Laryngovideostroboscopy is the method most frequently used in the assessment of voice disorders. However, the employment of quantitative methods, such as voice acoustic analysis, is essential for evaluating the effectiveness of prophylactic and therapeutic activities as well as for objective medical certification of larynx pathologies. The aim of this study was to examine voice acoustic parameters in female teachers with occupational voice diseases.
Acoustic analysis (IRIS software) was performed in 66 female teachers, including 35 teachers with occupational voice diseases and 31 with functional dysphonia.
The teachers with occupational voice diseases presented the lower average fundamental frequency (193 Hz) compared to the group with functional dysphonia (209 Hz) and to the normative value (236 Hz), whereas other acoustic parameters did not differ significantly in both groups.
Voice acoustic analysis, when applied separately from vocal loading, cannot be used as a testing method to verify the diagnosis of occupational voice disorders.
喉动态镜检查是评估嗓音障碍最常用的方法。然而，采用定量方法，如嗓音声学分析，对于评估预防和治疗活动的效果以及对喉部病变进行客观医学认证至关重要。本研究的目的是检查患有职业性嗓音疾病的女教师的嗓音声学参数。
对66名女教师进行声学分析（IRIS软件），其中包括35名患有职业性嗓音疾病的教师和31名功能性发声障碍教师。
与功能性发声障碍组（209Hz）和正常参考值（236Hz）相比，患有职业性嗓音疾病的教师平均基频较低（193Hz），而两组的其他声学参数无显著差异。
嗓音声学分析若独立于发声负荷应用，不能用作验证职业性嗓音障碍诊断的检测方法。
