1474450693 THE EFFECT OF SINGING TRAINING ON ACOUSTIC PARAMETERS OF VOICE

The aim of the present study is to analyze the impact of singing training on the acoustic properties of students’ voices. The participants of the stuy were 20 students between 19 and 32 without absenteeism ranging from the 1st to the 4th grade. The voices of 12 female and 8 male students, enrolled at Selcuk University Dilek Sabancı State Conservatory Opera Main-department, Sub-department of Vocal Arts were recorded throughout 2014-2015 academic year using Shure Sm 48 model microphone in order to determine their acoustic properties using CSL (Computerized Speech Laboratory) 4500 to the computer with Kay Elemetrics MDVP (Multi Dimensional Voice Program). In order to determine changes in the acoustic parameters and evaluate the effectiveness of the singing training given, a single sample -pre and post-test research design was used. Hence, among the acoustic properties, F0, (Fundamental Frequency) F1, F2, F3, F4, F5, formant frequencies, jitter (%), shimmer (%), NHR (Ratio of harmonic noise) parameters were evaluated. The statistical analyses made for the comparison of MDVP parameters before and after the vocal training revealed no statistically significant difference in the students’ F0, Jitter, Shimmer, NHR, F1, F2, F3, and F4 acoustic parameters. However, the F5 formant value revealed statistically significant differences in all the students and a statistically significant difference was seen in the F0 parameter and F5 formant values of female students. Fundamental frequency (F0) is an important parameter changing throughout the singing training process among the female students’ acoustic characteristics. The increase in the F5 formant values of female students and the acoustic properties of all students within normal ranges could be considered as an indicator of the positive impact of the singing training received.
