Silence and noise level meter
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Measure the sound levels around you in real time.
Decibel Meter turns your iPhone into a sound level meter. Point your device at any sound source and get instant dB SPL readings displayed on a clear circular gauge with a live-updating chart.
REAL-TIME MEASUREMENT
See your current sound level update 10 times per second. The circular gauge changes color to indicate safe, moderate, and dangerous noise levels at a glance.

Track how sound levels change over time with a continuously updating line chart. Free users get a 15-second window; Pro users can extend it to 30 seconds, 1 minute, 2 minutes, or 5 minutes.
SESSION HISTORY
Save your measurement sessions and review them later. Each saved session includes average, minimum, maximum, and peak dB levels along with a visual sparkline of the recorded data.
PRO FEATURES

PRIVACY FIRST
All audio is processed entirely on-device. Nothing is recorded, stored, or sent anywhere. Period.
