pressure level

• Termo técnico que designa a magnitude da força por unidade de área exercida por um fluido ou gás, frequentemente medida em decibéis para som ou em pascais para pressão física.

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).

   • 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.
