The Ear, Hearing and Hearing Impairment: Test tone as purest sound signal

Video (00:04 minutes):
A simple monofrequent pure tone produced synthetically with a generator is a very pure tone. The video shows the oscilloscope graph.

A simple monofrequent pure tone produced synthetically with a generator can be even purer than any tuning fork tone.

Information and ideas:
Suitable for demonstration purposes but also good for self-study on the part of the students. Idea: show the film without sound to begin with. The students should then guess what sort of noise/sound it might be.

Relevant for teaching:
Acoustic phenomena
Sound/acoustics: parameters
Communication and understanding
Vibrations and waves
