Sound Meter & Noise Detector

A sound meter app gives you precise control over your acoustic environment, protecting your hearing and peace of mind wherever you are. Sound Meter & Noise Detector transforms your device into a professional-grade noise measurement tool, delivering real-time decibel readings that help you identify and manage harmful sound exposure before it affects your health and rest.

Understand your noise environment with comprehensive, accurate data. The app displays minimal, average, and maximum decibel levels simultaneously, with both real-time dial and graph visualizations so you can see exactly how noise fluctuates in your space. A noise level indicator helps you quickly assess whether ambient sound falls within safe ranges. Calibration before use ensures precision tailored to your device's microphone performance—a critical step for reliable noise detection that accounts for hardware variations across different phones and tablets.

Capture and review your acoustic history with full recording capabilities. Save audio files during measurements for later analysis, replay previous recordings to compare patterns, and access detailed measurement histories including duration, timestamps, and measurement status. This feature-rich approach lets you track noise trends over time and build evidence for addressing persistent problems in your home, workplace, or study area.

Customize alerts and appearance to suit your needs. Set decibel warning thresholds that trigger sound or vibration notifications when noise exceeds your preset limits—ideal for sleep-sensitive environments, noise-sensitive work, or health-conscious households. Toggle between black and white themes depending on your preference, and control how you receive alerts so warnings integrate seamlessly into your routine without jarring interruptions.

Manage your recordings with ease. Rename files for quick identification, share measurements with others to document noise issues, restart or suspend measurements mid-session, and maintain full control over your data. The app respects your workflow by letting you work at your own pace while preserving all recordings you choose to save.

Important: Calibrate your device before taking measurements for accuracy, as microphone performance varies between devices. Adjust calibration based on your experience or validate against a reference sound meter for maximum precision. Always save recordings before closing the app to preserve your measurement data. Sound Meter & Noise Detector empowers you to make informed decisions about your acoustic environment and take action to protect your wellbeing.
