The Stability

Absolute pitch (AP) is the ability to identify or produce a given pitch without a reference. This study examines the stability of pitch labeling accuracy in a broad sample of AP possessors when natural complex tones are compared to modified sound structures (slightly out-of-tune pitches, sounds with missing fundamentals, and pure tones). A passive listening test with single tones was developed (Tallinn Test of Absolute Pitch, TTAP), with 150 items selected, representing 60 synthetic instrumental tones (violin, clarinet, and trumpet) in different octave ranges and dynamics, and 90 electronically modified sounds, each presented in three different octave ranges. Additional information was collected, regarding handedness, start of instrumental instruction, educational status, occurrence of AP in the family, and associations with processing pitch recognition. Results showed a clear decrease of pitch recognition accuracy between natural complex sounds and pure sine tones. A significant main effect on TTAP scores was found for early starts of instrumental instruction. The findings are discussed in the context of the nature-nurture debate (genetic vs environmental factors), as well as the implications of genetic and memory aspects of pitch recognition.

Stimulus Degradation

A binaural recording of traffic sounds that reached an artificial head oriented in five different positions was presented to five subjects, each of whom responded under four different criteria. The results showed that it is possible to examine the ability of listeners to localize sound while listening through earphones and that the criterion adopted by an individual listener is independent of his performance. For the experimental conditions used, the Type II ROC curve generated by manipulating criterion behavior was linear and consistent with a guessing model. Further experiments involving different degrees of stimulus degradation suggested a partial explanation for this finding and illustrated the various types of monaural and binaural cues used by normal and hearing-impaired listeners to localize complex sounds.
