How do you reduce noise with sound-absorbing notice boards?

Sound-absorbing notice boards are an innovative solution that combines practical functionality with effective sound absorption. They are particularly useful in environments where both order and acoustic comfort are important, such as offices, schools, conference rooms, and other workplaces where noise levels are often high. By installing these bulletin boards, you can not only organize important documents and information, but also improve the room's sound environment by reducing disturbing reverberation and background noise.

What makes sound-absorbing bulletin boards unique is their material. Unlike traditional bulletin boards, which are usually made of cork or thin fiberboard, these are made of highly absorbent materials such as acoustic foam, compressed mineral wool, or polyester fiber. These materials capture and dampen sound waves instead of reflecting them, reducing the noise level in the room and improving speech intelligibility. By placing bulletin boards in strategic locations where sound is most reflected, such as on empty wall surfaces or near conversation zones, you can create a much more comfortable working or studying environment.

The benefits of sound-absorbing bulletin boards extend beyond their sound-dampening properties. They are an excellent option for those who want to improve the acoustics of a room without making permanent changes to the interior design. Since they are mounted on the wall in the same way as traditional bulletin boards, they are easy to install and can be replaced or moved as needed. In addition, they are available in a variety of colors, shapes, and sizes, making it possible to customize them to suit the aesthetic style of the room. In modern office environments, they can even serve as part of the interior design by adding both color and texture to the walls.

In open-plan offices, where noise levels are often high and concentration can be disrupted by conversations and background noise, sound-absorbing bulletin boards can contribute to a more focused and productive working environment. Placing them near workstations or in meeting rooms can effectively reduce echoes and create a more balanced soundscape. Similarly, in school environments, they can help improve acoustics in classrooms and group rooms, where students and teachers may otherwise have difficulty communicating clearly due to unwanted noise.

For those who work from home, a sound-absorbing bulletin board can be a simple but effective solution for improving the acoustics of the home office. By reducing sound reflections from walls, they can contribute to a calmer and more concentration-friendly working environment. In addition, they serve as a practical place to attach notes, schedules, or inspirational images, which can make the working day more organized.

In summary, sound-absorbing bulletin boards are a versatile and smart solution for combining functionality with improved acoustics. They help reduce reverberation, improve speech intelligibility, and create a more comfortable sound environment while providing a practical surface for organizing information. Whether in offices, schools, homes, or public spaces, these boards are an effective way to create a better and more productive sound environment without compromising on design or flexibility.

Sound-absorbing materials can help improve room acoustics without requiring extensive structural changes. This can be a cost-effective solution for improving the sound environment.

How does a sound-absorbing and sound-insulating notice board work?

A sound-dampening and sound-absorbing bulletin board is an innovative solution that combines practical functionality with acoustic improvement. These bulletin boards are used in environments where both information sharing and sound control are important, such as open-plan offices, schools, conference rooms, and other noisy spaces. By combining sound-absorbing materials with a surface that can be used to attach notes, pictures, or messages, these boards contribute to a more pleasant sound environment while fulfilling a practical function. They help reduce reverberation, reduce distracting background noise, and create a more focused atmosphere.

Materials and construction
Sound-absorbing noticeboards are constructed with special materials that effectively capture and dampen sound waves. The most common materials include acoustic foam, polyester fiber, wool, and fabric-covered panels. These materials have a porous structure that allows sound waves to penetrate the surface and be absorbed rather than reflected back into the room. The choice of material is crucial to how effective a notice board is in terms of sound absorption. Polyester-based bulletin boards are popular because they offer both high sound attenuation and durability. Acoustic foam is another effective option that has a high absorption capacity, especially for high-frequency sounds. In addition to the material, the sound absorption capacity is affected by the thickness and structure of the board. A thicker board generally provides better sound absorption, and some models feature a patterned or perforated design that further improves acoustics by breaking up sound waves and reducing reflections.

NRC value – an important factor when choosing a bulletin board
When choosing a sound-absorbing notice board, it is important to look at its NRC value (Noise Reduction Coefficient). The NRC value indicates how much of the incoming sound is absorbed by the material on a scale from 0 to 1. An NRC value of 0.6 means that the board absorbs 60% of the sound waves that hit it, while a board with an NRC value of 0.9 absorbs 90% of the sound. The higher the NRC value, the better the board is at reducing reverberation and improving the acoustics in the room. The choice of NRC value should be based on the specific needs of the room. In a noisy office environment or a school where many people are talking at the same time, a board with a high NRC value can make a big difference.

Placement and size for maximum effect
For a sound-absorbing bulletin board to be as effective as possible, its placement is crucial. Sound is reflected differently depending on the shape of the room, the materials, and the location of the sound sources. A general rule of thumb is to place bulletin boards on surfaces where sound is reflected the most, such as empty walls or surfaces opposite sound sources. If the goal is to reduce background noise in an open-plan office, it can be effective to mount notice boards on the walls around the workstations. The size of the board also affects how much sound it can absorb. In general, the larger the surface area covered, the more sound is absorbed. A smaller bulletin board can contribute to sound absorption, but for optimal results, at least 20-30% of the room's surfaces should be covered with sound-absorbing material. In larger rooms, several smaller bulletin boards can be placed strategically to spread sound absorption evenly across the entire surface. This can be particularly effective in rooms with hard surfaces such as concrete, glass, or plaster walls, where sound reflections are often a problem.

Combine with other acoustic solutions
To achieve the best possible sound reduction, sound-absorbing bulletin boards can be combined with other acoustic solutions. By using sound-absorbing panels on the ceiling, carpets on the floor, and soft furniture, the overall sound environment can be significantly improved. A comprehensive solution where different sound-absorbing elements work together provides more effective and balanced acoustics. This is particularly important in open-plan offices and schools, where multiple sound sources interact and a well-thought-out strategy is required to create a quieter working environment.

Limitations and realistic expectations
It is important to have realistic expectations of what a sound-absorbing notice board can achieve. These products are excellent for reducing sound reflections and reverberation, but they do not eliminate sound completely. If the room has poor sound insulation or if there are high noise levels from external sources, such as traffic noise or sound penetrating through thin walls, additional soundproofing measures may be necessary. This may include better window insulation, thicker doors, or the installation of specially designed sound barriers. A sound-absorbing bulletin board is therefore part of a comprehensive solution and should be used in conjunction with other acoustic measures to create an optimal sound environment.

Summary
Sound-absorbing notice boards are a smart and functional solution for reducing reverberation and improving acoustics in noisy environments. By combining sound-absorbing materials with a practical surface for attaching notes and messages, they serve a dual purpose in offices, schools, and conference rooms. Material selection, NRC value, placement, and size are crucial factors in determining how effective a bulletin board is at absorbing sound. By strategically placing them where sound is most reflected and combining them with other acoustic solutions, you can create a more comfortable and productive working environment. Although sound-absorbing noticeboards do not completely eliminate sound, they play an important role in reducing distracting background noise and creating better conditions for concentration and communication.

Did you know that..

Did you know that a sound-absorbing bulletin board not only dampens sound, but can also affect the acoustics of a room depending on what you put on it? Many people believe that the board itself does all the work, but if you cover the surface with dense materials such as laminated paper or plastic pockets, its sound-absorbing effect can be significantly reduced.

For the best sound dampening, the bulletin board should have a porous and open surface, such as felt or fabric, which allows sound to penetrate the material instead of being reflected back into the room. In addition, a thicker bulletin board with an acoustic core can absorb more frequencies and help reduce reverberation in offices, schools, and other sound-sensitive environments. By using it correctly, you can combine function and acoustic improvement in one!
