摘要

The purpose of this research was to investigate the ability of deaf children to discriminate pitch of complex tones. The research was designed to study the effects of age and school musical experiences on pitch discrimination and to identify possible relationships between pitch discrimination and other variables, including hearing levels, academic achievement, and home music background.;A pitch discrimination test was designed to measure the difference limen for frequency (DLF) at 250 and 500 Hz. Subjects (ages 6 to 9 and 11 to 12) were selected from two residential schools for the deaf; one school included music classes in the curriculum. Information regarding prior musical experiences was elicited from subjects' parents and classroom teachers via written questionnaires. Audiometric data and achievement levels were obtained from school records. Programs in SPSSX were used to analyze data.;Subjects demonstrated great variability in DLF sizes. The DLFs on the 250 Hz subtest ranged from 17.5 Hz to greater than 103 Hz; the median DLF was 39.9 Hz. On the 500 Hz subtest, DLFs ranged from 26 Hz to greater than 205 Hz; the median DLF was 86.2. The results of two-way ANOVA did not reveal any statistically significant differences between subjects when grouped by age and school. There were moderate to high positive correlations between DLF and hearing levels among the younger subjects; among older subjects, there was little or no correlation between DLF and hearing levels. A stepwise multiple regression identified the hearing level at 250 Hz to be the best predictor of DLF at 250 Hz and 500 Hz.;Results suggest that deaf children may benefit from appropriate pitch-related activities. Implications for music educators include using music in lower registers, discriminating large changes of pitch, and allowing for language deficiencies through the use of concrete examples of pitch concepts and a variety of communication modes.
