Outstanding acoustics

Lumir is suitable for any space that needs better acoustics: e.g. schools, kindergartens, agencies, hospitals, offices, hotels, restaurants, churches and cultural institutions can all benefit from reduced reverberation.

Reverberation

Reverberation is caused when sound reflects from surfaces.

Reverberation is affected by the shape and materials of a room or space.
Materials that absorb sound can shorten the reverberation time.
Absorption coefficient α is used to describe how materials affect the reverberation time.
If a surface absorbs sounds well the value of α is 1, and if the absorption is poor then the value of α is 0.
Absorption value varies with frequency.

Lumir improves the usability of a space

Acoustics have an impact on the usability and comfort of spaces, on how we work, concentrate and understand. Good acoustics may go completely unnoticed – poor acoustics such as too strong reverberation can make a space useless.

If a surface has poor sound absorption, it reflects the sound back into the space making the reverberation time long. This in turn makes it very difficult to understand speech and has a negative effect on working, learning and comfort. That’s why poor acoustics is a waste of time and money.

Lumir acoustics are created using a Lumir Board bottom plate that absorbs low frequencies and a Lumir acoustic coating that absorbs high frequencies. The surface is hard and durable unlike a wool panel surface.

Natural acoustics based on science:

Lumir’s products are developed by highly educated scientists from the fields of materials science and acoustics
Lumir aims to produce the highest quality acoustic solutions in the world that are also visually appealing
