Acoustic insulation is the "term" used to describe the technique by which sound-blocking, sound-absorption or sound-isolation materials are used in the construction of building elements to reduce the level of noise by suppressing or stopping sound waves. Sound is a form of energy. When sound becomes loud, persistent and high pitch, it will become disturbing. Any unwanted sound is noise and with today’s awareness for occupational health and environmental issues all unwanted noise is considered ‘noise pollution’.
In Australia, the national exposure standard for noise in the working environment is an average daily exposure level (LAeq,8h) of 85 dB(A), or a peak sound pressure level (LC,peak) of 140 dB(C).
Through collaborative research projects with VIPAC and CSIRO, LAF have engineered acoustic insulation systems to either prevent the transfer of sound (through vertical or horizontal membranes) from one compartment to another or, abate sound waves within a compartment, to improve speech intelligibility.
