Sound Level Check: dB Meter

"Sound Level Check is a simple, private decibel meter and sound level meter that measures environmental noise in real time. Check sound levels, monitor dB(A) measurements and understand how loud your surroundings are.

Use your phone as a sound meter at home, in the office, outdoors, at concerts or near traffic. No sign-up or audio recording required.

REAL-TIME SOUND METER

Measure environmental noise with live dB(A) readings.
View sound levels on a smooth analogue gauge.
See large, continuously updated decibel values.
Track noise changes with a rolling 30-second graph.
Monitor minimum, average and maximum dB levels.

SOUND LEVEL REFERENCE

Understand your decibel measurements with a built-in sound reference chart. Explore everyday sounds from a whisper (30 dB) to a jet takeoff (130 dB). Your current reading is highlighted as it changes.

SIMPLE DECIBEL CALIBRATION

Every phone microphone is different. Compare your sound meter against a reference sound level meter and adjust the calibration offset.

Simple +/- calibration adjustment.
Live preview of calibrated readings.
Easy device-specific sound measurement calibration.
SOUND MEASUREMENT HISTORY

NOISE LEVEL ALERTS

Set a custom noise threshold and receive a vibration alert when your surroundings exceed your selected dB(A) level.

An 85 dB threshold is commonly used as a reference point in hearing-safety guidance.

PEAK HOLD

Keep the loudest measured sound level visible while the sound meter continues running. Monitor sudden noise peaks without interrupting measurements.

PRIVATE SOUND MEASUREMENT

Your privacy matters.

IMPORTANT MEASUREMENT NOTE

Phone microphones are designed primarily for voice capture and may vary in sensitivity and frequency response. Very loud sounds may exceed your device's measurement capabilities.

Sound Level Check is a helpful sound level and noise measurement tool, not a replacement for a professionally calibrated SPL meter.
