Abstract

Temporal integration of loudness of 1 kHz tones with 5 and 200 ms durations was assessed in four subjects using two loudness measurement procedures: categorical loudness scaling (CLS) and loudness matching. CLS provides a reliable and efficient procedure for collecting data on the temporal integration of loudness and previously reported nonmonotonic behavior observed at mid-sound pressure level levels is replicated with this procedure. Stimuli that are assigned to the same category are effectively matched in loudness, allowing the measurement of temporal integration with CLS without curve-fitting, interpolation, or assumptions concerning the form of the loudness growth function.

Mean temporal integration as a function of level for four individual subjects (1–4) estimated from CLS and loudness matching. The best polynomial fit to the data is shown for each individual track within a panel. The fit order was determined by visual inspection with the least order, which represented the data. The threshold for the 5 ms tone is also shown for all four subjects.
