Abstract
The detection of a silent interval or gap provides important insight into temporal processing by the auditory system. Previous research has uncovered a multitude of empirical findings leaving the mechanism of gap detection poorly understood and key issues unresolved. Here, we expand the findings by measuring psychometric functions for a number of conditions including both across-frequency and across-intensity gap detection as a first study of its kind. A model is presented which not only accounts for our findings in a quantitative manner, but also helps frame the body of work on auditory gap research. The model is based on the peripheral response and postulates that the identification of gap requires the detection of activity associated with silence.

Notes
One might ask why detection is not carried out in the manner of a single sample t test: an estimate of the sample mean is obtained during the marker, and a single comparison is made against the ISI obtained during silence. However, such a test is only possible if the observer already knows when is marker and when is silence, and thus this strategy is not suitable in the present case. Our model, on the other hand, requires the listener to know the values of \(\mu _m\) and \(s_m\). We simply assume that these parameters are learned through the practice trials conducted prior to the start of the experiment.
