Previous Section
A balanced acoustical environment often pays an important part in improving productivity, comfort and peoples sense of well being. Through appropriate selection and placement of USG acoustical ceiling systems, it is possible to improve speech intelligibility, reduce unwanted noise or increase privacy within a space or between adjacent offices.
Sound attenuation
Sound attenuation refers to the attenuation of noise passing into a room from outside, such as room to room noise or noise from above ceiling services. The test data is represented in dB (CAC) according to the ASTM C1414 standard. CAC - defines the average 'room to room' sound attenuation of a ceiling system.

Sound absorption

Sound absorption describes the reduction of noise within a room. Acoustical ceiling tiles absorb sound energy and serve to control acoustic reverberation time. Different patterns provide different levels of sound absorption. Test data is represented in NRC according to the ASTM C423 standard. NRC defines the average sound absorption of a ceiling system.
