Building acoustic requirements for conference halls:

1.The sound quality in auditoriums, lecture halls and multi-purpose halls should mainly ensure the requirement of articulation. An appropriate intensity factor and uniformity are preferred throughout the halls. There should be no echo, multiple echo, chatter echo, sound focus and resonance anywhere in the audience halls, and there shall be no disturbance from equipment noise, projector room noise and environmental noise.

2.If the auditorium volume is more than 1000m³, a sound amplification system is preferred to be used, and the position of the loud speaker should be taken as the main sound source.
