ABSTRACT
Purpose
The purpose of this study is to verify the difference in fundamental frequency, intensity and vocal dose measurements between male and female cisgender people, in same voice demand situations.
Methods
This is a cross-sectional observational case study. Group 1 participated with five male people, aged between 21 and 24 years old and Group 2 with five female people, aged between 22 and 25 years old, both without vocal complaints, students of the Speech-language pathology course. The individuals were paired by vocal demand, and all were enrolled in the same activists of the undergraduate course. All participants defined themselves as cisgender, that is, they identified themselves with the gender designated at birth. The data was carried out at the same time, for a period of 10 hours, while the participants carried out their daily activities for that period. For data collection, two dosimeters of VoxLogⓇ, were used. Student's t test was used to compare measures between groups. The 95% confidence level was considered.
Results
It was observed that women have higher values of fundamental frequency (p=0,001), percentage of phonation (p=0,037), cyclic dose (p=0,002) and distance dose (p=0,008). The voice intensity of both groups was similar in the period evaluated.
Conclusion
cisgender women have higher values of fundamental frequency, percentage of phonation, cyclic dose and distance dose than cisgender men. Assessing the vocal dose between genders is important for a better understanding of the etiological factors of behavioral dysphonia and to define a more personalized vocal rehabilitation.
