Decibel Meter Sound Detector is a highly efficient app that helps you track environmental noise around you. This app is available on the iPhone platform and is free to download. With this app, you can transform your device into a professional-grade sound detector. The app uses the built-in microphone to determine the level of sound and displays it in decibels (dB). This app supports polling functionality using web hooks to monitor the dB and frequency values for real-time data analysis.

The Decibel Meter app supports sharing readings with Messages, Email, WhatsApp, Notes, and more, if the user prefers to use dB/AF values for further analysis. The app does not collect, use, store, transmit, or circulate any audio or other information. The decibel reading obtained from this application is limited to the device microphone capabilities and is not recommended for professional-grade metering. Additionally, the audible frequency range is limited to 20 to 16,000 Hz.

This app has an intuitive design and features accurate measurements, frequency weighting A, B, C, Z, threshold settings, and displays current, average, and maximum values. The app also displays peak frequency and has calibrated with a professional quality dB measurement device. The manual calibration feature allows users to calibrate the app as per their requirements. The start/stop/reset functionality enhances the user experience.
