Nowadays, many schools will build auditoriums, especially multi-functional auditoriums. Their main purpose is to do some theatrical performances or report conferences. If it is a theatrical performance, it is generally necessary to set up a fixed stage on the side of the venue for conferences. In addition to the dedicated lighting system and language broadcasting sound reinforcement system, the electronic equipment involved in the podium and performance venues of theatrical performances must also be equipped with stage lighting and a sound reinforcement system for theatrical performances (both language and music). And so many electronic devices will have a certain impact on the sound field of the performance, so acoustic design is needed at this time.
The indicators and requirements of auditorium acoustic design are as follows:
The acoustic conditions of the multifunctional auditorium should be based on ensuring clear language, and no obvious sound focus, echo, tremor echo and other sound quality defects should be produced.
The glass windows around the multifunctional auditorium should be equipped with sound-absorbing curtains, and the large area of the wall should be treated with sound-absorbing treatment. If it is not used as a theatrical performance, but as a multifunctional conference hall for conference reports, it also needs to be a multifunctional meeting. Hall sound absorption treatment.
Acoustic defects in multi-functional auditoriums usually mainly include two problems: one is the long reverberation time, and the other is the presence of serious acoustic focusing and flutter echo. It is not too difficult to solve the first problem. You only need to add a proper amount of sound-absorbing materials in the hall (make full use of the walls and ceiling), such as: auditorium sound-absorbing panels, which can shorten the reverberation time. The difficulty is the accuracy of the design calculation and the rigor of the construction process.
The greater difficulty in solving the acoustic defects of the multifunctional auditorium is how to eliminate the serious sound focusing and flutter echo caused by the irregular shape (arc vault or round wall). Without changing the overall shape, appearance, lighting function and architectural style of the original architectural design and decoration design of the auditorium, this is the most challenging and creative key to the acoustic design of the auditorium.
