Aerodynamic measures of maximum phonation duration and S/Z ratio in professional voice users

Author(s): Meghana S, Dr. Reeny Roy
Abstract: Earlier literature have a dearth of comparative studies on a group of professional voice users. The aim of the study is to investigate the pre and post aerodynamics across professional voice users in the age range 25-45 years. This study comprised of total 100 subjects without any voice complaint. The subjects were divided into five professional voice users (Group I-Teachers, Group II- Singers, Group III-Speech language pathologist, Group IV- Lawyers and Group V Call-centers). Each group was further divide into 10 males and 10 females. All subjects were measured pre and post aerodynamic measures (MPD & s/z ratio) manually. The Group V Callcentres showed high negative impact of MPD and s/z ratio in the post recording compared to pre-recording. Across gender comparison, females showed highest negative impact compared to males. This study concluded that it is very essential and important to assess the aerodynamics characteristics of voice in all professional voice users. This will helpful in the assessment and management protocol for different professional voice users.
