Modelling of Auditory Masked Thresholds in Humans
In order to be able to predict the probability of detection of an acoustic sound in noise, it is necessary to be able to define the masked threshold of that noise along with the level of the sound required to be detected. The phenomenon of obscuring the detection of one sound by another is defined as auditory masking and is one of the more classical problems of the detecting and classifying of signals in noise. Auditory masking is particularly important when threshold listening is involved, that is listening for low level signals in conditions of high noise, and from a military viewpoint it is of great importance when attempting to complete auditory monitoring tasks of sonar signals or electronic warfare returns. Masking, however, is not solely a military problem, but is important wherever a human is required to listen, detect and classify.
