pressure level

• Terme technique désignant l'intensité de la force exercée par un fluide ou un gaz sur une surface, souvent mesurée en décibels pour le son ou en pascals pour la pression physique.

A technical term referring to the magnitude of force per unit area exerted by a fluid or gas, often measured in decibels for sound or pascals for physical pressure.

1. Sound Pressure LevelC1formal

   A measure of the pressure of a sound wave relative to a reference value, usually expressed in decibels (dB).

   niveau de pression acoustique

   • The sound pressure level at the concert exceeded 100 dB.
   • Engineers measured the pressure level inside the acoustic chamber.
   • High pressure levels can cause hearing damage over time.

2. Atmospheric or Fluid Pressure LevelC1formal

   The amount of force exerted by a fluid (gas or liquid) per unit area, often measured in pascals or psi.

   pression de fluide

   • The pressure level in the hydraulic system must be monitored regularly.
   • Atmospheric pressure level decreases with altitude.
   • The pressure level inside the boiler reached critical limits.
