Abstract:The function of voice is multi dimensional. It is crucial for laryngologists, speech-language pathologists, musicians to obtain data regarding voice or to measure the voice quality. However, there is not a standard measurement for assessment of the voice function and voice quality. Perceptual assessments require experience in respect of voice assessment; therefore it is considered that acoustic voice analysis facilitates works of clinicians. 44 students from the Department of Music, who are successful and whose voice quality has been assessed by a jury of academicians in the Department of Music, have been taken as a fact group. 38 people, who have not been educated in the field of music, and have never dabbled in music, have been chosen as a control group. Voice of both groups have been recorded, and MDVP and VRP, within the scope of CSL programmed, have been utilized. For aerodynamic assessments, s/z ratio and MPT have been used. At the end of the study, statistical meaningful discrepancies have been determined in respect of PPQ, ShimdB, vAM, VTI, DSH, which are MDVP parameters, in the control group, when compared with the fact group. Meaningful contraction has been observed in MPT, s, s/z values in the control group. Meaningful discrepancy has been determined in respect of VRP parameters, Max Fo, Fo Range, Fo Range (St), Min dB SPL and Max dB SPL values. As a consequence, from our point of view, the fact that voice interval of the Department of Music is higher than the control group is requisite musically and plays a significant role in that they are preferable for the Department of Music. We can assume that the existence of large breathe capacity creates difference in control of sound intensity and tone. However, we advise that the regarding data are handled integrally; instead of usage of perceptual and objective tests in lieu of each other in assessment of sound.
