About This Product
A tuning fork, speaker or bell sounded near the microphone produces a signal that can be watched on an oscilloscope, making the link between sound energy and electrical energy visible. It suits lessons on transducers, sensors and frequency response, and practicals that compare signals from louder or higher-pitched sounds. Educational Instrument can arrange export supply of the Piezoelectric microphone to Brunei, Georgia, Papua New Guinea, Serbia and Sri Lanka.
