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…

In almost any given day, one will stumble upon sounds that are out of the ordinary, distinct enough to capture one's attention. Ordinary sounds in a home are represented by the white-noise-like background created by speaking, moving around, household appliances running, and so forth. The out of the ordinary is the sparkling sound of a knife blade…
