目的:验证芬兰管的半闭塞声带运动对聋哑音乐家的声音质量的听觉感知和声学效果。
方法:使用芬兰试管进行为期7天的方案,并指导其每天两次进行家庭复制。一名46岁的男性患有严重的双侧感音神经性听力损失,音乐家和作曲家参加。在协议应用之前和之后都进行了音调测听,鼻纤维喉镜检查,使用Praat进行声学分析,并使用巴西葡萄牙语的语音配置文件分析方案对语音进行听觉感知评估。
结果:干预后的听觉-知觉分析确定了嘴唇传播偏差的减少,广泛的阴唇范围,凸起的舌头身体,咽部扩张,鼻共振,喉高度,喉和声带张力和不规则,螺距,语速,更好的呼吸支持.最大发声时间减少,可能是因为消除了突然的声音攻击和紧张,发音偏差,改善发声和不使用呼气储备空气。基本频率降低了,第一个,第二,第三,第四个共振峰变得更高。抖动增加,微光减少了。
结论:使用芬兰管可能促进了聋哑音乐家的发声感觉,通过增强声道的触觉-动觉感知,并带来更大的源-滤波器相互作用。
OBJECTIVE: To verify the auditory-perceptual and acoustic effects of the semioccluded vocal tract exercise with Finnish tube on the vocal quality of a deaf musician.
METHODS: A seven-day protocol with Finnish tube was performed with guidance for its home replication twice a day. A 46-years-old man with profound bilateral sensorineural hearing loss, musician and composer participated. Before and after the application of the protocol had undergone tonal audiometry, nasofibrolaryngoscopy, acoustic analysis with Praat and auditory-perceptual evaluation of the voice with Voice Profile Analysis Scheme for Brazilian Portuguese.
RESULTS: The postintervention auditory-perceptual analysis identified reduction of the deviation in lip spreading, extensive labial range, raised tongue body, pharyngeal expansion, nasal resonance, larynx height, larynx and vocal tract tension and irregularity, pitch, speech rate, and a better respiratory support. The maximum phonation time reduced, probably because of elimination of the abrupt vocal attack and tension, articulatory deviations, improvement in voicing and the absence of the use of expiratory reserve air. The fundamental frequency became lower, and the first, second, third, and fourth formants became higher. The jitter increased, and the shimmer reduced.
CONCLUSIONS: The use of the Finnish tube might have facilitated the voicing sensations in the deaf musician, by enhancing the tactile-kinesthetic perception of the vocal tract and brought a greater source-filter interaction.
