Description

This is a support page for the teaching activity about the resonance of acoustic systems. It can generate a sound with a linearly variable frequency for a given duration.

The page also measures the sound intensity picked up by the microphone. The intensity is linearly proportional to the integral of the squared signal (i.e. it is not calculated in decibel). Before measuring the intensity, the signal is filtered with a Single Pole Recursive Filter in a low-pass configuration. The measured intensity is averaged over a given period of time.
