Audio Chambers
Acoustic isolation chambers for repeatable speaker, microphone, headset, and voice-assistant characterization — low-noise environments engineered to make sensitive measurements reproducible.

Sensitive audio measurements live or die by the consistency of the environment around them. Even small fluctuations in ambient noise, HVAC output, or stray foot traffic can corrupt a transducer characterization or skew a glitch-detection run. Audio chambers eliminate the room itself as a test variable so results stay reproducible across runs, days, and product cycles.
Novus Labs deploys acoustic isolation booths inside our audio validation lab for precisely this purpose. Paired with calibrated reference instrumentation, the chambers give engineers a controlled space to isolate the device under test from the world around it — whether the goal is hunting an intermittent audio glitch, measuring a microphone's true noise floor, or characterizing a smart speaker's far-field pickup.

Audio Isolation Inside an RF-Shielded Chamber
Wireless audio products — smart speakers, Bluetooth headsets, voice-enabled hubs — need to be characterized for both acoustic behavior and wireless behavior, often at the same time. Testing them in a standard audio booth leaves the RF environment uncontrolled; testing them in a standard RF chamber leaves the acoustic environment uncontrolled. Neither alone gives a complete picture.
Novus Labs has installed an acoustic isolation booth inside one of our RF-shielded chambers to solve this. The hybrid setup gives engineers simultaneous audio isolation and wireless shielding in a single test space — ideal for characterizing wireless headphones, smart speakers under intentional RF interference, or any voice product where audio and wireless behavior have to be measured together.
