Speed of Sound
01 Speed of Sound in Air Read Sound is a vibration that travels through an elastic substance. The stiffness of the material will affect the attenuation of the sound and the speed at which it travels through the material. Reference sources will give a value of 333.1 to 331.6 m/s at 0ºC for the speed of sound in air, temperature has a significant effect. In the experiment you arrange a pair of microphones to receive a sound from a point source, but at different distances from the source.

Connect to input 1
Use clamps to hold the sensors at the same height above the bench top. Check by sight that they are in line. The sensors should be at right angles to the bench top, parallel to each other and facing the noise. A clap of the hands is usually sufficient to produce a measurable sound.
What you need 1.
