Abstract After a reminder that the decibel is not a unit, but a way of counting which can be applied to any quantity, the author of this booklet studies the physical measurements of a source of noise (sound pressure level, acoustic power), so-called subjective measurements, assessment of annoyance or harmful effects of steady-state noise, and influence of noise duration or other parameters. Index of commonly used units.
