Basically, a bang is an abrupt, mechanical, aperiodic oscillation of very short duration and large amplitude. The amplitude also decays quickly.
Examples are a gunshot, bursting of a paper bag or a door slamming shut.
Information and ideas:
Possible cross reference: Examination of aperiodic speech signals with the help of spectral analysis.
