Residential Acoustic Design Sydney
Acoustic design for homes, apartments and listening rooms, integrated with architecture, interiors and construction.
Acoustic design that looks and feels like home.
Acoustic comfort without compromise.
Home acoustics go beyond “soundproofing.” We design quiet, balanced rooms that fit your architecture — from bedrooms and studies to living spaces. Solutions are integrated into joinery, ceilings and textiles for a refined, residential feel.
Common projects
- Bedroom and apartment noise isolation (Rw and Rw+Ctr improvements)
- Open-plan and dining reverberation control (RT60 optimisation)
- Home office and studio acoustic treatments
- Home cinema layout and tuning
- Practical retrofit strategies for existing homes
Results you’ll feel
- Lower background noise for easier sleep and focus
- Clearer conversation in hard-surface kitchens and dining
- Controlled, immersive sound in listening rooms and theatres
Buildable acoustic design for architecture and interiors.
We collaborate with architects, designers and builders from concept to completion — aligning acoustic intent with materiality, lighting and services. The goal: details that preserve design language while delivering measurable performance.
Consulting services
- Early-stage acoustic strategy and documentation
- Wall, floor and ceiling systems with flanking control
- Mechanical and services noise management (AS/NZS 2107)
- DA acoustic reports and certification support (NCC F7, AAAC)
- On-site reviews and verification testing
For design teams
We provide mark-ups, detail packs and clear specifications so trades can execute efficiently. Early coordination reduces risk and protects the design language — especially in premium residential projects.
Experience that bridges architecture, interiors and acoustics.
Nicholas Marriott began his career on building sites before specialising in architectural acoustics and sustainable design. That dual perspective — understanding how materials go together and how sound moves through them — shapes every project.
With master’s degrees in Audio & Acoustics and Sustainable Design, Nicholas bridges science and aesthetics to achieve acoustic comfort without compromise. The approach is research-based yet practical: early design advice, clear documentation and buildable details that respect both architecture and budget.

Buildable acoustic design for architecture and interiors.
Residential projects often require acoustic strategies that respond to architecture, materials and construction, rather than relying solely on testing andreporting. we works as an acoustic consultant, acoustic designer and specialist in architectural acoustics, bringing together engineering insight and practical building knowledge to deliver comfortable andhigh-performing residential environments. Services within residential acoustic design include:
Architectural Acoustic Design
Development of acoustic strategies in collaboration with architects and designers, allowing sound control to be integrated naturally into residential architecture, materials and spatial planning rather than added as an after thought.
Acoustic Design for Renovations and Upgrades
Design guidance for improving acoustic comfort in existing homes and apartments, including strategies for managing sound transmission, reverberation and spatial acoustics as part of renovation or refurbishment projects.
Home Studio & Listening Room Design
Acoustic design for residential music spaces, home studios and critical listening environments, balancing acoustic performance with residential aesthetics and practical acoustic Integration with building construction
Development of acoustic solutions that are not only theoretically sound but also practical to build, informed by hands-on experience in construction methods, materials and building systems.
Collaboration with Architects, Builders & Project Teams
Working along side architects, designers and builders to ensure acoustic performance is considered early in the design process and carried through into the built outcome.

Residential acoustic design projects are undertaken across Sydney, including houses, apartments and specialist residential environments such as music rooms, home studios and listening spaces.
Selected residential work
Soundproofing reduces noise transmission between spaces. Acoustic treatment improves how sound behaves within a room. Most homes benefit from a balance of both.
Can acoustics be integrated during design?
Yes — early collaboration with your architect avoids costly retrofits and ensures solutions complement materials and lighting.
Do you work on apartments and heritage homes?
Absolutely. We specialise in discreet upgrades that preserve architectural character while improving privacy and comfort.
What standards guide your work?
We reference NCC F7, AS/NZS 2107 for internal sound levels, and AAAC guidelines for residential performance.
