Temporal resolution and temporal masking properties of transient stimuli: Data and an auditory model

摘要: Temporal resolution is often measured using the detection of temporal gaps or signals in embedded long-duration stimuli. In this study, psychoacoustical paradigms are developed for measuring encoding transient The stimuli consisted very short pips which, two experiments, contained a steady state portion. carrier was high-pass filtered, dynamically compressed noise, refreshed every stimulus presentation. first experiment shows that, with these stimuli, gap thresholds about same as obtained previous investigations. Experiments II and III show temporal-separation duration-discrimination better than gap-detection thresholds. Experiment IV investigates significance residual spectral cues listeners’ performance. V, separation were function signal-pip sensation level (SL) both forward- backward-masking conditions. strong asymmetry good independent SL conditions increasing decreasing forward-masking A model auditory periphery used to simulate quantitatively. By varying parameters like auditory-filter width transduction time constants, provides some insight into how peripheral system may cope processing tasks thus represents more physiology-related complement current models processing.
