SUMMARY OR ABSTRACT
Text of Note
This study addresses the high degree of voice use of a Muslim imam who leads prayer during the month of Ramadan when Muslims fast. Acoustics, aerodynamic, and endoscopic descriptions were obtained before and after Ramadan for the adult male participant. In addition, the imam wore an ambulatory voice monitor for 12 days during Ramadan. After Ramadan, it was found that the imam experienced changes in aerodynamic measurements (airflow, subglottal pressure estimates, and sound pressure level/subglottal ratio), had less pitch range, and developed mild fibrovascular changes on his vocal folds. Average sound pressure level, fundamental frequency, and all vocal dose measurements were significantly higher during prayer than periods before prayer. The imam's phonation time during prayers was increased compared to other professional voice users during working hours. The results provide a framework for future studies to explore the voice use measurements of a large sample of imams for whom different vocal loading experiences may vary.
