摘要：Voice of vocal professionals is exposed to great temptations,i.e.there is a high probability of voice alterations.Smoking,allergies and respiratory infections greatly affect the voice,which can change its acoustic characteristics.In smokers,the vocal cords mass increases,resulting in changes in vocal fold vibratory cycle.Pathological changes of vocal folds deform the acoustic signal and affect voice production.As vocal professionals,teachers are much more affected by voice disorders than average speakers.The aim of this study was to examine the differences in acoustic parameters of voice between smoking and nonsmoking teachers,in a sample of vocal professionals.The sample consisted of 60 female subjects,aged from 25 to 59.For voice analysis we used Computer lab,model 4300,'Kay Elemetrics Corporation'.The statistical significance of differences in the values of acoustic parameters between smokers and nonsmokers was tested by ANOVA.Results showed that in the sample of female teachers,professional use of voice combined with the smoking habit can be linked to the changes in voice parameters.Comparing smokers and nonsmokers,average values of the parameters in short-term and long-term disturbances of frequency and amplitude proved to be significantly different.
