Natural?

I watched a video the other day and scientists were saying the noises are nothing to worry about and its this natural electro magnetic phenomenon thing. This does sound like a valid explanation but again, why did we JUST start to notice this. If it is so natural than why is such a fuss being made now?

From my experience of these noises in Windsor/Detroit Ontario/Michigan I know FOR SURE this is not natural.  Its such a noise that it feels like it pounding your chest. It also happens near every night only for no more than 1 year. This is NOT natural.

Regular Industrial Noises?

I have seen MANY comments on youtube videos of people saying "The noises are just from the factories and plants" I personally have heard the noise in Windsor, Ontario Canada and this is NOT some regular industrial noise. This noises is so loud it can be heard across the whole city and within 5 km or around 2.8 miles you can FEEL the vibration in your chest, it almost feels and sounds like you are feet away from a ship running aground.
