Psychoacoustics: Raise listening threshold

096/107

The noise from the plane raises the listening threshold and the speech moves into the inaudible range.


(*) hörbar = audible   (*) unhörbar = inaudible  
(*) Sprache = voice  (*) Flugzeug = aircraft

The stronger the effect of the masking,
the smaller the distance between the frequencies.

Strong low tones mask higher, weak tones
 stronger than vice versa.
