About 45dB Systems
Australian sound masking specialists
45dB Systems designs, supplies, installs and commissions sound masking systems for Australian workplaces.
We work with architects, acoustic consultants, builders and workplace teams to improve speech privacy, reduce distraction and create comfortable acoustic environments.
From the first floor plan to final calibration, our role is to make the system work as part of the finished space.
Experience on major Australian projects
From university spaces to commercial towers
Our project portfolio includes 1 Elizabeth, Barangaroo, Westpac, ANU, Monash and CBA.
At 1 Elizabeth in Sydney, we delivered more than 3,000 speakers across 27 floors in a centrally networked system.
Built around the acoustic brief
We develop the layout, zoning and control approach around the way the workplace will be used.
Coordinated with the project team
Speaker placement, ceiling types, services and construction details are considered together with architects, acoustic consultants and installers.
“To me sound is everything - without it we’d be lost. Being able to harness that energy and use it to create a mood, space or feeling inspires me. Why do I do what I do? For the love of sound.”
— Tom Hardy, Founder 45dB
Technology with practical control
We use Soft dB technology for automatic calibration, optional adaptive masking and networked zone management.
Commissioning turns the design into a working system. We calibrate the sound for the finished space and support adjustments as layouts and working patterns change.
For the love of sound
Tom Hardy, founder and principal of 45dB Systems, brings experience across sound, furniture and workplace design.
His focus is practical: helping project teams create spaces where people can collaborate and concentrate comfortably.
