title: Daily rhythm of temporal resolution in the auditory system.
abstract: Over a period of 24 hours, fusion thresholds (click durations 100 micros) were assessed in 7 subjects. Over the same period, order thresholds (click duration of 1 ms) were measured in 10 subjects (12 independent sessions). Auditory fusion thresholds showed a diurnal rhythm with a maximum performance (shortest intervals) around midnight. In contrast, order thresholds appear to be independent on the time of day. Sex specific differences in threshold levels were only observed in order thresholds but not in fusion thresholds.
