Soundproofing or noise control especially in the inner suburbs is effective to provide an enjoyable environment.

Windows: Double glazing of the windows facing the noise is the best solution here. Aluminium sliding windows have the best performance and are the easiest to live with.

Magnetic acrylic window systems are not so but are a great option where aluminium sliding cannot be installed.

The main focus of residential soundproofing in existing structures is the windows. The primary sound proofing limit of curtains is the lack of a seal at the edge of the curtain. Double-pane windows achieve somewhat greater sound damping than single pane windows. The increase in soundproofing with higher energy efficiency windows is primarily due to thebetter seals on double-pane than single pane windows.

Walls: If the walls constitute part of the problem a secondary sub wall and or ceiling as described below may be necessary.

There are varying degrees and expectations on soundproofing a wall. Keep in mind that if you can reduce the amount of noise from passing through that wall by 10 Decibels that you have cut the amount of noise that can be heard by 50%.

Airborne noise intrusion can be treated via the installation of a sub ceiling or secondary wall mounted adjacent to the existing. It can be drywall construction and should utilise isolation mounts and acoustic insulation. Be aware that if the spaces share a common ceiling cavity that may also be a noise path and may require treatment.

Soundproofing your space may need more than one product to resolve the issue completely, Noise pollution is a big issue in our increasing urban space.

Doors: Where the doors are suspect, replacement with solid core doors, complete with acoustic seals, to the relevant rooms is recommended.

Underfloor: If the property is on stumps, a treatment to the floor and to the area below the floor around the perimeter should be considered.

Roof: Installation of acoustic insulation into the roof cavity may also be required.

If your home is older, your attic may lack insulation. Not only will adding insulation help reduce your energy bills; it can also help in your endeavour to soundproof your home. If you have an asphalt roof, adding extra layers of roofing material is an additional way to help dampen or eliminate noise, especially where aircraft is ever-present.
