Good HVAC design for "quiet" areas requires attention to all of these areas. Licensed HVAC installers may not have experience in designing or installing a "quiet" system correctly. For the best results (and boy are they worth it) you may need some extra help in designing and installing. I mention both, because I know of correctly designed system that were improperly installed. The result? Noise.
