Audio Chambers
Audio chambers for repeatable speaker, microphone, headset, and voice-assistant characterization: low-noise environments engineered to make sensitive measurements reproducible.
Request a QuoteWhy Do Audio Measurements Need an Audio Chamber?
An audio chamber is a low-noise, sound-isolated space that removes the room itself as a test variable, so audio measurements stay repeatable across runs, days, and product cycles. 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.
Novus Labs deploys audio chambers inside our audio validation lab for precisely this purpose. Paired with calibrated reference instrumentation, they 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. These chambers anchor our broader audio testing program.

- Signal-chain isolation
- Distributed-audio characterization
- Speakers, microphones, headsets
- Frequency response measurement
- Sensitivity and noise-floor
- Wake-word reliability
- Far-field voice pickup

- Background-noise control
- Calibrated reference instrumentation
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 chamber 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 built an audio chamber 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.

What is an audio chamber?
An audio chamber is a low-noise, sound-isolated room that removes ambient noise and reflections as variables, so audio measurements are repeatable. Novus Labs runs audio chambers alongside calibrated reference instrumentation for speaker, microphone, headset, and voice-assistant testing.
What do you test in the audio chambers?
Audio glitch and dropout detection, transducer characterization (speakers, microphones, headsets), far-field voice and wake-word pickup, and reference calibration. These feed the broader audio testing program.
Can you test wireless audio products in the chambers?
Yes. We built an audio chamber inside one of our RF-shielded chambers, so wireless speakers and Bluetooth headsets can be characterized for audio and RF behavior at the same time.
Do you also validate audio in real-world conditions?
Yes. When a product needs to prove itself outside the lab, we extend testing into our residential test homes for real walls, real Wi-Fi, and real interference.
