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.
