'Listener fatigue' occurs when the
ear tunes out unwanted
noises and focuses on the wanted ones. When listening to music for example, the
speakers may give off an unwanted hissing noise that the person has to focus out, causing "Listener Fatigue".
This is an extension of the
quantifiable psychological perception of
sound, adding time-variance effects.
