Like other types of social gathering areas, the scholarship hall faces a common problem of sound reverberation that interferes with the acoustic quality of the room. When a group is talking in a scholarship hall, especially a group of hard reflective surfaces, the collective sound produces reverberation that affects the acoustic quality of the entire area. Since these reverberations can interfere with the clarity of the speech, people naturally speak loudly, creating a permanent audibility problem that can lead to an unpleasant atmosphere. Absorbing these unwanted reverbs to eliminate background noise and improve speech intelligibility is the goal of many scholarship hall acoustic improvement projects.
Implementing acoustic processing in the scholarship hall to control noise levels and improve acoustic quality involves first understanding the target sound behavior. If you stand alone in the fellowship hall and shout your name, some of the sound produced by your voice will pass through the walls and ceiling surfaces, and the rest of the sound will be reflected back from the walls, ceilings and other surfaces. When the sound is less than 0.1 second, the time between the end of your shout and the return of the sound back to the room is called the reverberation time [the time is more than 0.1 second is the echo]. Reverbs occur so fast that they are considered a long-term sound.
The sound reverberation problem in the scholarship hall can be easily alleviated by implementing a balanced combination process designed to absorb sound reflections. There are many types of sound absorbing products on the market, including panels that are fixed or suspended from the ceiling, dividing the large area into smaller areas of absorbing partitions and wall panels and coverings. Once properly handled in the team lobby, they will be used to absorb reflections and reduce reverberation time, eliminating excessive background noise. As the interference caused by excessive reverberation is controlled, the normal session level will be restored and participants will no longer need to compete with excessive noise.
The key to controlling reverberation and providing speech intelligibility in the scholarship hall is to implement adequate treatment without excessive. While it is necessary to ensure that treatment is sufficient to control reverberation based on room size and other factors, over-treatment of the room does not introduce additional benefits and incur unnecessary costs. Experienced soundproofing consultants can make recommendations based on the personality characteristics of the scholarship hall.
