标题： Sound and Noise: Proposal for an Interdisciplinary Learning Path

摘要： 从声波的表征开始，提出一个学习路径，展示人类如何发出语言中的清晰声音，介绍心理声学，即声音如何与耳朵相互作用，并被转换为电信号传输到大脑。作为噪声被感知的内容被呈现，并且该概念被扩展到物理测量。跨学科的教学过程专注于通过在学校内外进行的活动进行主动学习，使用开源软件来记录声音并分析频谱成分。 显示英文摘要

摘要： A learning path is proposed starting from the characterization of a sound wave, showing how human beings emit articulate sounds in the language, introducing psychoacoustics, i.e. how the sound interacts with ears and it is transduced into an electrical signal for transmission to the brain. What is perceived as noise is presented and the concept is extended to physical measurements. The interdisciplinary teaching process is focused on active learning through activities at school and outside performed with an open source software which allows to record sounds and analyze spectral components.
