Masking a low-frequency sinewave
-The first tone you'll hear is a 100 Hz signal.
you should set your speakers so that the tone is just audible.
Otherwise the noise signal will be too loud, and the listener will loose
nerves!!!
-Signal (starting from 60 Hz) is masked with noise.
The frequency of the signal is then increased in 10 steps of 10 Hz until
150 Hz.

sound (.wav). See also the Matlab M-file
M-file (.m).
Masking high-frequency sinewaves
-In the end, after ten steps of low frequencies, are five examples of high
frequencies masked with same noise and starting from 15 000 Hz, climbing
up to 19 000 Hz in five steps of 1 000 Hz
