Strange noises reported around North Battleford

And when it turns out to be a hoax will you apply the same standards and relinquish your internet access?

The point isn't that the bass is gone it's either attenuated (i.e it loses it's lower frequencies) or it "distorts" the mic (i.e. the bit of the mic that has to vibrate to capture the sound waves doesn't have the capacity to capture the full frequency range).

Ah. But if it was attenuated as you say, how do you tell without having a different recording of the same sound from the same area at the same time using equipment capable of picking up a wide range audio frequencies?

And I thought distortion was primarily caused by amplitude, not frequency.

hey easy,,,nobody knows, we are all just talking about it....so at this point nobody is right or wrong

No, distortion is caused by a lot of things, in the case of frequency it's caused by a membrane not being able to vibrate properly which creates distortion.

As far as the first question. The sound itself has relatively low frequencies, which wouldn't have been picked up by the phone mic... so unless youtube is somehow recreating these out of thin air, they shouldn't be in the videos...

In other words



Go to about 1:38 and see what happens.

Noise can travel a long way at night - it's called ducting - mostly a phenomena known for improving radio & TV reception at long range it can work for sound too.

So this is what I reckon it probably is.

What I don't understand is, if these noises have always been around, why are people suddenly hearing them now? Why are people being awakened at night. Should we not be used to hearing them if they have always existed around us?

I'm quite curious. I almost hope I get to hear some of these myself in my region...

You do hear it all the time... every heard a sporting event, where you can pick out individual voices, but it seems impossibly far away?

Here's a weird thing, radio waves travel huge distances at night, not in the day.

I used to work at a radio station in Arkansas. At NIGHT the station was occasionally picked up in Florida. During the day you couldn't get it 60 miles away.

That's a massive difference and a well understood phenomena.

I would like to hear why noise travels further at night.
I can think of a few reasons obvious.
less dust particles in the air
less ambient noise

Ah, I see. Thanks for the explanations.

So about the frequencies in the video, are you making an 'educated guess' or have you done an analysis? Have you used audio software to determine the range of frequencies in the video and compared that to tech specs of the phone's mic capabilities? I'd be interested to see that, if you had.

Deny Ignorance, I dont see how thats the same thing at all.

Just logged back in and there are over 4 pages of new comments!
Its going to take some time to read through, obviously there is a great interest
in these noise reportings!

Thanks everyone, and cheers!
I'll be back later on to comment, and answer!

I'm a professional musician and producer (not famous... Yet) and am used to hearing demos and bands recorded on all sorts of mobile devices. I also have professional monitors.

The very first time I heard it I noticed it sounded way to well recorded (the sound stays consistent even though the camera moves) and covers a much wider frequency range than expected for a mobile phone mic.

Not a pro analysis (though that'd be easy to do); just my ears + my experience + my knowledge.

Seems pretty obvious to me..

The point is that sound travels very strangely at night and can seem very very deceptively close.

I'm in Lancashire, England. I had the news headlines on the radio earlier today, and right at the end of the 3 minute slot, there was some mention of a lot of phone-calls to authorities regarding a variety of strange noises. Unfortunately, it was pretty much one or two sentences only, and my attention was distracted by someone cutting me up on a roundabout, so I didn't catch it all!

I've tried to look it up on the BBC news website, but can't find any reference to it. I wondered if anyone else from this neck of the woods had heard it?

edit on 26-1-2012 by captainnotsoobvious because: (no reason given)

I am sure that the most OBVIOUS thing about the noises is they are not coming from a sporting event or a car. Just my 50yrs worth of being on this planet + experience + having heard the noises my self + wondering how YOU hear anything anymore with sound systems in autos being what they are these days

Im here in Ireland and as I was letting my dog out to go for a pee I heard what sounded like a weird plane that was heading to crash??, I cant explain it....but my dog was barking like a maniac, I just closed the door n thought it was weird but didnt think anything of it till my friend mentioned hearing it... and now Iv looked online and now everywhere is getting it!.... wtf is it?? my brain actually hurts from trying to figure out what the noise was. :S

the only thing i could find on the bbc site was a link on this page

electromechanical sound
found this link on google its a bit over my head by the way!

prb.aps.org...

come to think of it doesnt a loudspeaker produce electromechanical sound?

Thats just the thing, I have been a night owl and star gazer most all of my life. I have heard noises, many noises in different cities over the years and not once have I heard the sounds that many are suddenly hearing now. I consider myself to be hypersensitive and overly observant by nature. So if these new sounds that are being heard have always existed, I would not even bother questioning them because I would be familiar to them already.

One of the reason why noise travels further and better at night is simply because the air is colder thus denser.
Sound travels more efficiently in a denser medium.
I used to live like 3Km away from a highway, during the day you could barely hear it, but at night, you can almost count the cars passing by.

I live in the midwest and they always plow the streets at night and put salt on the road at night to help prevent the ice, but some of the noises on the videos do not sound exactly like snow plows not to mention people who live in areas where it snows frequently in the winter time are usually able to tell the sound of a snow plow just like hearing a garbage truck pick up a dumpster. These sorts of sounds are not unusual at all. I don't think it is snow plows. I think it is something else and that is why the scientist is speaking up but not giving any or enough specific details to say what it is exactly.

Something strange is going on in my opinion.
