The complexities of the Windsor Hum are astounding. The deeper we go into the investigation the more mysterious it becomes. We have recently looked at all the different industries along the river, and they all make one type of noise or another. All the noises sound different from one another, and no two are really alike. We are still seeking to find the elusive 30Hz + the extremely low frequency sounds that felt and not heard - The LF remains untied, undefined, and unknown to us. In the coming weeks we will have some new instruments to measure this phenomenon.
