Description:
A sound event with irregular (aperiodic) form of vibrations is described as sound. It is made up of many individual vibrations, the frequencies of which are not in integral relation to each other.
The rustling of paper or road traffic are examples.
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
