NoiseGuard - Your Personal Environment Noise Monitor
Monitor your environment's noise level in real time, record audio sessions, and track noise trends — all in one beautifully designed app. Whether you're protecting your hearing, optimizing your workspace, or documenting noise pollution, NoiseGuard gives you the data you need.
NoiseGuard uses your device's microphone to measure ambient noise levels and displays them on an intuitive gauge. Record sessions to capture audio evidence, review detailed statistics, and export your data for analysis.
Key Features:
• Real-Time Monitoring: See your environment's noise level instantly with a live decibel gauge and color-coded status indicators
• Audio Recording: Record noise sessions with automatic saving and playback, complete with dB change curves
• Smart Alerts: Set custom noise thresholds and get notified when levels exceed your limit — with popup, vibration, or sound alerts
• Do Not Disturb: Schedule quiet hours so alerts won't interrupt your sleep or meetings
• History & Trends: View daily, weekly, and monthly noise trend charts to identify patterns
• Location Tracking: Automatically record GPS coordinates with each measurement
• Data Export: Export your noise data as CSV reports with timestamps, decibel levels, and location data
• Microphone Calibration: Fine-tune measurement accuracy with offset calibration
