Launched in 2014, our series of articles, Physical Processes in Nature [1-6],
aims to provide tangible, concrete help to educators in integrated science education. In this series, we deal with phenomena affecting the sciences of physics, biology and geography and their explanations, thus helping the teaching work of a unified science approach for pedagogical colleagues. In the first article of the series, we summarized
the physical characteristics of soil physics , the second the physical and chemical characteristics of water , the third the oceans and seas , the fourth the lakes ,
the fifth the rivers , and the sixth the depth characteristics of the deep waters . In
this article, we deal with sound as a physical phenomenon, covering its physiological
effects, noise pollution, and its reduction potential.
