| Summary: | 碩士 === 國立臺北護理健康大學 === 聽語障礙科學研究所 === 102 === The purpose of this study was to establish and compare acoustic and aerodynamic parameters of Taiwanese female within adult age. Voice samples were recorded from 83 healthy women. Participants were divided into 6 age groups. Acoustic parameters included speaking fundamental frequency (SFF), speaking intensity, jitter, shimmer, and noise-to-harmonic ratio. Aerodynamic parameters included vital capacity (VC), maximum phonation time (MPT), mean air flow rate, oral pressure, and phonation threshold pressure (PTP). one-way analysis of variance and Kruskal-Wallis test were used to analyze the differences of all parameters between 6 groups, and simple linear regression was used to analyze the relationship between age and each parameter. Results of acoustic measurements revealed that SFF, SFF SD, lowest SFF, speaking intensity, speaking intensity SD, and highest speaking intensity had significant difference between 6 groups. SFF and shimmer decreased with age; SFF SD, speaking intensity, speaking intensity SD, highest speaking intensity, and speaking intensity range increased with age. Results of aerodynamic measurements revealed that MPT, VC, oral pressure, and PTP had significant difference between 6 groups. MPT and VC decreased with age. Results were discussed with age-related changes of female neuromuscular, respiratory, and laryngeal systems, hormone production, and hearing ability. The results could provide references for clinical speech-language pathologists to execute voice assessment and therapy for different age groups of women.
