I'm just glad they identified the source of the hum, many people are impacted for years by unexplainable sounds, and it is maddening.
It took me and my neighbours a month to find the source of a hum that was resonating with our windows. It was torture, with midnight walks and lurking around potential sources, mapping nearby industrial sites, and questioning our sanity, while our windows were vibrating without a stop. We were very lucky to track it down to a badly installed air conditioning vent 200 m away.
