Measure of noise intensity
#1
Hello,
I want to use Phyphox Noise Intensity with my students but I don't understand why the measures (SPL db) are always negative. Is it because the sensor is not calibrated ? How can I get positive values without calibrating the sensor ?
Thank you for your help.

The audio amplitude experiment could only provide relative intensity information if the sensor is not calibrated. So: yes – and you can‘t. Please find some details in the experiment info via the three vertical dots menu.
