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

model adjustment
- Local-first data storage with no raw recording upload

Free features include real-time measurement, basic
trends, single-session reports, and recent history. Pro

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.

meter.
