Engineered with precision and styled with a sleek, modern visualizer, dB Meter Pro gives you lab-quality insights right in your pocket. KEY FEATURES: Real-Time Decibel Metering: Get instant, high-precision readings of current, average (Leq), minimum, maximum, and peak sound levels. Professional Frequency Weighting: A-Weighting (dBA): Standard for human hearing response and environmental noise assessments. C-Weighting (dBC): Ideal for measuring low-frequency mechanical and industrial noise. Z-Weighting (dBZ): Flat, unweighted acoustic response for raw analysis. Time Weighting Modes: Toggle between Fast (125ms) for rapid transients and dynamic sounds, and Slow (1s) for stable average readings. Interactive Real-Time Graph: Visualize noise history in a zoomable, scrollable timeline. Trace trends and identify sudden noise spikes instantly. Advanced Calibration: Calibrate the app’s readings using a reference sound level meter to guarantee maximum precision across different Android hardware. Decibel Reference Guide: Not sure what 75 dB means? Our built-in reference chart matches readings to real-world sounds (e.g., quiet library, city traffic, lawnmower). Premium OLED Dark Mode: A stunning, low-energy dark theme that saves battery life during overnight or long-duration recordings.
