The Journal of the Acoustical Society of America, 1952
A new determination was made of the way in which differential sensitivity for frequency varies both with loudness level (up to 30 phons) mud with frequency (60–4000 cps). The effect of loudness level is independent of frequency, but sensitivity (in terms of cycles discriminable) improves continuously as frequency decreases.

The Journal of the Acoustical Society of America, 1991
Dichotic Huggins pitch was produced by generating broadband noise stimuli with narrow sections of the noise (bandwidths of 2, 4, 8, 16, 32, 64, and 128 Hz) interaurally phase shifted (by 90°, 135°, or 180°). The center frequencies of the narrow dichotic bands to which the interaural phase shifts were added were varied to change the value of the Huggins

Context effects in pitch discrimination
Journal of the Acoustical Society of America, 2016The perceived direction of pitch change between a pair of tones depends on their frequencies, but may also depend on the prior history of stimulation or behavioral response. To quantify the contribution of such context effects, we used a recently developed pitch change discrimination paradigm in which subjects judge the direction of change after each ...

Measurement of Pitch Discrimination
Journal of Research in Music Education, 1973Two attitudes are detectable in the research of psychologists interested in the measurement of musical abilities. Some researchers have accepted the dictum originally expressed by Seashore that Inusicality comprises a number of component abilities, each of which is capable of individual measurement.l Investigations based on this viewpoint have taken ...

Pitch Discrimination of Complex Sounds
The Journal of the Acoustical Society of America, 1959Apparently the pitch limen for a single, high-frequency sinusoid can be smaller in the presence of a nearby constant frequency component than in isolation. The explanation lies in the time-envelope properties of the two-frequency complex. This reduced DL is considerably larger in cps but smaller in percentage than the DL for a sinusoid of the envelope ...

Discrimination of Missing Pitch Pulses
The Journal of the Acoustical Society of America, 1962The object of this experiment was to determine the discriminability of missing pitch pulses in synthesized vowel-like sounds. Pitch pulses were derived from samples of real speech. Individual pitch pulses were removed from certain parts of these pulse trains. A fixed vowel POVO-type synthesizer was then excited by these pulse trains, and listeners were

Simultaneous Two-Tone Pitch Discrimination
The Journal of the Acoustical Society of America, 1957The frequency separation between two simultaneously sounding tones necessary to give perception of two pitches has been investigated. Frequency levels of 200, 1000, 4000, 6000, and 10 000 cps were used. For the two-ear condition (where one tone was led to one ear, the other tone to the other ear), no striking differences were found between results at ...

Pitch Discrimination of Jittered Pulse Trains
The Journal of the Acoustical Society of America, 1965Listeners are presented with pulse-train stimulus pairs and asked to judge whether they can hear a difference between them. The interval between pulses is a random variable, identically and independently distributed for each stimulus of a pair. Two distributions are observed: one, nominally Gaussian, and the other, nominally the distribution of the ...

Fetal discrimination of low-pitched musical notes
Developmental Psychobiology, 2000Cardiac responses of 36- to 39-week-old (GA) fetuses were tested with a no-delay pulsed stimulation paradigm while exhibiting a low heart rate (HR) variability (the HR pattern recorded when fetuses are in the 1f behavioral state). We examined whether fetuses could discriminate between two low-pitched piano notes, D4 (F(0) = 292 Hz/292-1800 Hz) and C5 ...

Vocal pitch discrimination in the motor system
Brain and Language, 2011Speech production can be broadly separated into two distinct components: Phonation and Articulation. These two aspects require the efficient control of several phono-articulatory effectors. Speech is indeed generated by the vibration of the vocal-folds in the larynx (F0) followed by ''filtering" by articulators, to select certain resonant frequencies ...
