Sound Meter & dB Decibel Meter

Sound Meter shows how loud it is around you, in real time. The live meter is free, with no time limit, no ads and no account.

FREE, NO TIME LIMIT
• Live decibel reading with min, average and max
• 60-second level chart
• Everyday reference levels, from a whisper to a rock concert
• Calibration offset (±20 dB in 0.5 dB steps)

PRO (OPTIONAL)
• Save every session, name it and compare nights
• Export PDF noise reports and CSV data, for example a noise log for your landlord
• Alerts when the level goes above a threshold you choose (while the app is open)

ON IPHONE AND IPAD
A big, clear readout on iPhone, and a roomy layout on iPad with your history alongside.

PRIVATE BY DESIGN
Sound is measured on your device. Audio is never recorded or uploaded. Only the numbers you choose to save are kept, on your device.

ABOUT ACCURACY
iPhone and iPad microphones are not calibrated sound level meters. Readings are approximate, vary by device and case, and are not suitable for legal, medical or occupational-safety compliance. Use a calibrated Class 1 or 2 meter for official measurements.
