Purpose: Good verbal signals and low background noise are key factors for all children to maximize understanding of what is being taught. Classroom shape, surroundings, and even furnishings change how the environment "sounds" and how speech is "heard" in the classroom. Classroom acoustics is perhaps one of the most important,…

Purpose: The purpose of this project is to assess the acoustical conditions in which optimal intelligibility and low listening difficulty can be achieved in real classrooms for elementary students, taking into consideration the effects of dysphonic voice and typical classroom noise. Method: Speech intelligibility tests were performed in six…

The interest in achieving improved acoustical conditions in classrooms has increased in the last years. Some experiments on acoustics phenomena using smartphone applications appear in the recent bibliography. In this paper, we present a proposal for active learning about room acoustics for high school and undergraduate students. Students work on…
