It manifests itself in the form of a hum, rumble and pulsing, often felt as a sensation more than an audible sound. Starting in 2011, residents of Windsor, Ontario, Canada started reporting intermittent low frequency sound, widely referred to as the Hum(and dubbed the Windsor Hum). This report outlines the deployment of a short term geophysical field survey, performed during 2013 in Windsor, Ontario, Canada, aimed at monitoring the airwave signals associated with the Windsor Hum. The summary of the low frequency sound array deployment is presented and discussed.展开更多

Around this theme,Marx went beyond the perspective of religious criticism and gave priority to the analysis of the modern political state in the field of civil society,lightening the limits of political liberation and the path of human liberation.展开更多

Finally, the obtained results are illustrated by numerical simulations.展开更多
