If a part of a file is selected then the signal is inserted instead the selected part, otherwise it is inserted to the current cursor position.
The Amplitude = -92 is equal to least noise signal, Amplitude = 0 is equal to most noise signal.

N - number of db.
Pn - Level of sound pressure in pascals.
P0 = 2*105 pascals.
