Adapted air flow and phonic coefficients of future voice professionals

Purpose to verify and correlate adapted air flow (AAF), simple phonic coefficient (SPC) and composed phonic coefficient (CPC) in young adult future voice professionals of both genders which have normal voice as well as verifying frequency of sexes. Methods 62 subjects between 18 and 35 years old (12 men, mean 24,25 years old and 50 women, mean 21,42 years old); vocal evaluation by means of the RASATI scale with Kappa reliability coefficient; collecting of the maximum phonation time (MPT) of /a,i,u,s,z/, counting of numbers, vital capacity and AAF; calculation of the SPC and CPC; Spearmann test for correlations between variables and binomial test for the proportions of normal, diminished and increased values. Results majority significantly feminine presented SPC and CPC normal, and FAA normal and incresead when compared to the diminished values. Majority significantly masculine presented SPC normal and increased, when compared to the diminished values; normal CPC and no statistically meaningful difference on AAF. There was moderate positive correlation between SPC and CPC for both genders. Conclusion majority significantly of the studied future voice professionals presented SPC and CPC normal with moderate positive correlation between these measurements. Majority significantly feminine obtained normal results AAF when compared increased values and AAF did not have correlation with SPC and CPC. Majority significantly of the group of future voice professionals was women.
