Soundmeter - High-Precision Decibel Meter & Noise Analyzer
Overview Soundmeter is a professional-grade real-time environmental noise measurement tool that accurately captures sound levels (dB) via smartphone built-in microphones. Designed to monitor noise pollution and optimize living or working environments, it provides actionable insights for home soundproofing tests, study space monitoring, and industrial safety compliance.
Core Features Real-Time Decibel Measurement Displays noise levels in numeric values and dynamic waveform charts with millisecond updates. Device-specific calibration function ensures measurement consistency across Android devices. Contextual Noise Reference Compares measurements to common scenarios (e.g., Library ≈30dB, Traffic Intersection ≈80dB) with color-coded safety indicators (green/yellow/red). Smart Alert System Customizable threshold alerts for hearing protection, aligned with WHO-recommended exposure limits. Technical Highlights Standard-Compliant Algorithm Optimized using IEC 61672 standards to minimize hardware variability impacts. Low-Power Operation Background monitoring consumes minimal battery (＜5% per hour in testing). Cross-Device Compatibility Supports Android 8.0+ and mainstream brands (Samsung, Xiaomi, Huawei). Use Cases Households & Individuals Evaluate indoor/outdoor noise pollution and protect infants/pets from sudden loud sounds. Workplaces & Industrial Sites Monitor open-plan offices or factory floors for OSHA-compliant noise levels.
