Masking
Psychophysical tuning function
(Zwicker, 1974)
•
Test tone with fixed frequency
•
Vary mid frequency of masking stimulus (narrow band)
•
Increase amplitude of mask until perception of test tone ceases
(From Goldstein, 1996)
Idea: neural unit for test frequency adressed;
Required strength of masking stimulus ~ threshold of the neural unit for masking stimulus
