About this app

Measure relative microphone noise and illuminance, and keep site records.

• Noise in dBFS and light in lx, averages, maxima and trends
• 30-second, 1-minute, 5-minute or manual sessions
• Locations, conditions, photos, actions and remeasurement results
• Compare records from the same point, search and restore from trash
• Share selected PDF/image reports and back up records with photos to ZIP
• Language selection and manual offset calibration

Uncalibrated noise is relative microphone input in dBFS. Manual calibration provides estimates. Use a calibrated dedicated instrument for precise sound-pressure measurements and legal evaluation. Light measurement requires a device light sensor.

Original audio is not saved. Records and photos stay on your device until you choose to export them. Intended for adults aged 18 and over. Ads may appear when opening the app.

What’s new

Fixed an issue where the age selection option was not displayed on first launch, preventing app use. You can now use measurements even if you cancel the age verification screen.
