The Ear, Hearing and Hearing Impairment;: Tuning fork as "simple" sound

Example of a simple periodic sound signal is the relatively pure sound of a tuning fork.

The pure periodic sound is the simplest sound event. It corresponds to a regular sine vibration (= harmonic vibration) of pure frequency. The sound of a tuning fork is the nearest of all non-synthetic sound sources to this ideal.

Information and ideas:
Recording to illustrate different sorts of sound (or students have to identify them).

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