overall SPL

Definitions

Electronics

  • The total SPL taking into account multiple sources of sound energy. For example, the SPL produced by a speaker with multiple drivers, or that of a specific location within a city where cars, trucks, buses, trains, construction sites, factories, people, and many other sources contribute the overall noise present.
  • The SPL for a given interval of frequencies which encompasses other intervals. For instance, the SPL produced by a speaker system, as opposed to that produced by the subwoofer only.
