The low-frequency humming/vibration noise was very intense at this time. It was so loud inside that it prompted a walk around the neighbourhood in the afternoon to see if it could be located outside. The noise was evident outside, but it was difficult to discern precisely where is was coming from. A one-hour walk until about 4:00 determined that the noise was prevalent in the Ranchridge Way / Ranchview Road area.
At 8:00 PM, I partnered with the President of the Ranchlands Community Association for another frigid walk outside in this area to see if the two of us might be able to locate the noise. We did isolate an area, outside, where we could hear the noise quite plainly. We were not able to say for certain if the noise was coming from one of the houses we were behind, or whether we were standing in an area where the noise was bouncing and reflecting off of buildings, etc. This was a significant find in our search for this noise's source.

Outside, in and around our house, the low frequency noise that has been disturbing us was very loud. It sounded like it was "all around" us - a common characteristic of low frequency noise. This characteristic makes it difficult to locate the source of low-frequency noise, too.
