Description
Turn your phone into a professional sound meter, decibel meter (dB meter), SPL meter, and noise analyzer. Measure ambient sound levels in real time, monitor noise pollution, and analyze acoustic environments with accurate, privacy-first audio measurement tools.
Whether you're checking room noise, workplace sound levels, speaker volume, construction noise, or environmental decibels, Sound Meter Pro delivers fast, precise readings with advanced calibration and professional-grade visualization.
🚀 Key Features
📈 Accurate Real-Time Decibel Meter Live sound level meter (SLM) readings using your device microphone Precise Sound Pressure Level (SPL) measurement in dB / dBA / dBC / dBZ Monitor Current / Average / Peak (Max) sound levels instantly Detect quiet background noise or sudden loud spikes
🎛 Professional Meter Display High-fidelity analog decibel gauge with needle response Large digital dB display for quick reading Smooth real-time scrolling noise graph to track trends Black & White gauge mode for high-contrast viewing
🔬 Advanced Acoustic Analysis
Standard Weighting Modes A-Weighting (dBA) – Matches human hearing sensitivity; standard for environmental noise. C-Weighting (dBC) – Flat response for loud machinery and peak sound analysis. Z-Weighting (dBZ) – Zero (flat) weighting; pure physical sound pressure.
Professional Time Response Energy-Based Averaging (IEC 61672-1) ensures response matches laboratory-grade equipment. Fast (125ms) – Precisely catches quick sound spikes and sudden noises. Normal (350ms) – Balanced monitoring for general use. Slow (1000ms) – Highly stable readings for steady noise monitoring. Custom – Fully adjustable from 50ms to 2000ms.
🛠Complete Customization & Calibration
Auto-Calibration Identifies your device's internal "noise floor" (electrical noise) Eliminates "fake" sound activity in silent environments Improves accuracy for low-level measurements
Manual Precision Tuning dB Offset: Adjust readings ±20 dB to match professional reference meters. Max Ceiling: Define the upper dB limit (90-120 dB) to match your microphone's hardware capability. Display Update Rate: Adjustable refresh (33ms - 500ms) to balance smoothness and battery life.
Saved Calibration Profiles Quickly switch between "Internal Mic," "External Mic," or "Reference" settings. Save unique offsets and weighting preferences for different hardware setups.
🔒 Privacy & Performance 100% on-device audio processing – no recordings, no uploads. Screen Wake Lock – prevents screen from turning off during long measurements. Haptic Feedback – subtle physical response for interactions. Dark & Light mode support.
💡 Perfect For: ✔ Measuring home & office noise ✔ Checking factory / workshop sound levels ✔ Testing home appliance & HVAC noise ✔ Speaker & home theater calibration ✔ Monitoring neighborhood & street noise ✔ Educational acoustics experiments
Important: Sound Meter Pro is highly accurate for a mobile app, but phone microphones are not certified laboratory instruments. For legal, compliance, or life-safety acoustic reporting, use certified professional equipment.
