How it's used
Scientific and technical contexts are where this term primarily lives, functioning as a standard unit of measurement for sound intensity. While it is a loan translation from English, it is fully integrated into everyday Cantonese when discussing noise pollution, audio equipment, or hearing protection. It is rarely used in casual conversation unless the topic specifically turns to volume levels or technical specifications.
Examples
