The Ear, Hearing and Hearing Impairment: Bang as aperiodic sound impulse

Video (00:03 minutes):
Example of an extremely short loud aperiodic sound event. Graph can be seen on oscilloscope!

A bang is the result of a sudden, very short aperiodic vibration of great amplitude. The amplitude diminishes quickly as well.
Examples are a shot, the bursting of a paper bag or the banging of a door.

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
