A conference hall with best acoustics, apart from being aesthetically pleasing, is a prerequisite for all offices to hold valuable communication forums that maintain greater levels of confidentiality. Conference rooms pose several sound reduction and acoustical challenges since they are single enclosed rooms where many people gather to discuss official matters.
In order to improve overall acoustical quality of the conference rooms, the transmission of noise into and out of the room should be reduced. The quality of acoustics within the room should also be improved for a better understanding of speeches and presentations. Elimination of excess noise reverberations within the room aids in improving the acoustics of the conference hall.
While designing the acoustics of a conference room, the points that need to be considered include sound bleed into and out of the room, background noise, reverberation and sound reflections. Sound bleed is the primary concern since sound isolation should be achieved in order to avoid disturbance to the people within the room due to external noise and vice-versa. The reduction of sound transmission between rooms can be achieved by isolation of the room by coating the walls with a layer of mass loaded sound barrier vinyl like dB-Bloc and/or constructing a secondary drywall layer. Acoustical tiles provide the additional sound-proofing effect.
Absorption treatments further help to control the background noise reflections within the room and thus help in improving the acoustical quality within. Sound absorptive panels also reduce the excess reverberations and produce clear audible sound. Diffusion of sound reflections supports the clarity of audible sound. HVAC system noise control is also sometimes used for the reduction of background noise. Better acoustics provide better environment for meetings and long boardroom discussions.
