Sound-absorbing notice boards – practical sound insulation for better acoustics
Functional sound absorption that improves both working peace and structure
In offices, schools, and home environments where information needs to be visible and easily accessible, problems with echo and reverberation often arise. Hard wall surfaces combined with many simultaneous sound sources cause sound to reflect and build up in the room. Sound-absorbing notice boards are a solution that combines clear communication with effective sound absorption, contributing to a quieter and more functional sound environment.
What are sound-absorbing notice boards?
Sound-absorbing notice boards are made of porous materials that capture sound waves and reduce reflections in the room. When sound hits the surface, some of the sound energy is converted into heat energy, which shortens the reverberation time. This is clearly different from sound insulation, which aims to stop sound between rooms, and vibration damping, which reduces vibrations and structure-borne noise from structures and installations. Notice boards are therefore used to improve the acoustics where the sound already exists.
Common problems with echo and reverberation
Echo and long reverberation are common in meeting rooms, open-plan offices, corridors, and classrooms. Speech becomes more difficult to understand, background noise is perceived as more stressful, and concentration is impaired. In work environments, this can lead to increased stress, poorer communication, and lower efficiency. In home environments, well-being and focus are affected, especially in home offices and shared spaces.
How sound-absorbing solutions work in a room
Sound-absorbing products are placed on surfaces where sound reflections occur, usually on walls at ear level or near work and meeting areas. When sound waves hit the material, they are slowed down and absorbed, creating a more controlled sound environment.
Notice boards on walls
Sound-absorbing notice boards dampen reflections while also serving as information surfaces.
Combination with ceiling absorbers
In larger rooms, the combination of wall and ceiling absorption provides a more even sound image.
Complement to curtains and room dividers
Textile surfaces such as curtains and room dividers can enhance the effect by breaking sound waves from multiple directions.
Why choose sound-absorbing notice boards?
Sound-absorbing notice boards provide an immediate improvement in room acoustics without any intervention in the building. They are flexible, space-saving, and fulfill several functions at the same time. The result is noticeable in the form of better speech intelligibility, lower perceived noise levels, and increased peace and quiet. In many environments, they work best as part of a comprehensive solution that combines several types of sound absorption.
Well-considered advice for best results
For the best effect, notice boards should be placed where sound reflections are most noticeable, for example, near workplaces or meeting areas. In larger rooms, several boards can be used to create a sufficient absorbing surface. A common mistake is to underestimate how much sound absorption is required. By planning the placement strategically, you can create a long-term, functional, and pleasant sound environment.
Sound-absorbing notice boards are therefore an effective and practical choice for anyone who wants to reduce echo in a room while creating order, structure, and better acoustics.
