Effect of Speaking over Background Noise on Acoustic Correlates of Normal Voice in Adult Females

The Impact of Extended Voice Use on the Acoustic Characteristics of Phonation After Training and Performance of Actors From the La MaMa Experimental Theater Club

“…Negative changes in voice quality were observed after high-pitched phonation, but no changes were noted resulting from a high-intensity level. In contrast, Gelfer et al, 7 Hill et al, 8 Stemple et al, 9 and Vilkman et al 10 documented an increase in habitual F o after prolonged reading tasks at a high vocal intensity. In the studies conducted by Stemple et al 9 and Vilkman et al, 10 subjects had difficulty matching their pretest levels of minimum pitch, which can be interpreted as an increase in phonatory threshold.…”
