Shaping Sound in Built Environments
OCTAV provides consulting services in architectural acoustics. Our team works closely with project architects, engineers, and stakeholders to deliver sound environments that align with functional and design objectives across a range of building types and sectors.
We support each project with a disciplined, evidence-based approach to acoustic analysis, design, and documentation. Whether working on a quiet workplace, a high-performance learning space, or a critical listening environment, we focus on delivering technically sound, practical solutions that integrate seamlessly with the broader project goals.

Markland Wood Golf Club, ON
Reverberation Control
Patrons at Markland Wood GC were experiencing poor acoustic conditions in the clubhouse, where excessive reverberation made conversation difficult. OCTAV did an acoustical assessment and designed targeted treatments. Post-install measurements confirmed a significant improvement, and patrons immediately noticed a more comfortable environment.

Altstadt Brewery
Fredericksburg, TX
Reverberation Control
The Great Hall at the Altstadt Brewery experienced significant noise issues during busy events due to excessive reverberation in the large, open space. OCTAV was engaged to assess and address the acoustical challenges. Our team conducted detailed acoustical measurements to characterize the reverberation problem, then developed a tailored treatment strategy to improve sound clarity and comfort. We also provided installation-ready layout drawings to support the implementation of the acoustical solutions.

Our Services
Speech Intelligibility (STI/STIPA)
We measure and optimize speech intelligibility (STI/STIPA) for PA systems, performance venues, and critical announcements, enhancing clarity and understanding.
Office Sound Masking & Privacy
Sound masking solutions reduce distractions and enhance speech privacy, boosting productivity and comfort for open-plan and private workspaces. We can help you specify and select a sound masking system.
Electroacoustic Modelling & Auralization
Hear your space before it’s built. Our advanced 3D acoustic modelling and auralization services allow you to experience and refine the sonic environment during the design phase.
Critical Listening Space Design
We design recording studios, control rooms, and high-fidelity listening spaces ensuring accurate sound reproduction and an uncompromised auditory experience.
Architectural Acoustic Analysis
We analyze reverberation (RT60), modal response, and material properties using advanced modelling to shape listening conditions for any space.
Sound Insulation Testing (STC/IIC)
Quantify and improve sound isolation between spaces. Our STC (airborne) and IIC (impact) testing measures partition performance, crucial for privacy, comfort, and building code adherence.
HVAC & Mech. System Noise Control
We review, measure (NC/RNC), and design mitigation strategies for HVAC and mechanical noise, to improve acoustical comfort in interior environments.
Audiovisual Integration & Acoustic Optimization
We integrate audiovisual systems with room acoustics, to improve performance, clarity, and immersive experiences for any presentation or media space.
Why Work with Us
We apply the precision of acoustic engineering with an understanding of how buildings are actually constructed and used. Our team brings practical experience across various sectors and project scales, with careful attention to detail and context. We start by listening – taking the time to understand design goals and technical constraints, so our recommendations align with both acoustic performance and construction feasibility.
As part of OCTAV, we’re also equipped to coordinate acoustic and AV planning when needed. This connection supports efficient integration and streamlined collaboration on projects where both disciplines intersect.
Real experience. Real satisfaction.
Meet our team who make it happen.
