What is the integration-time model?
the auditory system sums or integrates energy over time
in the integration-time model, if you have less ____ you need more _____
time; energy
in the integration-time model, once ________ exceeds some point, you don’t need extra _____
duration; energy
What is the multiple looks model?
sound is detected in short time windows and each sample is used to make a decision about the presence or absence of the sound
in the multiple-looks model, the ______ the sound the more “____” or the more _________ there is that a sound is ________
longer; looks; evidence; present
in the integration-time model, total energy = _____ X____
power X time
