Speech intelligibility is critical for successful teaching.  We use computer modeling techniques to predict the percentage of speech that will be understood at each seating position in a classroom or auditorium.  Adjustments in geometry and finish material selection can then be made to improve the intelligibility to acceptable levels. At the same time, mechanical noise due to HVAC sources has to be controlled to enhance the final result.  NC level predictions are made from a thorough duct path analysis and AHU siting and specification. Changes can be made to the HVAC system at the design stage to eliminate this common cause of excess noise.

Education facilities also have special acoustic requirements in the design and evaluation of gymnasium noise, cafeteria and corridor noise and dedicated music rooms.  We have recently provided acoustic design services on several major additions to Ontario universities and colleges.
