Abstract 

The main aim of this study was to describe the changes in acoustic analysis in diagnosing voice disorders in children. The secondary goal was the attempt at differentiation of organic and functional disorders by means of acoustic analysis. The study included 112 children in treated due to laryngeal papilloma, gastro–esophageal reflux, atopic disease and noduli vocales. The following values have been determined: basic frequency Fo, jitter, shimmer, Fo tremor and the harmonics to noise ratio (HNR). The study results confirmed that the HNR value was the most sensitive indicator of changes in the voice organ.
