Reverberation is a common problem in schools. The use of hard materials allows sounds to bounce off easily, resulting in poor acoustics. Because of these poor acoustics, audibility deteriorates, requiring teachers to raise their voices to make themselves understood. The result? Headaches and fatigue. Students also have poorer concentration, which affects their learning performance.
Why is acoustics more important than ever?
A modern and learner-centered teaching method is being adopted today. This method combines classroom lessons with group projects. Students more often work together in open learning environments where they communicate about their projects. In these environments, one room is often divided into several separate pieces. This allows each group to dialogue with each other separately. The result, of course, is additional noise.
How do you test the acoustics?
The acoustics in a room can be established by measuring reverberation time. In this process, a sound meter is positioned and then fires a few shots with an alarm gun. This acoustic measurement takes about 10 minutes and takes place without employees in the room.
Reverberation time reduction can be achieved by absorbing or isolating sound waves. When we absorb, the sound waves are absorbed into the sound absorbing material and cannot reflect back completely. Some of the sound is converted into heat, and the rest bounces back into the room. Sound insulation involves ensuring that sound cannot travel from one room to another. Here, mass is a determining factor. The higher the mass and density of a material, the better it can stop sound waves.
What is the best way to tackle this problem?
To reduce reverberation in a room, you apply absorption material. This will penetrate and absorb sound waves. There are several solutions for classrooms. An effective and unobtrusive solution is to fit the classroom with ceiling panels. If you prefer to create smaller spaces, you can opt for room dividers or whiteboards. These are not only good for acoustics but also provide visual tranquility and separation. If you are looking for individual solutions then concentration screens placed on a student table are in place. Thanks to these screens, visual and acoustic stimuli will be reduced, allowing the student to concentrate better. Each acoustic solution is available in different colors of fabric or a fun print of your choice. This automatically lifts your classroom to a higher level.
