A friend told me about the following and I am wondering what you think the sounds could be? Interesting....

I have watched a few of them. The first one has a link that shows a map...that one is interesting too.

The City said it was them sharpening and resetting the blade on a grater. They acknowledged it is extremely loud but did, indeed, occur at the times "Wookey" was filming. They've had lots of complaints, evidently.

It would seem, as it is now, the mystery is solved but a few YouTubers still think it's a conspiracy.

Seems to explain it to me and honestly... sounds like industrial work to my ears.

"Electromagnetic noise" according to this University of Saskatchewan professor (1:40 in this video). Note that the video is from 2012 so it's not the "sharpening the blade on the city grader" that is claimed for the recent sounds:

Thanks. It is so interesting. When the first link, "Strange Sounds in Terrace Canada" is finished...you have a choice of a link that is a map and it is longer with discussion. You always have to wonder:-)

Hers is a link to a story about loud booms like the ones reported here.

Wow..thanks...that was really interesting. I did see one that happened in Finland that had that noise like Terrace, Canada had. Somehow, it seems that sometime ago there was a thread on mc.com about a boom and people wondering about it???
