Sound speed model

Using this sound speed model, the student is autonomous, they vary the distance between the speaker and the microphone, and they read in real time the sound wave's travel time. The sound is only emitted when the "sound emission" button is pressed, allowing the different poles to work without constraints. Place the receiver in front of the transmitter. Measure the distance between these two points. Note the time on the display for each distance. Calculate the distance/time ratio; verify that the ratio is a constant. Compare the obtained value to the theoretical value of the speed of sound. Discover the connected version compatible with mobile devices such as tablets: Connected sound speed model.
