What is LMIN?
LMIN, or Minimum Sound Level, is the lowest sound pressure level recorded during a measurement period.
What’s the quietest point during a noise measurement?
It shows the quietest moment in a given timeframe, giving useful context for background noise levels or pauses in otherwise noisy environments.
LMIN is typically used alongside metrics like LMAX and LEQ to give a fuller picture of how noise levels vary. It’s especially relevant in environmental noise monitoring, where understanding baseline conditions is just as important as capturing peak events. In this video, we explain what LMIN tells you, when it’s useful, and how it fits into broader acoustic assessments.
