Commercial Soundproofing Built Into the Project From the Start
PRE-CONSTRUCTION ACOUSTIC ISOLATIONAcoustic isolation for commercial interiors, new construction and major renovations across Toronto and the Greater Toronto & Hamilton Area. Inaudible works with builders, general contractors and design teams to identify sound paths early and integrate the required wall, ceiling, insulation and isolation details before the assemblies are closed.
Walls • Ceilings • Plenums • Mechanical Noise • Speech Privacy • Isolation Assemblies
Acoustic Problems Are Easier to Prevent Than Retrofit
A wall can be built exactly as specified and still fall short if sound is able to travel around it.
Ceiling plenums, ductwork, electrical penetrations, junctions and rigid structural connections can create alternate transmission paths that only become obvious after the space is occupied.
Pre-construction acoustic planning gives the project team an opportunity to address those conditions while the framing, cavities and overhead systems are still accessible.
COMMERCIAL Sound Isolation solutions
Acoustic Isolation Across the Complete Assembly
Sound control rarely comes from one product. We look at how the wall, ceiling, cavity, structure and building services work together before selecting the treatment.
Wall & Ceiling Isolation
Decoupling methods, additional mass and assembly detailing for partitions and ceilings where greater sound separation is required.
Perimeter & Penetration Sealing
Acoustical sealants, putty pads and related detailing around assembly edges, outlets and penetrations where gaps can compromise sound isolation.
Acoustic Insulation
Dense-fill cellulose or mineral wool incorporated into wall and ceiling cavities according to the construction requirements.
Plenum & Above-Ceiling Treatments
Acoustic treatments for sound paths above suspended ceilings, including conditions where partitions do not provide sufficient separation through the shared plenum.
Acoustic Drywall Systems
Specialty gypsum and multi-layer drywall configurations where additional mass or damping forms part of the isolation strategy.
Mechanical & Duct Noise Control
Practical treatments for ductborne or equipment-related noise where mechanical systems create a path between spaces.
BEFORE THE WALLS CLOSE
Four Places Acoustic Performance Commonly Gets Lost
01 · Junctions
Sound can bypass the main partition through the floor, ceiling or adjoining walls where assemblies connect.
02 · Penetrations
Electrical boxes, services and other openings can introduce weak points into an otherwise well-built assembly.
03 · Ceiling Plenums
Partitions that terminate at a suspended ceiling can leave a shared path above the rooms for airborne sound.
04 · Mechanical Systems
Ductwork and equipment can carry sound between spaces even when the wall construction itself is strong.
Sound Isolation Is a System, Not a Product
Effective sound isolation typically combines several strategies. Which ones are needed depends on the noise source, construction and performance objective.
Mass
Additional layers help resist airborne sound transmission through the separating surface.
Decoupling
Isolation clips, channels and separated framing conditions can reduce direct vibration transfer through rigid connections.
Cavity Treatment
Cellulose or mineral wool helps control acoustic energy within the wall or ceiling cavity.
Airtight Detailing
Perimeters, joints and penetrations need to remain properly sealed so small openings do not become unintended sound paths.
The strongest assembly is only as effective as the details connecting it to the rest of the building.
PLENUM / ABOVE-CEILING TREATMENT
When Sound Travels Over the Wall
Suspended ceilings can leave adjacent rooms connected through the open plenum above.
In these conditions, upgrading the ceiling tile alone may not be enough. The treatment needs to address the path the sound is actually taking.
Depending on the existing construction and project requirements, Inaudible may incorporate additional above-ceiling treatments such as rigid acoustic insulation, barrier materials or other plenum-control details as part of the broader isolation strategy.
Plenum Barriers
Additional treatment above the visible ceiling can help reduce the open airborne path between adjoining spaces.
Rigid Acoustic Insulation
Rigid insulation can be incorporated into suitable above-ceiling treatments where additional absorption or assembly performance is required.
Barrier Layers
Where appropriate to the assembly, high-mass barrier materials can be combined with other treatments to address airborne transmission.
MECHANICAL SOUND
A Quiet Wall Cannot Fix a Noisy Duct
HVAC and other mechanical systems can carry noise around an otherwise strong partition. Air paths, shared ductwork, equipment vibration and openings through acoustic assemblies all need to be considered where privacy or low background noise is important. Depending on the condition, treatments may include duct silencers, isolation details, additional lining or coordination around penetrations and equipment connections.
Ductborne Noise
Noise carried through shared supply or return paths between spaces.
Equipment Vibration
Mechanical vibration transferred into walls, ceilings or surrounding structure.
Service Penetrations
Openings through acoustic assemblies that require careful treatment around the service itself.
DECOUPLING
Break the Rigid Path Before It Carries Vibration
When greater isolation is required, one strategy is to reduce the rigid connection between the finished surface and the structure supporting it. Isolation hangers, clips and channel systems can help separate the drywall from the framing so vibration has a more difficult path through the assembly.
The details matter. Fastener placement, perimeter conditions and transitions all need to preserve the intended separation rather than unintentionally reconnecting the surfaces.
Resilient Channel
A simpler decoupling method that can perform well when the specified installation details are followed correctly.
ISOLATION CLIP + FURRING CHANNEL
A more controlled decoupling system for higher-performing wall and ceiling assemblies, with less risk of accidental rigid connection than conventional resilient channel.
Isolation Hanger
A higher-isolation option for suspended ceilings where greater separation from the structure is required, particularly when impact or low-frequency vibration is a concern.
Spaces Where Privacy and Noise Control Cannot Be an Afterthought
Boardrooms & Executive Offices
Where confidential conversations need stronger separation from adjoining workspaces.
Medical & Therapy Spaces
Consultation and treatment rooms where speech privacy is part of the functional requirement.
Studios & Media Rooms
Spaces where isolation between production areas and neighbouring rooms is central to their use.
Multi-Tenant Commercial Interiors
Demising conditions where businesses need better separation from adjoining occupancies.
Hospitality & Guest Spaces
Rooms and shared environments where unwanted sound transfer can affect the customer experience.
Specialty & High-Privacy Spaces
Confidential rooms, legal offices and other interiors where ordinary partition construction may not satisfy the privacy objective.
WORKING WITH PROFESSIONAL TEAMS
From Acoustic Intent to Buildable Detail
Commercial projects may arrive with an acoustic engineer’s specification, an architect’s wall schedule or simply a known privacy problem that needs to be addressed before construction progresses. Inaudible helps translate those requirements into practical installation details and coordinates our acoustic scope with the surrounding framing, insulation, drywall and ceiling work. Where formal acoustic engineering, testing or stamped documentation is required, we work within the design provided by the appropriate project professional.
Builders & General Contractors
Practical installation input, scope coordination and execution within the construction schedule.
Architects & Designers
Coordination with specified wall, ceiling and interior assembly requirements.
Acoustic engineers
Installation of specified systems and careful attention to the details required to preserve the design intent.

Get the Acoustic Details Right Before Close-Up
Step 1
project Review
We review the drawings, project stage, noise concerns and available acoustic requirements.
Step 2
Identify the Critical Paths
Walls, ceilings, plenums, penetrations and mechanical conditions are considered in relation to the spaces requiring isolation.
Step 3
Define the Treatment
We establish the practical installation scope and coordinate it with the surrounding trades and project documentation.
Step 4
Install Before Close-Up
Isolation, insulation, sealing and related treatments are completed at the appropriate stage before the relevant assemblies are closed.
AFTER CLOSE-UP
Isolation Controls Transfer. Treatment Controls the Room.
Sound isolation and acoustic treatment solve different problems. Walls, ceilings and isolation assemblies are designed to reduce sound travelling between spaces. Once construction is complete, acoustic treatment can be added inside the room to reduce reverberation, improve speech clarity and create a more controlled listening environment.
Inaudible can incorporate both where the project requires them.
Pre-Construction Soundproofing FAQs
When should soundproofing be considered during a commercial build?
As early as possible when speech privacy or noise control is important. Framing, wall height, insulation, mechanical paths and ceiling conditions are easier to coordinate while the assemblies remain accessible.
What is acoustic isolation?
Acoustic isolation refers to construction methods intended to reduce sound transmission between spaces. Depending on the project, this may involve additional mass, decoupling, cavity insulation, perimeter sealing and treatment of flanking paths.
What is flanking noise?
Flanking transmission occurs when sound travels around the main separating wall or floor through adjoining building elements or junctions rather than directly through it. NRC Canada identifies flanking as an important component of the sound insulation actually experienced between rooms.
Can sound travel over a suspended ceiling?
Yes. When adjoining rooms share an open ceiling plenum, sound can travel above the partition. Ceiling-panel selection and above-ceiling conditions therefore need to be considered where room-to-room privacy matters. ¹Armstrong Ceilings
Do acoustic ceiling tiles soundproof between rooms?
Not necessarily. NRC and CAC describe different acoustic functions. High absorption inside the room does not automatically mean strong blocking through a shared plenum. Armstrong specifically distinguishes sound absorption from sound blocking in suspended ceiling systems.
Do you install isolation clips or hangers and resilient channel?
Yes. These systems can form part of wall or ceiling assemblies where decoupling is included in the agreed acoustic scope.
Can Inaudible work from an acoustic engineer's specification?
Yes. We can execute and coordinate specified acoustic assemblies within our trade scope. We do not provide stamped acoustic engineering reports.
Can you also complete the framing, insulation and drywall?
Yes. Those services can be coordinated with the acoustic scope where they form part of the same commercial project.
