Acoustics

We live in a world of noise pollution.

The sounds of the natural world have been replaced by a acoustic rubbish dump. We are constantly bombarded by unwanted sounds from busy streets and neighbours, as well as the hum of electronic devices and conversations among those around us.

What is sound?

Sound is an audio effect caused by an acoustic wave, which can be described as a wave of changing pressure: loud sounds create large waves with high energy, quiet sounds – smaller waves. Sound is measured as the level of acoustic pressure, expressed in decibels (dB).

What is noise?

We call noise any unwanted sound which can be simply irritating or actually detrimental to our health. A harmless level of noise is only 50 dB, while an increase in noise to 70 dB leads to changes in the body, and above 130 dB causes physical pain.

Know what we mean about noise?

In open space offices, 50% of employees complain of noise. 64% of employees think that eliminating noise would increase their effectiveness at work.

Devices • telephones • computers • printers • coffee machines

People • conversations • footsteps • chairs scraping • door slamming

By using the appropriate solutions and materials, acoustic comfort can be ensured in the workplace.

Acoustic comfort is the result of an ideal combination of sound absorption and penetration.

What this means

akustyka

Echo

(the reflection of sound)

Sound waves spread out from the sound source in the direction of the ceiling, walls, floor, people and objects. Part of this energy is absorbed or passes through the barrier, while the remainder is reflected, causing echoes. The greater the number of times the sound wave is reflected, the longer the echo lasts and the greater the acoustic discomfort.

Absorption

(pochłanianie)

The absorption of sound is the transformation of sound energy into mechanical vibrations and heat. Materials with appropriate absorption parameters improve the acoustics of a room by eliminating the reflection of sound and thus reducing echoes.

Penetration

(acoustic insulation)

A pleasant acoustic environment is not only the result of echo and absorption parameters, but also of penetration. These parameters determine insulation from sounds passing through barriers such as a wall, ceiling or partition wall used as a sound screen.

The CELL and ECLIPSE panel collections were designed to ensure acoustic comfort in office spaces, commercial premises, public buildings and homes.

Sound insulation

The excellent insulating properties of the CELL and ECLIPSE acoustic panels has been confirmed in tests conducted according to the PN ISO 10053:2001 standard by the Technical Acoustics Laboratory of the AGH Mechanics and Vibroacoustics Academy in Cracow.

Sound absorption

CELL and ECLIPSE acoustic panels also improve the acoustics of interiors thanks to their absorption properties (class D) according to the PN-EN ISO 354:2005 standard. The sound parameters of the panels are achieved thanks to the material used as well as their shape.
