We develop the products
that improve
the room acoustics
Deeper learning of the acoustics issues and developing the products that are passive in terms of the acoustics enables to design the spaces that improve the room acoustics not only in the offices, but also in the public and HoReCa spaces.

Sound propagation
Sound
Sound – is an auditory impression,
caused, by the acoustic wave propagated
in the solid body, fluid or gas.
Interior acoustics
Interior acoustics specifies how sound
behaves in the room.
The movement, attenuation, absorption,
sound reflection are the most important acoustic aspects.
Basic acoustic phenomena
Reflection
Absorption
Dispersion
Attenuation
Acoustic products of Bejot
have the sound absorption certificates
specified on the basis of ISO 354 standard.

Enjoy the silence
Ask about a purpose of the office and a nature of the work of the persons who stay in it.
For greater efficiency, use a ceiling and two adjacent, perpendicular walls (one from a pair of the horizontal ones).
Remember about insulating from the noise sources – the higher the screen, the better. A tightness of the partition is of importance, too.
A closer location of the acoustic products in respect of a sound source will enable to absorb a greater amount of the sound.
Fill as much space as possible with the soft elements, e.g. upholstered furniture, floor covering.
A proper work organisation, e.g. a separation of the silence zones, communication and a team work will help improve the acoustic conditions.
