learn more about acoustics

Whether it is an office, restaurant or public space, everyone has experienced it: a beautifully decorated space where it is impossible to have a conversation. This is especially known for ‘open plan offices’ in which hard and smooth materials have been incorporated. Colleagues on the phone, spontaneous consultation between office workers, equipment that is switched on: employees have to endure a lot of noise in the workplace.

In buildings, noise, or rather poor acoustics, can be a source of annoyance. Good acoustics are therefore of great importance for the productivity and well-being of people.

Good acoustics depend on the function of the room and factors such as intelligibility, privacy, and concentration. A good sound climate improves the space and fulfills an essential role in the experience of work, mutual contact and personal well-being. That is why we develop acoustic lighting elements.

Our acoustic lamps absorb sound and reduce reverberation time, unobtrusively in the room or as a special, striking eye-catcher. In this way they fit into any interior while preserving the open character of the space.

How to control sound

You can’t always control sound at its source. For example in a conversation, a buzzing computer or a door slamming. Therefore it is important to control sound in the complete environment. In a free space (mainly outdoors), sound will always travel in a straight line. But as soon as there are obstacles in a space, sound will bend or reflect. This is something we can actually use to create a more optimal acoustic environment. The two most important aspects of sound we use to do this are absorption and diffusion.

Absorption is the measure of the amount of energy removed from the sound wave as the wave passes through a given thickness of material.

Diffusion is the method of spreading out sound energy. The shape of an object can deform the structure of sound when they come into contact.


Absorption is the most common value to tackle for optimal acoustics. How much sound you ‘catch’ is expressed into acoustic value (aw). Soft materials (PET Felt) catch a lot of sound and have a high aw. Hard materials reflect sound and have a low aw


After a sound has been made, its waves continue to travel. When this sound hits a surface, such as a ceiling or wall, it will keep on traveling in a space. The sonic effect that this produces is what we call reverberation. Reverberation is often experienced as unpleasant. This is why we tackle this effect with our products; in order to make the overall experience in a space better.
