PURPOSE: to determine the modal sound pressure level (SPL) and maximum phonation time (MPT) /a/ adult woman without vocal complaints or laryngeals disorders, before, immediately after and five minutes after the execution of the technique of Finger kazoo (FK). METHOD: collection of the MPT /a/, measure of fundamental frequency (f0) and its standard deviation, and measuring the modal SPL, 32 woman between 18 and 40 years of age without vocal complaints or laryngeal disorder before (M1), after three sets of 15 repetitions of FK (M2), and five minutes after silence (M3). Spearman, Tukey and Friedman tests. RESULTS: increase of modal NPS M2 (significance), and M3, increased of MPT /a/ in M2 and M3. CONCLUSION: in the studied group of adult woman without vocal complains or laryngeal disorders, there was a higher in the modal NPS immediately after three sets of 15 repetitions of the FK technique, showing that the technique can influence the sound pressure the loudness and vocal projection.
