About OpeNoise

OpeNoise is a real-time noise level meter.


TECHNICAL SPECIFICATIONS:
- Real-time A-weighted sound pressure level measurement
- Minimum and maximum level
- Third octave and FFT analysis
- Data saving in text file
- Calibration

TERM OF USE
This app is not intended for professional use, it does not necessarily guarantee an accurate noise measurement.
Since each device has a different response to noise, a comparison with a professional noise level meter in the measurement dynamic range is required.
The utilization of the app requires adequate technical knowledge and skill; an extemporary measurement might not be correct.
