Background: Approximately one-third of the global work force requires good voice function in order to work efficiently. Voice Disorders are typically caused by disruptive structural changes in the vocal cords of the larynx (voice box). The changes can affect loudness, pitch, projection, and overall of quality thereby impairing an individual’s ability to communicate effectively. Teachers have previously been identified as a group of voice professionals for whom the risk of voice disorders is high. Moreover, some research suggests that voice quality of a teacher can have a significant impact on the ability for students to learn. This research will compare voice risks based on classroom size, vocal load during the day, use of amplification, and design of the classroom, as well as factors related to voice use outside of teaching activities.
Objectives: The aim of this research is to identify and compare risk factors for voice disorders amongst teachers in an urban environment
