ABSTRACT
The acoustic tests of voice were carried out on 46 children with noduli vocales before the treatment and after its completion. Acoustic parameters of voice were compared with the control group of children without voice pathology. The results of the investigation were analysed acoustically. It has been proved that jitter, shimmer, Fo tremor and HNR values significantly differentiate the children with noduli vocales from the children without pathological changes in the larynx. These parameters during treatment tend to approach normal values. Therefore, the acoustic analysis of voice may be used in treatment monitoring.

The study concerns 11 patients with gastroesophageal disease confirmed by pH-metric examination of esophagus. The clinical assessment included lupolaryngoscopy, stroboscopy and acoustic analysis of voice. Basing on the tests there were confirmed inflammatory lesions at the posterior part of larynx (laryngitis posterior) as well as pathological changes of voice acoustic tests.

Porophonia pubertum is the change of voice following activation of gonads in puberty. The present paper shows disorders of porophonia pubertum in 3 boys. The objective of the paper was to explain the pathogenesis of these disorders. Basing on clinical and genetic tests, a non-physiological, high position of spoken voice typical for the prolonged porophonia pubertum was proved. The genetic test confirmed the male sex. However, hormonic tests proved a significantly increased level of estradiol. We suppose that excessively increased estradiol level in blood serum caused the porophonia pubertum disorders in our patients.
