Sound Meter Pro: Decibel Meter

Sound Meter Pro turns your phone into a practical decibel meter for everyday noise checks. See sound levels in dB, follow changes around you and save measurement sessions for later. MEASURE THE SOUND AROUND YOU Check noise at home, around appliances, in your workspace or on a busy street. A clear sound level display helps you compare environments using the same device. FOLLOW CHANGES OVER TIME Watch the live graph and review minimum, average and maximum readings. Save measurement sessions and return to your history when you need to compare results. EXPLORE YOUR MEASUREMENTS View frequency analysis and adjust the sensor offset using a reference sound level meter. Choose English, Spanish, Portuguese, Russian, Hindi or Chinese in the app settings. UNDERSTAND THE LIMITS Phone microphone readings are estimates. Accuracy and measurable range vary by device, microphone and calibration. Sound Meter Pro is not a certified sound level meter and must not be used as a substitute for professional equipment or for legal, medical or workplace compliance decisions. Start with a simple question: how loud is it here?

New design, clearer live sound levels and easier session recording. Improved history upgrades and measurement display.
