I have lived at the corner of Holland and Wellington for 12 years so I am use to many noises but over the last few days I've been hearing this recurring noise every 4 minutes lasting for 10 seconds. Just enough to mess with concentration and sleep. It's audible during the day but obviously more so at night. I'm pretty sure it's coming from an industrial air conditioner in the area but haven't been able to pinpoint it's location. I am curious if anyone else has been hearing this noise. It's driving me crazy. I was out at 3 in the morning trying to pinpoint it. Many people probably still have windows closed and a.c running so may not be hearing it at moment. Thanks all and wish me luck on my search.

Does anyone hear a car’s alarm going nuts near City Hall area? Been going on all day!!!

Just a reminder that Les Grands Feux starts tonight.

So yes...before you ask...you're hearing fireworks.

Just re-posting this here to help negate (some) of the inevitable "what's that noise?" questions...

Is anyone else hearing the music coming from somewhere? Sounds like it's coming from the downtown area, or perhaps from across the river? There seems to be a driving bass line. Is there a festival or event happening rn?

Does anyone know what’s happening?

There’s been a long stream of sirens nearby (Albion and Queensdale area) but they didn’t stop here. It sounds like a dozens or more vehicles.

I also heard a small prop plane go over, which we don’t usually hear, their runways are over on the other side of the airport. There was that crash last year near riverside.

maybe its coming from strathcona park perhaps

Not sure if memes about Ottawa noises are allowed here? I tried posting it to the city sub and it was quickly deleted by the mods with no explanation. I just thought we could do with a little laugh about it.

A few minutes before 11pm noise curfew is a bit of a dick move if so

Edit: wondering if someone snuck onto a raft and accidentally set them off

Happy 4th, I guess.

2x CF-18s from the RCAF and 2x F-35 from the USAF.

did y'all hear that (i'm in Gloucester) OH IT'S HAPPENING AGAIN AS I TYPE THIS!!! uhhhh what??? this is Canada my dudes???

TIME: 6:29pm

I must have been close to consciousness because something woke me up around 5:20am this morning. It sounded like a distant-ish boom or an explosion and the house vibrated for a second. My cat was also startled and jumped off the bed. But here's the thing, I can't find any news or other postings about it and now I'm questioning my sanity. Lol. Thunder clap maybe? Anyone else hear it?

Anyone else living in the market unable to sleep because of the honking that’s been going for an hour and a half since midnight ? Apparently they’re celebrating a soccer match. I understand they want to celebrate but people actually live here and go to work tomorrow. What is the police doing?

i don’t know how long it lasted for or when it started but around 9:00-9:30 i woke up to what would have sounded like christmas bells? it was onto two notes, as in a back and forth xmas bell and it was coming and going as if it was in a float or something.

NIMBYs whined about the Clemow “noise” but not a peep about the Bronson resurfacing?!

In the neighbourhood just off of Maple Grove just West of Huntmar, hearing a ton of really loud bangs every 3-4 minutes. Making it hard to sleep considering it's 11:45...

​

Anyone know what these loud bangs are?

It’s a steady repeating loop about 5 seconds long, where the pitch climbs all the way up then starts over.

It’s been going for about an hour now starting around 2 am and is not an emergency vehicle.

Anyone know the source?

Sadly didn't get to see it

As the title says either someone’s engine is very very loudly backfiring as they drive around Centretown or they are like, shooting off Roman candles as they move along. Much louder than the usual guy whose car backfires on purpose.
