Sound absorption of walls – reduces echo in schools and school environments
Effective sound control with wall-mounted sound absorbers in school premises
In schools and educational environments, the sound environment is a crucial factor for both learning and the working environment. Classrooms, group rooms, corridors, and common areas are often characterized by hard surfaces such as concrete, plaster, and glass. When students talk, move around, and work at the same time, sound is reflected between walls, ceilings, and floors, creating echoes and long reverberations. Wall sound absorption is an effective measure for reducing these reflections and creating a quieter, more pedagogically functional sound environment in schools and educational environments.
What is wall sound absorption?
Wall sound absorption involves installing sound absorbers directly on wall surfaces to capture sound waves and reduce reflections in the room. The absorbers consist of porous materials that convert sound energy into heat energy. This differs significantly from sound insulation, which stops sound between different rooms, and vibration damping, which reduces vibrations and structure-borne noise from, for example, installations and technical equipment. Wall absorbers are used to improve the acoustics in the room where the sound originates.
Common acoustic challenges in school environments
Echo and poor room acoustics are common in classrooms, corridors, dining halls, and common areas. When many students are in the same room, the noise level quickly increases, making it more difficult to hear speech and instructions. This can lead to increased fatigue, poorer concentration, and higher stress levels in both students and teachers. In teaching environments where clear communication is crucial, poor acoustics become a direct obstacle to learning.
How wall-mounted sound absorbers work
When sound waves hit a wall absorber, they are slowed down and absorbed into the structure of the material. Since many sound reflections occur at ear level, walls are a strategically important surface to treat in order to shorten the reverberation time and improve speech intelligibility in the room.
Improved speech clarity in classrooms
Wall absorbers reduce disruptive reflections and make the teacher's voice clearer to students.
Flexible and discreet solution
Wall-mounted sound absorbers can be placed where they are most needed without affecting furniture or educational areas.
Interaction with other sound-absorbing solutions
Wall sound absorption works best as part of a comprehensive solution. Ceiling absorbers reduce reverberation over larger areas, sound-absorbing curtains reduce reflections from windows and glass partitions, and room dividers can be used to create smaller teaching zones with improved acoustics.
Why choose wall sound absorption in schools?
Wall absorbers provide a quick and clear improvement to the sound environment without the need for structural alterations. The result is noticeable in the form of lower perceived noise levels, improved concentration, and increased study tranquility. In school environments with more complex sound problems, wall absorption can be combined with sound insulation between rooms or vibration damping from technical equipment.
Well-considered advice for best results
For the best effect, wall absorbers should be placed on surfaces where sound reflections are strongest, often at ear level along classroom walls, corridors, or gathering areas. Larger schools often require several absorbers for even damping, while smaller classrooms can be improved with a few strategically placed solutions. A common mistake is to underestimate the importance of walls for acoustics. The right scope provides a long-term, functionally and pedagogically adapted sound environment.
Sound absorption of walls is therefore a safe and effective measure to reduce echo and improve the sound environment in schools and school environments.
