Soundmeter

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.
