Abstract
School teachers are known to have an elevated risk of voice problems due to the vocal demands in their work environments. Forty-five participants (20 females, 25 males, 7 elementary school teachers, and 38 college-age adults) performed a short vocal task in two different rooms: a variable-acoustics room and an anechoic chamber. The subjects were taken back and forth between the two rooms using a deception protocol. Each time they entered the variable-acoustics room, the acoustical characteristics (two background noise conditions and two reverberation conditions) had been changed without a visual appearance of change. Analysis was conducted on recorded second and third sentences of the first paragraph of the Rainbow Passage. Results revealed that differences in response to reverberation was gender specific. Additionally, school teachers seemed to be more susceptible to the noise condition.
