Acoustics in a building
Improve the acoustics in your building? In fact, the concept of ‘acoustics’ is the influence of a building on the transmission of sound. A building and all its properties reflect and attenuate sound waves.
Unfortunately, it is often the case that sound waves are not attenuated enough. Reverberation therefore plays a role in many spaces. Poor acoustics affect your peace of mind, productivity and audibility. We measure the reverberation of a building and we know how to make it pleasant again in the right way.
Every year we carry out more than 300 projects in offices, catering, care facilities, education and industry. We also supply various solutions for improving the acoustic situation at home.
Hard materials such as concrete, tiles and wood are often used in new buildings and renovations. As a result, sound is highly reflective. This makes a room sound hollow.You can also contact our experts for these situations.

Acoustics in buildings
EASY Noise Control offers an acoustic solution for every application. The most common situations:
In the past, a suspended ceiling was installed in almost every business building. Suspended ceilings make an important contribution to good room acoustics.
Nowadays, such ceilings are used less and less frequently. This is mainly for aesthetic reasons, but sometimes also for technical reasons. For example, because of concrete core activation. Time for new sound attenuation solutions!
In order to improve room acoustics, sound absorption must therefore be applied by other methods. You therefore see more and more solutions on the market that reduce reverberation in an aesthetic way.
These solutions are often mounted on the ceiling and wall. This is where there is most room for such solutions. Moreover, these places are often the closest to the source.
In addition, these are the reflective surfaces in the room that in most cases cause the acoustic problem.
Acoustic ceiling panels, acoustic baffles and acoustic wall panels are often used as absorption solutions.
How does poor acoustics occur?
Sound waves are produced and spread in all directions. A sound wave comes into contact with a surface. Part of the sound is absorbed and part is reflected.
The louder the surface, the greater the percentage of sound that is reflected. This causes reverberation in the room.
The amount of reverberation is expressed in reverberation time. This is the time in seconds it takes for a sound to decrease 60 dB in strength. In general, the longer the reverberation time, the worse the situation.
What are the effects of this?
A long reverberation time is at the expense of speech intelligibility. In addition, the sound level is increased and it takes more energy to concentrate. Moreover, it has a negative influence on the wellbeing and rest of those present. This can lead to headaches, fatigue and long-term stress.
A low reverberation time leads to a better sound quality, which makes the room feel quieter. In addition, speech intelligibility in the room will be improved and the sound level will decrease. This is because people will drown each other out less in order to make themselves understood.
In the end, this ensures more peace and comfort, higher productivity and less stress. In this way, good acoustics play a role in a healthy, productive and comfortable living and working environment.
How do you reduce reverberation and get a better acoustic situation?
The reverberation time in a room is improved by adding sufficient absorption to a room. Preferably as close as possible to the sound source(s). For good acoustics, we recommend a combination of acoustic solutions on the ceiling and walls.
For an acceptable situation, you should use 30 to 40% of the floor surface material. This means that in a room of 100m2 you will install approximately 40m2 of high-quality acoustic facilities. This rule applies to a height of up to 3 metres. For a perfect situation this is about 50-60%.
These facilities absorb sound waves so that they are not or less reflected. For a space of 100m2, this means that approximately 30m2 – 40m2 of high-quality facilities are required.
