Here a few considerations to think about when designing a Conference Room.
- Recommended reverberation time is between 0.6 and 1 second.
- Absorptive materials will most likely be necessary for the ceiling. Often times, the perimeter of the ceiling is absorptive and the area above the conference room table is kept reflective.
- Even if the reverberation time is optimally controlled, reflections from the walls can be problematic. Slap back from the back wall can create an issue for the presenter and parallel reflective surfaces can cause an annoying condition called flutter echo or standing wave. Ideally, at least the back wall and one side wall should be treated with acoustically absorptive material. It might not be necessary to completely treat the wall as long as the critical zone (normally from 3′-7′) is treated with a material that has an NRC of at least 0.50, ideally at least 0.80.
