Who Are the Best Acoustic Consultants in Perth?

There is no single “best” acoustic consultant for every residential or building project in Perth. A useful shortlist includes Nicholas Marriott, Herring Storer Acoustics, Lloyd George Acoustics, Acoustic Engineering Solutions and Marshall Day Acoustics—but the right choice depends on the building type, approval pathway, required evidence and delivery model.

This comparison is based on publicly stated capabilities checked on 12 September 2026. It is not a league table or an endorsement of every service offered by each practice. Confirm the proposed personnel, scope, qualifications, availability and fees directly before appointment.

Which Perth Acoustic Consultants Should You Compare?

These providers represent different service models, from a small design-and-build practice working nationally to established Western Australian and international consultancies. “Residential and building projects” can mean one home, a neighbour-noise investigation, a transport-noise assessment or a major apartment development, so compare the fit carefully.

When Is Nicholas Marriott a Good Fit?

Nicholas Marriott may suit projects where acoustic design must connect closely with buildability, interior constraints and construction sequencing. The service is relevant to bespoke homes, renovations, recording studios, listening rooms and media rooms where small details at junctions, penetrations, doors and ventilation paths can determine the outcome.

The practice combines acoustic design, research and practical construction knowledge. Design and documentation can be provided nationally, while Perth site attendance, testing and construction involvement should be confirmed for the project.

This model is not automatically right for every brief. A large statutory development, extensive environmental monitoring programme or project requiring a particular engineering registration may be better matched to a larger consultancy or another suitably credentialled specialist.

When Is Herring Storer Acoustics a Good Fit?

Herring Storer Acoustics may suit Perth projects involving building acoustics, mechanical-services noise, environmental assessment, transport noise or vibration. Its website describes a Western Australian practice established through a Perth consultancy history dating to the late 1970s and early 1980s.

For apartment and mixed-use projects, confirm the proposed team, design stages, documentation, construction inspections and verification testing. For a private home, check that the scope and fee structure match the scale of the problem.

When Is Lloyd George Acoustics a Good Fit?

Lloyd George Acoustics may be a strong comparison where a home or development is affected by road or rail noise. Its website describes measurement, modelling and assessment against criteria including Western Australia’s State Planning Policy 5.4, with mitigation advice where required.

Developers, planners and homeowners should confirm whether SPP 5.4 applies to the specific site, what future traffic assumptions will be used and whether the engagement includes façade, ventilation and construction documentation rather than only a planning report.

When Is Acoustic Engineering Solutions a Good Fit?

Acoustic Engineering Solutions is an independent Perth-based consultancy publicly offering environmental noise, transportation noise, building acoustics, measurements, vibration analysis and noise-control design.

It may be worth comparing for domestic plant noise, local development assessments, field measurements and smaller building-acoustic assignments. Ask for relevant residential examples and make sure the proposal defines the test method, assessment criteria, deliverables and review process.

When Is Marshall Day Acoustics a Good Fit?

Marshall Day Acoustics may suit complex architectural-acoustic, environmental-noise and vibration projects requiring the resources of a large international practice. The firm describes work ranging from small developments to major infrastructure and facilities.

For a major apartment, mixed-use, cultural or specialist interior project, confirm the current Perth team and comparable experience. For a private home, ask whether the proposed personnel, stages and fee are proportionate to the brief.

Which Western Australian Requirements May Affect the Brief?

Western Australian residential and building projects may be assessed under several different instruments. The correct pathway depends on the development, location, noise source and approval conditions.

When Does State Planning Policy 5.4 Matter?

SPP 5.4 addresses road and rail noise for noise-sensitive land uses in relevant transport corridors. Where it applies, the work may involve noise exposure assessment, future traffic assumptions, façade or barrier mitigation, ventilation considerations and planning documentation.

How Do the Environmental Protection (Noise) Regulations Apply?

Environmental noise from mechanical plant, commercial activity and other sources may be assessed against Western Australia’s Environmental Protection (Noise) Regulations 1997. The assigned levels depend on factors including the receiving premises, time of day and influencing factors around the site.

The consultant should state which regulatory provisions and adjustments apply, how measurements or predictions will be undertaken, and what assumptions affect the conclusion.

What About the National Construction Code?

Multi-residential and other classified buildings may need to meet National Construction Code sound-insulation provisions. The relevant requirements depend on the building classification, separating construction, services and project pathway. Confirm whether the consultant is providing design advice, a compliance report, an alternative solution, site inspections or verification testing.

How Do the Service Models Differ?

Practice size does not establish quality. The relevant difference is how the proposed delivery model, assigned personnel and resources fit the project.

When Does a Small Integrated Practice Help?

It can help where the main risk lies in turning acoustic intent into buildable details and coordinating those details with a bespoke home, renovation or studio. Clients may deal directly with the same person through diagnosis, design and construction queries.

When Does a Larger Consultancy Help?

It can help when a project needs a larger team, extensive modelling, formal engineering inputs, monitoring, specialist disciplines or resources across a long development programme. This is often relevant to apartment towers, mixed-use developments, infrastructure interfaces and complex approvals.

What Should You Ask Before Choosing?

Ask every shortlisted consultant the same questions so proposals can be compared on a like-for-like basis.

• Have you completed a project with the same building type, noise source and approval pathway?
• Who will complete the work, and what relevant qualifications, memberships or registrations do they hold?
• What investigation, testing, modelling and site attendance are included?
• Which WA planning policies, regulations, NCC provisions or project criteria will be applied?
• What drawings, specifications, reports and construction details will be delivered?
• Are authority responses, design revisions and construction-stage questions included?
• How will the completed work be inspected or tested?
• What limitations, exclusions and additional fees apply?

What Information Should You Prepare Before Requesting Advice?

A clear brief helps a consultant define the appropriate investigation, deliverables and limitations before appointment. Prepare:

• The project address, building type and relevant room or receiver locations.
• Plans, photographs and available construction details.
• The noise source, when it occurs and the spaces affected.
• The project stage, approval pathway and any consent, strata or body-corporate documents.
• The required outcome, such as diagnosis, design, testing, reporting or construction support.
• Known access constraints, work already attempted, budget range and programme.

What Are the Limits of This Comparison?

Public websites cannot establish the quality of every consultant, the suitability of an individual staff member or the outcome of a future project. Team composition, registrations, services, availability and fees can change.

This shortlist is therefore a starting point. Request a written scope, verify current credentials and compare relevant project evidence before making an appointment.

Choose the Consultant Who Fits the Actual Perth Project

A bespoke home requiring close design and construction coordination is different from an apartment development requiring formal documentation, or a transport-corridor site requiring an SPP 5.4 assessment.
