dB Meter: Measure Noise SPL

Measure decibel levels and see your noise history in real time — no setup, no account needed.

How loud is it, really? Point your iPhone at any room, street or venue and watch the sound level rise and fall on a live, color-coded meter — with plain-English labels so every reading makes sense.

WHAT YOU CAN DO • Read the level around you live, in decibels, on a smooth gauge • Track the now, average and peak of any moment • Run a timed session and save its min, average and peak dB • Keep a full history log you can name, note and revisit • Compare readings against a whisper-to-jet reference chart • Learn how loudness works and why it matters for your ears

HOW IT WORKS

1. Tap Start and hold your phone toward the sound
2. Watch the live trace and stats update in real time
3. Tap Stop to save the session to your history

AN HONEST NOTE This app uses your iPhone microphone, so readings are a helpful estimate — not a calibrated or certified instrument. Please don't rely on it for workplace, legal, occupational-safety or hearing-health decisions.

FULL ACCESS Unlimited saved sessions, the complete reference chart and the hearing guide unlock with a subscription — choose weekly, yearly or a one-time lifetime unlock.

Everything stays on your device. No account, no ads, no tracking.

Start listening to the world around you today.
