Objective and Subjective Voice Examination in Turkish Imams

Abstract

Imams are professional voice users and they are at high risk of developing voice problems. The aim of the present study was to investigate vocal acoustic parameters and voice handicap index (VHI) scores in Turkish imams and comparing these paramaters with a control group of male nonprofessional voice users. A total of 62 active working Turkish imams that never applied to our clinic with voice problems volunteered as subjects for the study and the control group consisted of 47 male nonprofessional voice users. Every participant completed a VHI questionnaire. A voice analysis was performed using computer program Dr.Speech Version 4 in an acoustically treated setting. Mean fundamental frequency, jitter, shimmer, harmonics to noise ratio values were recorded during the phonation and were analyzed. All imams were active working men aged 27-57 and the control group was comprised of male nonprofessional voice users of a similar age group. The measure of mean fundamental frequency, harmonics to noise ratio, jitter and shimmer rates were similar between two groups. In comparison of VHI between the groups no significant differences were found. Even though imams in the study group stated that they experienced voice problems in their professional lives, this did not cause any adverse changes in acoustic and subjective parameters (VHI) compared with control group.
