Wow, I could definitely hear the sound in your video, nice job. Now, I just wonder what the heck it is. Did you have any physical sensations while the sound was going? How would one go about tracking that sound's source while it was active? Any sound experts around? Thanks for sharing

I heard a bird toward the end, I heard a gentle rain or perhaps garden waterfall (you said rain so must be rain), I heard bamboo or light wood chimes, I heard a plane, and either a Tibetan singing bowl or OTHER aircraft or table saw throughout.

The bird was most likely my cat, who jumped up in front of the camera. A Tibetan singing bowl, interesting analogy, their are multiple sounds throughout which include a plane but the one that is questionable is the high pitched hum.

Very interesting video i have no idea what the humming sound is but its very eerie..There is so many things going on in the world right now..I heard a sound one time were i live and it sounded like a low vibration similar to a truck that was idling it went on for about 10 mins and i live way out in the woods no trucks out were i am..Maybe its just the earth trying to give us some kind of warning..peace,sugarcookie1 S&F

I live in Edmonton and was awake at that time, that evening, and didn't hear anything (Had my window open as well). I would suggest it was probably some sort of industrial equipment within your area.

Industrial equipment at 1 am? I guess it is always possible but I would assume bylaw prevents the use of such devices at night-time. I would have had to have been pretty close by, somewhere within a 10 block radius each direction. I will have to look into potential construction in the area.

There is no such bylaw that I know of (in regards to workers). I live close to the CN rail station and the municipal airport and there is constantly loud industrial type sounds where I live late at night. Nothing really unusual about it. Perhaps in your area, that is not the case. But that doesn't necessarily mean it was coming from the "sky". It could just as well be equipment running nearby for a temporary project of some sort.

Not trying to say you didn't hear what you think you did, I'm just implying that I didn't hear anything unusual that evening so whatever it was, it was localized to your neighborhood.

Don't know if it's the same but iv'e heard electrical sounds like a transformer, very noticeable late at night,a very low decibel humming noise that pulsates..

It sounded creepy! I just wanted to let you know that if I heard that then I would've been freaking out too. It must've been strange in person, to send your husband out looking for a source. I live a few blocks from a train station so I hear all kinds of bangs and other spunds, but nothing like that, NOTHING AT ALL.... Hey, deadseraph, I'd love to hear a video of your train station sounds, you know, for scientific purposes. It might help some people rule out some things if they have a "strange sound" encounter...

Smart thinking getting this sound captured If it was me I would take this to a local TV station and see it they would put it on the evening news as I'm sure others would have the same question as to what it is / was. If this is a man made sound someone knows exactly what it is and will probably not have an issue commenting on it. It has to be a pretty weird unsettling experience but also exciting at the same time to hear something like that live.

Well I haven't been talking to many neighbors. Just several friends and a few people I am familiar with in the building. According to the people who live east and south of my location heard nothing. According to my husband the sound was just as loud where he went as it was hear. And he was further north-west than I was. About 7 blocks west and 9 blocks north. Everyone in my building who I spoke to heard nothing, because they where asleep.

Tonight I had my father listen to this. After hearing it he told me that it sounded vaguely like what it sounds underneath high voltage lines. Believe me, there are none of those over my head. My husband is a truck driver, has worked road and construction sites, and has been around lots of heavy loud machines. My father works for a gas company and has spent many years out in the fields. Dealing with gas leak emergency. Now, both of them said that the only noise they could liken it to was a hydro-vac truck. But having been around those trucks many times the sound, to continue for 40 mins straight, would mean they where running it FULL REV for that long. Most times you run that truck you run it full for 3-4 minutes then let off. My father's final answer was it sounded electromagnetic.

Because I am a wee bit OCD when it comes to information, I am going to make a general map image of how far I believe the sound traveled and try to figure out a source point. I will post when done.

ps- I am loving to feedback everybody. Thanks.

I actually live just south of the CN rail-line here and I have heard trains shunting. The screeching, banging noises they make. Sounds nothing like this, I completely agree,
