Sound frequency sensor

The wireless sensor records the frequency of sound vibrations and transmits the data to a digital laboratory system. It supports six experiments: determining the frequency of sound of tuning forks, strings and sound generators, studying the relationship between pitch and vibration frequency, studying the resonance of an air column and standing waves in pipes, the dependence of the vibration frequency of a string on its length and tension, observing beats when adding sounds of similar frequencies and demonstrating the Doppler effect. The sensor is used for activities on acoustics and vibrations in physics courses.
