월경 주기가 여성의 목소리에 미치는 영향

Change of Voice during Menstrual Cycle

Baekgroud and Objectives: The study was purposed to evaluate the relationship between the voice change and the menstrual cycle by measuring the variation of subjective and objective parameters. Materials and Methods: Prospective study of 13 healthy women during 2 mentrual cycles. Their voices were recorded at follicular phase and then luteal phase of the menstrual cycle. We used both single vowel /a/ and sentences for evaluate acoustic parameters. Aerodynamic parameters were also evaluated. Voice handicap index (VHI), and the presence of premenstrual syndromes (PMS) were checked at each period. We used Wilcoxon's signed rank test to compare the parameters of two periods. Results: VHI were 5.1 at both periods (p=0.146) and 92.3% of women were diagnosable with PMS. There were no significant differences in acoustic parameters and aerodynamic parameters between the two periods. Conclusion: This study shows that not only the subjective but also the objective changes of the voice parameters did not exist during the menstrual cycle in women.
