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.

For more information, please refer to the device calibration and dynamic range specifications in the Tutorial section.

The calibrations and measurements sent to the OpeNoise community will be used for statistical purposes only and cannot be used in any way to verify compliance with legal limits.
