Acoustics
Whether your project is an airport terminal, auditorium, conference centre or lobby space, designers must consider the acoustic environment they create. Certain sounds need to be directionally steered and others reduced or eliminated. Designers are therefore recommended to consult with an acoustican in order to achieve the required results.
Gustafs Panel System® can help in this process to create an aesthetically satisfying and acoustically adjusted environment. Sound absorption, for example, is attained by using perforated or slotted panels in combination with mineral wool and air space.
Our various acoustic patterns are tested and documented to achieve known sound absorption coefficients for both walls and ceilings.
