LESS NOISE

Noise is an inevitable nuisance of the modern age. Surveys in New York and London have shown that noise problems rate more highly and effect more people than crime. Previous thoughts only concerned loud noise but now doctors and scientists realise that relatively low levels of noise over long periods can badly affect our health, raise blood pressure, disrupt cognitive development in children, disturb sleep and prompt psychiatric disorders. Getting away from noise is becoming more and more difficult.

Noise control in buildings is an effective method to reduce the problems by reducing the flow of the noise and acoustical insulation products are the answer. National and local authorities are constantly upgrading requirements to limit noise levels by improving the building code. Nowadays products can be installed, even retrospectively, to reduce the effects of external noises from lawn mowers, barking dogs, cars and trucks, chain saws, jack hammers, trains, planes, factory machinery, even noisy people in the street. Internal noises from televisions, sound systems, office noises, electric guitars, other musical instruments, computer games, clothes dryers, washing machines, noisy pipes, air conditioning and people from above walking on hard floors can also be controlle

Products can be used in systems or sometimes individually and include:
             *Soft fibre, acoustic, batt insulation to absorb sound.
             * Dense, loaded vinyl barriers to block noise through ceilings and walls.
             * Pipe lagging to deaden water and waste noise.
             *Baffle Block as an inter-office sound control system.
             *Impact resilient mounts to de-couple hard surfaces.
             *Acoustic, composite fabrics to reduce reverberation (echo) noise.
             *Windows, doors and seals.
*Not only does the Building Code of Australia rely on these products to support their new regulations but they can also be used in vehicles, boats and heavy equipment.

PRODUCTS & APPLICATIONS

Dense polyester or sheep’s wool batts in ceilings, walls under floors and around all types of ducts and machinery will absorb sound, either individually or combined with other products. It also becomes a de-coupling (a compliant separator that reduces sound waves) agent when used in conjunction with other noise barrier products.
Loaded vinyl barriers are dense flexible curtains that (due to their high mass to stiffness ratio) exhibit high noise reflection capabilities.  They are constructed from polyvinyl-chloride (PVC) and encapsulate barium for high density in a sheet form supported by a woven fabric. They are used for:

    *Increasing transmission loss of walls, floors and ceilings (aircraft noise).
    *Baffling for reduction of cross talk (offices with suspended ceilings).
    *Curtaining of noisy factories and in and outdoor machinery (motors in factories, trucks and boats).
    *Optional decorative and protective surfaces are available.

Pipe wrap is a composite of loaded vinyl and acoustic foam or polyester fibre insulation.
Used to reduce the noise breakout from pipes for water, waste or air as in drainage pipes and air-conditioning ducts. The foiled vinyl exterior is fire resistant and is fixed by aluminium tape.

Baffle Block is compressed layers of Quietstuf polyester batts placed above acoustic partitions in offices between the suspended ceiling and the concrete slab above. Baffle Block eliminates cross talk and can also mould around service ducting reducing more noise.
Impact mounts, made of a variety of products, are installed between ‘hard’ floors and structural work to reduce the noise caused by impact vibrating through a structure. Noises as simple as shoes impacting on tiles or as complex as machinery can penetrate through a building.
Reverberation fabrics made of composite materials in a large range of colours can be installed on walls, ceilings and furniture to reduce the echo that bounce off surfaces. They also become a decorative feature.
