Weird humming/buzzing/whirring noise near Whyte Ave?
Hey all -- so I live near Whyte Ave and all summer long I've been hearing this loud and persistent humming noise all day and night coming from around Whyte and 105 street. I've walked around that intersection a few times to try to pinpoint it but it's so hard with all the traffic noise, plus the sound echoes off all the buildings so it's almost impossible to figure out where it's coming from. It sounds mechanical, like maybe a generator or an industrial HVAC unit.
At first I thought it was from the apartment building construction site south of Whyte but that's more or less wrapped up now and the sound is still there. So now I'm wondering instead if it's coming from the rooftop of one of the professional buildings near the Metterra or something. I'm sharing audio of the sound that I took about twenty minutes ago if you're interested. I'm genuinely really curious as to what it is and where it's coming from.
Does anyone else live in the area and hear it too? What do you think it could be? Or am I going nuts?
