The goal of acoustic design is to create a space and provide good acoustic conditions for people. Activities ranging from speech performances to acoustics and amplified music. The multi-function hall is designed to be used as a multi-functional space. The design of multi-function hall is mainly concrete structure. This must be considered in the acoustic design and material selection to ensure adequate sound absorption at low frequencies.


If the number of spectators in the room fluctuates, what impact will this have on acoustics?

Generally, as the number of seats increases, the room tends to become wider (rather than deeper) and fan-shaped to maintain the stage size and line of sight. However, this shape usually has a serious impact on the sound quality, because a wider angle will reflect the sound to the rear of the room, rather than the audience, or delay the arrival time of the reflected sound. The direct sound from the performer to the listener is straight, without reflection. The sound reflection arrives after the initial sound, and after it bounces off the wall or reflector, it arrives, much like the echo in a cave. Geometrically, this is because the reflection must reach the initial surface, reflect from the surface, and then spread to the audience. The reflex is farther away from the listener, so it arrives later. However, the reflection must arrive within a short time of the initial sound to be understood as useful information for the human brain: for human voice, within the first 50 milliseconds, for music, within 80 milliseconds. The sound that arrives after this time will reduce the audibility of the voice or the clarity of the music.


With the continuous development of customer design requirements, there are fewer and fewer single purpose venues. The economy of operating a venue almost always requires multiple sources of income, which means that multiple groups use the venue in different ways. Although the demand for multi-purpose venues has increased, these spaces must be carefully designed. Otherwise, the space is only suitable for one purpose, which leads to the poor practicability of other purposes.

A successful multi-function hall, which supports many purposes. Such as music performances, gatherings, large parties, concerts, lectures, etc. Its design is both beautiful and practical, and will become the most practical hall in the area.
