Designing auditory displays requires understanding how different attributes of sound are processed. Operators must often listen to a particular stimulus dimension and make control actions contingent on the auditory information. Three experiments used a selective-listening paradigm to examine interactions between auditory dimensions. Participants were instructed to attend to either relative pitc...

The paper presents a new pitch generation model based on internal dependence of pitch contour. This model pays more attention to the impact of adjacent syllables’ pitch contours on the current one. A new definition of concatenation cost is presented to measure the naturalness of pitch contours between every two adjacent syllables. Based on this definition, the model concentrates on how to remov...

The present hydraulic variable-pitch mechanism of wind turbine uses three hydraulic cylinders to drive three crank and connecting rod mechanisms respectively; the blades are moved with the cranks. The hydraulic variable-pitch mechanism has complex structure, occupies a lot of space and its maintenance is trouble. In order to make up for the shortcomings of hydraulic cylinder variable-pitch syst...

We present original results and review literature from the past fifty years that address the role of primate auditory cortex in the following perceptual capacities: (1) the ability to perceive small differences between the pitches of two successive tones; (2) the ability to perceive the sign (i.e., direction) of the pitch difference [higher (+) vs. lower (-)]; and (3) the ability to abstract pi...

Congenital amusia is a lifelong disorder of music processing that has been ascribed to impaired pitch perception and memory. The present study tested a large group of amusics (n=17) and provided evidence that their pitch deficit affects pitch processing in speech to a lesser extent: Fine-grained pitch discrimination was better in spoken syllables than in acoustically matched tones. Unlike amusi...

A method for estimating the normalised pitch variation is described. While pitch tracking is a classical problem, in applications where the pitch magnitude is not required but only the change in pitch, all the main problems of pitch tracking can be avoided, such as octave jumps and intricate peak-finding heuristics. The presented approach is efficient, accurate and unbiased. It was developed fo...

Listeners without absolute (or "perfect") pitch have difficulty identifying or producing isolated musical pitches from memory. Instead, they process the relative pattern of pitches, which remains invariant across pitch transposition. Musically untrained non-absolute pitch possessors demonstrated absolute pitch memory for the telephone dial tone, a stimulus that is always heard at the same absol...

Previous studies on tones suggest that Mandarin listeners are more sensitive to pitch direction and slope while English listeners primarily attend to pitch height. In this study, just noticeable differences were established for pitch discrimination using a three-interval, forced-choice procedure with a two-down, one-up staircase design. A high rising and a high falling Mandarin tone were manipu...
