Why Acoustic Treatment
Noise. An irritant, a pollutant, a health hazard, yet accepted by many as ‘normal .
A good acoustic office environment can:
-
Increase motivation by 60%
-
Increase problem solving by 20%
-
Increase complex task efficiency by 50%
-
Lower adrenaline levels by 30%
Reverberate noise Рan infinite number of sound reflections that will keep the ‚Äö√Ñ√≤source sound audible for a short period of time.
Hard surfaces will reflect the sound more and bounce the noise wave back to meet its source, whereby it then joins the second wave of noise transmission
and subsequently a third etc.

The performance of sound absorptive insulation is typically described by the Noise Reduction Co-ecient of the product. This NRC is a simplified single number that is the arithmetic average of noise attenuation over four frequencies: 250Hz, 500Hz, 1,000Hz, and 2000Hz.
In sound absorption applications, the NRC is often used as a performance measure, the higher the NRC, the greater the sound absorption at those frequencies.
However, NRC does not rate sound absorption at frequencies less than 250Hz. Absorption at low frequencies is often the most critical in building acoustics since it is typically the base sound that causes annoyance.

Why SANA 3D Tiles?
SANA 3D tiles are amongst the most ecient methods of combating reverberate noise, either planned from the outset as a design feature or retrofit as a cure for any previously unforeseen ‚Äö√Ñ√≤noise annoyance factor Рthe latter being experienced in most commercial interiors.
The control of reverberate noise in spaces where people work, relax, socialise and learn is of critical importance. ‘Reverberant spaces are not natural environments for humans. Spending time in
such spaces can have negative impact on productivity, learning, recuperation, enjoyment and well-being.
