Phonation is a sensitive indicator of palatopharyngeal obstruction and its physiological force. The aim of the study was to evaluate the influence of nasality on the voice quality. The study was carried out on 125 patients divided into three subgroups. The first was created of the patients treated due to allergic rhinitis, the second was composed of patients with adenoids, the third one consisted of patients with cleft palate. The following acoustic parameters were assessed: Fo, Jitter, Shimmer, Fo-tremor, NNE, HNR, SNR. The results of the experimental and control groups were analysed statistically with Student's t-test. The performed acoustic tests of voice confirmed statistically significant elevation of Fo, HNR and SNR frequency in the studied group as compared with the control group.
发声是腭咽阻塞及其生理力量的敏感指标。本研究的目的是评估鼻音对嗓音质量的影响。该研究对125名患者进行，分为三个亚组。第一组由因过敏性鼻炎接受治疗的患者组成，第二组由腺样体患者组成，第三组由腭裂患者组成。评估了以下声学参数：基频（Fo）、抖动、闪烁、基频震颤、噪声能量比（NNE）、谐噪比（HNR）、信噪比（SNR）。实验组和对照组的结果采用学生t检验进行统计学分析。所进行的嗓音声学测试证实，与对照组相比，研究组的基频、谐噪比和信噪比频率有统计学意义的升高。
