Level discrimination of sinusoids as a function of duration and level for fixed-level, roving-level, and across-frequency conditions.
The ability of listeners to detect level differences between two sinusoidal stimuli in a two-interval forced-choice procedure was measured as a function of duration and level in three conditions: (1) the pedestal was fixed in level and the stimuli in the two intervals had the same frequency of either 1 or 2 kHz (fixed-level condition); (2) the pedestal was roved in level over a 20-dB range from...
متن کاملA general equation describing frequency discrimination as a function of frequency and sensation level.
Frequency-discrimination thresholds, for a wide range of stimulus frequencies and stimulus levels, were obtained from three normal-hearing listeners. Linear regression analyses of the present data, and of data from two previous studies, indicate that an SL-1 transformation of stimulus level and a square root F transformation of stimulus frequency yield linear dimensions that allow accurate pred...
متن کاملBrightness Discrimination as a Function of the Duration of the Increment in Intensity
1. This investigation has been concerned with an analysis of brightness discrimination as it is influenced by the duration of DeltaI. The durations used extend from 0.002 second to 0.5 second. 2. DeltaI/I values at constant intensity are highest for the shortest duration and decrease with an increase in duration up to the limits of a critical exposure time. At durations longer than the critical...
متن کاملDetection and discrimination of frequency glides as a function of direction, duration, frequency span, and center frequency.
The study investigated the ability to detect and discriminate frequency glides under a variety of experimental conditions. The subjects distinguished between a comparison signal that either was level in frequency or was swept across a fixed frequency span, and a target signal that changed more in frequency than the comparison signal. Tone durations were 50 and 400 ms. Nominal center frequencies...
متن کاملIntensity discrimination as a function of stimulus level with electric stimulation.
Difference limens (DLs) for changes in electric current were measured from multiple electrodes in each of eight cochlear-implanted subjects. Stimuli were 200-microseconds/phase biphasic pulse trains delivered at 125 Hz in 300-ms bursts. DLs were measured with an adaptive three-alternative forced-choice procedure. Fixed-level psychometric functions were also obtained in four subjects to validate...
