Noise is an unwanted sound. Its intensity (loudness) is measured in decibels (dB). The strength or intensity of sound is usually measured in A – weighted decibels (dB (A)). STC ratings give a single value, the higher the rating the better the sound insulation. For more information, see our guide to the meaning of sound levels.
CDL's Acoustic Doors up to STC70 are independently tested to BS EN ISO 717-1 and manufactured to ISO 9001: 2008 quality control system. CDL Custom Acoustic doors are designed to provide sound insulation in a wide variety of applications including performing arts centers, theaters, concert halls, T.V. Studios, pumping/power stations, research & test facilities and a host of other uses where noise transmission is a key concern.
For an STC rated door set, the door panel, surround frame and seal system should be tested as a combination: all CDL Acoustic Doors are tested in this manner. The sound performance of the building wall, ceiling and floor should also be assessed when selecting an acoustic door set as good performance can be undermined by flanking sound leakage on the construction. IT IS RECOMMENDED THAT EXPERT ADVICE FROM AN ACOUSTICAL CONSULTANT IS SOUGHT TO ENSURE THAT THE DESIRED OUTCOMES ARE ACHIEVED.
