Video - Model: Speed of sound

The speed of sound models allow to easily demonstrate the proportional relationship between the sound propagation time and the distance between the speaker and the microphone. The display of the model allows for simple and fully autonomous measurements. The connected version incorporates all the advantages of the speed of sound model by integrating a wifi router to connect to a tablet or smartphone, for example. An application launches without installation by going through an internet browser. This application allows to control the model, plot a graph, and finally model the curve.
