The aim of the study was to assess the acoustic and capacity analysis of singing voice using DiagnoScope Specialist software.
The study was conducted in 131 adult subjects, including 74 women and 46 men aged 21-51, divided into 3 groups: I - 40 subjects (treatment group) - professional vocalists, II - 40 subjects (treatment group) - semiprofessional vocalists, III - 40 subjects (control group) - students of The Military Medical Faculty at the Medical University of Lodz - nonsingers. The research methodology included: primary medical history, physical examination (otolaryngological), videolaryngoscopic examination, the GRBAS scale for subjective voice evaluation, diagnostic voice acoustic and capacity analysis using DiagnoScope Specialist software, survey on lifestyle patterns which may affect voice quality. R esults: Average value of the fundamental frequency F0 was the highest in professional vocalists group; it was 316.46 Hz in women and 165.09 Hz in men. In semiprofessional vocalists group it was accordingly 260.50 Hz and 149.26 Hz, in nonsingers group it was accordingly 261.23 Hz and 159.27 Hz. The mean value of Jitter parameter in professional vocalists group was 0.30% in women and 0.54% in men, in semiprofessional vocalists group it was accordingly 0.31% and 0.57%, in nonsingers group it was 0.31% and 0.56%. The mean value of Shimmer parameter in professional vocalists group was 3.27% in women and 3.75% in men, in semiprofessional vocalists group it was accordingly 3.46% and 3.77%, in nonsingers group it was 4.33% and 4.39%. The mean value of the NHR index in professional vocalists group was 3.28% in women and 6.00% in men, in semiprofessional vocalists group it was accordingly 3.23% and 6.72%, in nonsingers group it was 3.89% and 6.13%.
Values of the parameters which measure the character of the voice, relative period-to-period fundamental frequency perturbations, relative period-to-period amplitude perturbation and level of buzzing together with other methods have diagnostic and predictive value in early detection of voice disorders. Capacity analysis in singing voice showed very low values of the following parameters: phonation time, true phonation time, no phonation coefficient, voice efficiency coefficient and voice capacity.
本研究旨在使用DiagnoScope Specialist软件对歌唱嗓音进行声学和容量分析。
该研究对131名成年受试者进行，其中包括74名女性和46名年龄在21至51岁之间的男性，分为3组：I组 - 40名受试者（治疗组） - 专业歌手；II组 - 40名受试者（治疗组） - 半专业歌手；III组 - 40名受试者（对照组） - 罗兹医科大学军事医学院的学生 - 非歌手。研究方法包括：初步病史、体格检查（耳鼻喉科）、视频喉镜检查、用于主观嗓音评估的GRBAS量表、使用DiagnoScope Specialist软件进行嗓音声学和容量诊断分析、关于可能影响嗓音质量的生活方式模式的调查。
专业歌手组的基频F0平均值最高；女性为316.46Hz，男性为165.09Hz。半专业歌手组相应为260.50Hz和149.26Hz，非歌手组相应为261.23Hz和159.27Hz。专业歌手组的抖动参数平均值女性为0.30%，男性为0.54%；半专业歌手组相应为0.31%和0.57%，非歌手组为0.31%和0.56%。专业歌手组的闪烁参数平均值女性为3.27%，男性为3.75%；半专业歌手组相应为3.46%和3.77%，非歌手组为4.33%和4.39%。专业歌手组的NHR指数平均值女性为3.28%，男性为6.00%；半专业歌手组相应为3.23%和6.72%，非歌手组为3.89%和6.13%。
测量嗓音特征、基频逐周期相对扰动、逐周期幅度相对扰动以及嗡嗡声水平的参数值与其他方法一起在嗓音障碍的早期检测中具有诊断和预测价值。歌唱嗓音的容量分析显示以下参数值非常低：发声时间、实际发声时间、无声系数、嗓音效率系数和嗓音容量。
