Difference in Voice Problems and Noise Reports Between Teachers of Public and Private Schools in Upper Egypt

Objective: This study aimed to assess teachers' voice symptoms and noise in schools in Upper Egypt and to study possible differences between teachers in public and private schools. Study Design: A cross-sectional analysis via questionnaire was carried out. Methods: Four schools were chosen randomly to represent primary and preparatory schools as well as public and private ones. In these schools, a total of 140 teachers participated in the study. They answered a questionnaire on vocal and throat symptoms and their effects on working and social activities, as well as levels and effects of experienced noise. Results: Of all teachers, 47.9% reported moderate or severe dysphonia within the last 6 months, and 21.4% reported daily dysphonia. All teachers reported frequent feelings of being in noise, with 82.2% feeling it sometimes or always during the working day, resulting in a need to raise their voice. Teachers in public schools experienced more noise from nearby classes. Conclusion: The working conditions and vocal health of teachers in Upper Egypt, especially in public schools, are alarming.
