Frequently Asked Questions
Who are the best soundproofing companies in Sydney?
The best soundproofing companies in Sydney combine technical expertise with proper installation — not just product sales. Look for businesses that carry out acoustic site assessments before quoting, can provide STC and Rw performance data for the systems they install, and offer written warranties on both materials and workmanship.
Acoustica Projects has been solving noise problems across Sydney since 1994. With in-house acoustic assessors, a design and installation team, and more than three decades of completed projects across residential, commercial, and specialist spaces, they offer end-to-end service from initial diagnosis through to finished installation.
It’s always worth booking a proper site assessment rather than relying on a phone or photo quote — the difference in the quality of the recommendation is significant.
Contact Acoustica Projects to book a free consultation and site assessment.
What is the average cost of residential soundproofing in Sydney?
Noise control work cost in Sydney, when professionally assessed and installed, is influenced by a number of local factors. Depending on where you live, the older weatherboard homes require more extensive gap sealing than brick construction; coastal humidity and salt air require moisture-resistant materials that may carry a small premium; and port, industrial, or low-frequency airport noise may require greater acoustic mass than standard road traffic noise. The final figure depends on the noise type, your home’s construction, the level of reduction required, and whether windows are involved.
DIY products are cheaper upfront but frequently miss the weak points that matter most: door gaps, electrical penetrations, and structural flanking paths that allow noise to bypass the treatment entirely. A professional assessment identifies all of these before any work begins.
Get in touch with Acoustica Projects for a no-obligation site assessment and written quote.
What are the best soundproofing options for apartments in Sydney?
Soundproofing a Sydney apartment comes with specific constraints — most strata schemes restrict permanent structural changes, and rental properties limit modifications further.
For owners with strata approval, more substantial improvements are possible: resilient channel wall systems, acoustic plasterboard, and Sonicka K Range vinyl can deliver meaningful reductions in noise through shared walls, floors, and ceilings. The most important first step — regardless of tenure — is identifying exactly where the noise is entering, which is often not where it appears to be coming from.
Acoustica Projects works with Sydney apartment owners, strata managers, and renters regularly and can advise on both permanent and non-permanent solutions for any situation.
Contact the team to discuss what’s possible in your apartment — a consultation is a good starting point.
What is the best soundproofing for homes near busy roads in Sydney?
For homes near busy roads — Parramatta Road, the Pacific Highway, Victoria Road, or local arterials — both walls and windows are the weak point. In severely affected homes, additional wall mass and decoupling may also be warranted. Hard floor surfaces that reflect and amplify incoming noise are also worth addressing. Focus on sealing air gaps around frames and doors — even small openings significantly reduce the effectiveness of upgraded glazing.
A single-glazed timber window lets in dramatically more noise than a properly insulated one, and replacing or upgrading windows typically delivers the most noticeable improvement for the investment.
Acoustica Projects assesses road noise problems across Sydney every week. Get in touch to arrange a free consultation.
What are the best soundproof windows for homes near Sydney Airports?
Aircraft noise is low-frequency and requires substantial acoustic mass to block effectively. For homes in the affected corridors — Mascot, Marrickville, Tempe, Sydenham, Botany, Rockdale, Wolli Creek, Tempe, Alexandria, Rosebery, Kyeemagh, and Brighton-Le-Sands – for Sydney (Kingsford Smith) Airport and Badgerys Creek, Luddenham (adjacent to runways), Bringelly, Austral, Bradfield City Centre (new city), Orchard Hills, Leppington, Oran Park, and Rossmore – for the new Western Sydney International (Nancy-Bird Walton) Airport,— acoustic glazing with a minimum Rw rating of 35–40 dB is generally recommended. Standard double glazing often falls short at these frequencies.
Secondary glazing (an inner pane installed behind your existing window) is frequently the most cost-effective solution for established homes, as it avoids full window replacement while delivering comparable acoustic performance. Acoustic laminated glass — which uses a sound-dampening interlayer — also outperforms standard double glazing at the same thickness and is worth specifying when replacement is the right path.
Acoustica Projects supplies and installs acoustic windows throughout the Sydney Airport flight paths.
Not sure what Rw rating you need? Contact the team for an assessment — we’ll recommend the right solution for your property and budget.
How do I soundproof a party wall in a Sydney terrace house?
Soundproofing a party wall in a Sydney terrace house requires adding both mass and decoupling to the existing structure — the two core principles of acoustic isolation. Simply adding a layer of plasterboard to a brick party wall rarely delivers satisfying results, because sound travels structurally through the masonry regardless of what’s on the surface. The most effective approach is a decoupled internal wall system: a new wall frame physically isolated from the existing structure, filled with acoustic batts, and lined with acoustic plasterboard or mass-loaded vinyl.
This does reduce the room’s footprint slightly — typically 70–100mm — but the acoustic improvement is substantial, reducing noise transmission by 15–25 dB in most cases. It’s also important to treat the ceiling junction and floor perimeter, as flanking noise through these paths can undermine even excellent wall treatment.
Party wall work in terraces is complex enough to warrant professional installation. Acoustica Projects has completed this type of project across Newtown, Glebe, Surry Hills, Paddington, Rozelle and the broader Inner West.
Contact the team to discuss what’s possible in your terrace — and to get a clear scope and quote before any work begins.
Can soundproofing help with strata noise disputes?
Yes — soundproofing can often resolve noise disputes between apartments that strata mediation alone has been unable to fix. A professional acoustic assessment can also document the noise levels and transmission path with objective measurements, which is valuable evidence if a dispute escalates to the NSW Civil and Administrative Tribunal (NCAT).
Common effective solutions include acoustic underlay and flooring upgrades for footstep and impact noise from above, wall treatment on shared party walls, and ceiling isolation systems for airborne sound from adjacent apartments. Many of these solutions can be installed from within your own apartment without requiring access to the neighbouring unit.
Acoustica Projects works with Sydney strata owners, strata managers, and building managers on noise issues and can provide a written assessment report if one is required.
If you’re dealing with a strata noise problem, contact the team — an objective professional assessment is often the most useful first step.
How do I reduce train noise in a house near railway lines?
Train noise combines two types: airborne noise (the sound of the train) and low-frequency vibration transmitted through the ground and building structure. Windows are the primary entry point for airborne noise, so acoustic glazing is usually the first and most impactful investment. Homes within 200 metres of a railway line typically need acoustic glass with an Rw rating of at least 35 dB — standard double glazing may not be sufficient.
After windows, sealing air gaps around frames, vents, and penetrations is critical — small openings significantly reduce the performance of even good acoustic glazing. In homes very close to railway lines, additional wall treatment and floor isolation can help with low-frequency vibration, which is harder to address than airborne noise.
Newtown, St Peters, Redfern, Strathfield, Parramatta, Sydenham, and many other suburbs along Sydney’s rail corridors are commonly affected.
Contact Acoustica Projects to arrange a site assessment — we’ll identify the main noise paths and recommend the most cost-effective treatment for your home.
Do I need council approval for soundproofing work in Sydney?
Most internal soundproofing work in Sydney does not require council approval. Adding acoustic insulation to walls, installing acoustic underlay under flooring, fitting acoustic panels, or sealing gaps around doors and windows are all considered maintenance or minor works.
However, there are exceptions worth knowing. Replacing windows or doors — including installing secondary glazing as a structural addition — may require approval in heritage overlay areas or under certain strata by-laws. Structural changes, such as adding a new internal wall, may require a Complying Development Certificate (CDC) or Development Application (DA) depending on the scope. In strata buildings, written approval from the owners corporation is generally required before any permanent changes to common walls, floors, or ceilings.
Acoustica Projects can advise on what approvals, if any, are needed for your specific property before any work begins — it’s always better to check first. Contact the team for guidance.
What questions should I ask a soundproofing contractor in Sydney?
Choosing the right soundproofing contractor in Sydney is worth taking seriously — poorly installed soundproofing can be expensive to redo. Before committing, ask any contractor these questions:
• Do you carry out an acoustic site assessment before quoting, or do you quote from photos and a phone call?
• Can you provide acoustic performance data — STC or Rw ratings — for the systems you install?
• Are you installing the work yourselves, or subcontracting?
• Do you offer a warranty on both materials and workmanship, and for how long?
• Can you provide references or case studies from similar projects?
• Will you provide a written scope of works before starting — not just a verbal quote?
• Do you have specific experience with this type of noise problem — road traffic, aircraft, strata, terrace party walls?
Acoustica Projects is happy to answer all of the above — and will always conduct a proper site assessment before making any recommendation. Contact the team to book yours.
