Decibel Meter with Alarm

See an approximate sound level, set a threshold, and get an alert when the noise stays above it. Decibel Meter with Alarm combines a clear live dB meter, threshold alerts, and private session summaries. MEASURE LIVE SOUND LEVELS • View current and peak estimated dB readings • Follow a simple live session on your phone • See when the selected threshold is reached • Stop a measurement at any time CREATE A NOISE ALARM • Choose the dB threshold that matters to you • Get a clear local alert while a session is active • Use the meter for room checks, study spaces, workshops, and everyday comparisons KEEP MEASUREMENTS PRIVATE • Microphone access is used to calculate a sound-level estimate • Audio is not saved or uploaded by the default workflow • Readings and session counts remain on this device HONEST DEVICE MEASUREMENTS Phone microphones, cases, distance, frequency, and room acoustics affect results. The app shows an approximate level, not a certified sound-level measurement. Calibration and comparison with a trusted reference can improve consistency between sessions. IMPORTANT LIMITATIONS Do not use this app as the only source for occupational safety, medical, legal, regulatory, or hearing-protection decisions. Use a calibrated professional instrument when accuracy is critical. The meter does not record conversations by default and cannot guarantee an exact dB value on every device. Start a session, set the level that matters to you, and know when the room stays louder than expected.
