School gymnasiums are often known as one of the most challenging architectural settings acoustically. Hard and flat surface of the floor, wall, or ceiling is the main reasons for echo and reverberation.
It is hard to be attentive when you cannot quite understand what is being said. Considering the fact that gyms play host to multiple events: physical education classes, ceremonies, or even guest speeches, hearing clearly is extremely important.
So, how can we improve the speech intelligibility? Here are a few ideas
Acoustical wall panels are often attached to the walls to reduce echo and reverberation in gyms. They absorb sound waves before they bounce from wall to wall.
Acoustic Baffles/ Ceiling Banners
You could also use acoustic baffles/ ceiling banners that will be attached to the ceiling. They absorb sound and offer the same advantages as acoustical wall panels.
Line Array Speaker
Another popular way is to use line array speakers. To minimize sound reflection, which makes it difficult to hear clearly, it is important to select a speaker that is well-engineered for gyms.
Benefit 1: Reduce echo and reverberation A line array speaker consists of speakers that are positioned close to each other in a line. It reproduces sound directly toward the target area and since the sound does not disperse to any other directions, especially in the vertical direction, fewer sound waves bounce.
Benefit 2: Consistent sound quality throughout the entire audience The sound pressure from line array speaker is affected less by distance. As a result, ample sound pressure can be delivered to back of the coverage area without making front of stage excessively loud.
TOA's Line Array Speaker for Gyms
Sturdy impact-resistant (ball-proof) construction is best suitable for installation in gymnasium with adjustable mounting angle for clear sound delivery. Emission angle of the Line Array speaker can be adjusted with mounting bracket to allow the sound to travel to the back of gymnasium with minimum reflections. Example: In gymnasium with 30 m depth, install speaker in the height of approx. 4 m at an angle 0 to 3 degrees downward.
