Test your conference room audio in 60 seconds

Stand in the room, clap three times, and get an approximate RoomScore with your room’s reverberation estimate, how it affects video calls, and what to fix first.

Uses your microphone for ~20 seconds

Stand near the middle of the room with the device 30–50 cm from your hands, clap hard three times about two seconds apart, and stay quiet in between. Built-in mics work best; take headphones off.

Private by design. The microphone is used only for this test. Audio is analyzed locally in your browser — nothing is recorded, stored, or uploaded. When the test ends, the microphone is released.

This is a screening tool, not a certified acoustic measurement. Phone and laptop microphones vary; results are approximate. Have an iPhone 12 Pro or newer? The free RoomScore app does the full audit with LiDAR room geometry and a PDF report.

On a laptop? This works best on a phone held near the middle of the room — open roomscore.tech/test on your iPhone. Or skip the claps: the free RoomScore app measures the room with LiDAR and guides each clap.

What to do next

Turn this estimate into a real audit (10 minutes, iPhone)

LiDAR scans the room, so the score and target use your real volume instead of a size preset.
You get the treatment plan with panel area, an AI check of your mics and speakers, and a PDF report for your boss or your AV vendor.
Optional Zoom test call to prove the fix worked.

Free. Needs an iPhone 12 Pro or later, or an iPad Pro (2020+), on iOS 17 — the Pro models carry the LiDAR sensor. App Store: US, Canada, UK, Switzerland. Any phone can run this browser test.

Add this measurement to the community dataset. We'd store the numbers shown above (RT60, background-noise rating, score, room size, and the measurement-quality grade) plus the date and a coarse browser/platform label. No audio, no name, no email, no precise location. It helps the benchmarks every visitor sees. Once saved, the numbers can't be traced back to you, so they can't be removed individually.

Your room’s measured decay

Energy decay after your loudest clap, with the regression line used to estimate RT60.

What would acoustic panels do?

Drag to add absorption and watch the predicted reverberation respond — same Sabine/Eyring simulation as the RoomScore app.

Predicted RT60–

Predicted score–

Screening estimate from your device microphone — not an ISO 3382 measurement. Reverberation (RT60) is estimated from clap decay using the same T20/T30 analysis as the RoomScore app; the score uses RoomScore’s standard acoustic scoring. Background-noise rating is approximate because browser microphones are not calibrated.
