That noise is very loud, and that makes me wonder why there aren't hundreds of people in the street freaking out.

These noises appear to be being heard all over the world, are there any vid clips showing masses of people who hear the noise?

HAARP aye?

How do you know it isn't a bowl of corn flakes?

If you can prove to me it's NOT a bowl of corn flakes I will be impressed.

It is so easy to make these by adding a soundtrack to a video clip, I've almost been tempted to make a few, just to screw with family members (since they get off on messing with my head, it's only fair). The only way I will ever believe this crap is if I hear it myself, in real life. And so far, I have not heard anything of the sort.

Ok if these strange sounds videos are hoaxes, where are they getting the sounds, and why is it a world phenomenon? Also why recently, and why are they mostly all different? And why does radio and tv shows talk about them?

Surely any noise made by HAARP would be much less than the daily noise made by the Sun?

You do know what HAARP actually is and does?

I didn't make the title, its from the youtube video

Is HAARP legit?

I was just going to bed at 4am in UK London last night, and I heard that sound again but I was too late with my video camera.

I only heard it because I don't have double glazing in one room. So maybe people don't hear this sound because of double glazing. And sometimes it happens at night.

This is the 4th time I have heard this sound BTW. Each time it was slightly different.

Very eerie sounds indeed. It does sound like tormented souls crying out.

But who knows if these videos are for real. When I hear the sounds myself I will know.

Hummm we just had a BIG Halloween party a few weeks ago so I know you can buy those sounds on a CD!! It's all packed away now but most of it is something recorded backwards.

I believe harp is real as you only have to look at the news and see for yourself weather manipulation that's happening. I'm pretty sure the gulf stream going out if sync proves something is wrong. Can't say I've heard noises in the sky to suggest harp but I have seen extremely odd cloud formations which indicated a electrical ionic reaction of some sort was taking place.
