Recording, Television, Radio
Television, recording and radio studio design demands careful space planning and integration of mechanical and electrical systems to ensure an extremely low noise environment for microphonic recording. To accomplish this, several key elements must simultaneously function within the design.
For HVAC systems, air flow velocities must be kept minimal for equipment servicing critical areas. This is often accomplished by lowering fan speeds and oversizing ductwork. Careful detail and planning considerations must be made for vibration isolation of this equipment. More often than not, in-duct noise control is required to mitigate fan noise.
Acoustically, most control rooms, voice-over booths and audio edit suites are smaller in size such that they suffer from low frequency modal problems. These issues must be addressed to create a neutral mixing environment which translates into the real world. Tracking and live rooms pose unique challenges because they must provide an acoustic environment conducive for recording a wide variety of material. Furthermore, room-to-room sound and vibration isolation must be maintained at all times. This requires walls, doors, ceilings and windows to all have adequate mass to attenuate sound over a wide frequency range.
Environmental factors must also be addressed if the building is located near noise and vibration sources that could interfere with audio recording. Any disruption of recording costs the studio money, and potentially, clients. Detailed environmental surveys are typically conducted to determine the level of isolation required.
These design issues must all be accomplished within the project budget. It is not uncommon for studio designs to exceed $300.00 per square foot, which leaves no room for error.
Project Profile: WGCL Atlanta News Studio
Any studio designed for live broadcast requires very low background noise. BWS was presented with a major design challenge where we were required to provide noise and vibration control for two screw chillers located in a mechanical room adjacent to the broadcast room. Accordingly, the requirements for this space were such that it had to be acoustically neutral for the set designers. All walls, doors and windows were carefully designed to ensure privacy during broadcast with minimal “bleed” from the adjacent News Room.
