DeciGuard is a professional acoustic sound level meter and legal noise evidence reporter engineered for precision, reliability, and peace of mind.
Unlike generic sound meters that only display raw numbers, DeciGuard combines medical-grade acoustic monitoring with legal-grade documentation, empowering you to measure, log, and generate authoritative compliance reports in one tap.
KEY FEATURES:
• Calibrated Sound Level Meter: Precision dB SPL metering with both A-Weighting (human ear response) and C-Weighting (low-frequency rumble).
• Real-time Waveform Visualizer: High-frequency pressure wave rendering with dynamic threshold indicators.
• Long-Term Evidence Logging: Run continuous monitoring sessions to compute Equivalent Continuous Sound Level (Leq), peak spikes, and over-threshold durations.
• Noise Spike Tagger: Timestamp and annotate sudden disturbances (e.g., slamming doors, construction drilling) directly into your evidence log.
• Authoritative PDF Report Generator: Export comprehensive PDF reports complete with hardware fingerprints, timeline vector charts, statutory standard evaluations (GB/WHO/OSHA), and signature verification blocks. Ready for AirDrop, email, and AirPrint.
• 100% On-Device & Private: Zero audio recordings stored, zero cloud transmission. Audio is processed purely on-device for total privacy.
PERFECT FOR:
- Documenting neighbor noise disputes and lease violations
- Monitoring nursery or bedroom quietness for optimal sleep
- Assessing workplace OSHA noise compliance
- Acoustic calibration for home studios and audio setups
