Every room has a sound. We measure it before it is built.
Tune the dimensions and surfaces of a room below and hear the reverberation it produces — the same image-source modelling and reverberation-time calculation we run for every project, in your browser.
Coefficients approximate the 500 Hz octave band and treat all four walls as one surface — a fair conceptual estimate, not a substitute for the full octave-band survey a commissioned study receives.
Four disciplines, one measurement
Acoustics is one problem wearing four hats. We work all four, usually at once.
Room acoustics
Reverberation, clarity and envelopment — tuned by geometry and surface treatment, not bolted on afterward.
Noise control & isolation
Keeping a room's sound out of the next one, and the street's sound out of this one.
Mechanical system noise
HVAC, transformers and generators specified against a background noise target before they are purchased, not after they are heard.
Electroacoustic design
Loudspeaker layout and coverage modelled against the room's own acoustics, not sold as a generic package.
The model comes before the material list
Every project starts as a set of numbers before it is a set of finishes: room volume, target reverberation time by frequency band, and a background-noise criterion the mechanical engineer has to hit.
Materials get chosen to satisfy those numbers, not the other way around. It is a slower way to start a project and it is the only way that reliably survives contact with a finished room.
Rooms we have measured into shape
A recital hall, a podcast studio, an open-plan floor that stopped sounding like a food court — different problems, the same method.
Bellwood Recital Hall
A 420-seat recital hall built to hold a solo cello and a full choir equally well, without touching a single curtain in between.
Meridian Sessions Studio
A room-within-a-room isolation build for a studio sharing a wall with a working restaurant kitchen.
Kepler Podcast Studio
A compact two-host isolation booth designed to fit inside an existing office suite.
Anders & Cole Headquarters
An open-plan floor redesigned around speech privacy after the noise complaints stopped being occasional.
Saltline Rooftop Restaurant
A rooftop dining room brought down from a shout to a conversation without losing the room's energy.
Holt Memorial Chapel
A century-old chapel where the organ needed the reverberation and the sermon needed the opposite.
What it sounds like afterward
“They gave us a target reverberation time before the walls existed, and the finished hall landed within a tenth of a second of it. I have sat through enough acoustics consultations to know how rare that is.”
“We share a wall with a kitchen that runs past midnight and a residential floor above us. Two years in, nobody on either side has ever mentioned hearing us track a session.”
“Our acoustic complaints were the top line item on every employee survey for a year. After the ceiling and focus-room work, they dropped off the list almost entirely.”
