Decibel Meter: NoiseScope

NoiseScope is a personal environmental noise analyzer for real-time sound measurement, sleep environment review, and long-term noise records.

Open the app and measurement starts automatically. You can check current dB levels, peaks, LAeq trends, weighting modes, response modes, low-frequency indicators, and noise profile insights in a focused full- screen interface.

Key features:

• Real-time decibel measurement
• LAeq, peak, A/C/Z weighting, and Fast/Slow/Impulse response
• Sleep noise analysis with baseline, peak, disturbances, and quiet periods
• Hearing exposure estimates based on NIOSH and OSHA references
• Noise profile insights for low-frequency rumble, traffic, mechanical noise, and sudden events
• Local history with session summaries and event timelines
• PDF reports for single sessions, 24-hour trends, and sleep review
• Microphone profiles, calibration tools, and device model adjustment
• Local-first data storage with no raw recording upload by default

Free features include real-time measurement, basic trends, single-session reports, and recent history. Pro is a one-time purchase that unlocks advanced reports, sleep analysis, full history, calibration tools, alerts, and data archive features.

NoiseScope is designed for personal reference, room comparison, sleep environment review, apartment noise checks, office noise tracking, and daily sound awareness. It is not a replacement for a certified legal sound level meter.
