Abstract
Temporal integration of acoustic stimuli in man has been the subject of many investigations. The findings differ considerably; one reason might be lack of control of the acoustic input. In view of recent investigations by Brahe Pedersen and others with well-controlled stimuli, the traditional concept of perfect integration of acoustic energy may be questioned and there is an obvious need for more complex models to describe the results. This does also apply to the problem of expressing the data for clinical and scientific purposes. Very little is known of the underlying neurophysiological effects. The idea of comparing the visual and the auditory systems for this purpose is advanced.
