This is nice, it adds another dimension to the audio experience of the bridge-bay 'composite-system'

That was such an insane thing to discover my first time on the BART. I’m sitting there thinking a catastrophic accident is about to occur, but everyone else is just on their phones... oh, that’s just the screech!
From a Londoner's perspective, this is giving me tortured flashbacks to travelling on the Jubilee Line. It's physically painful to hear once you start speeding up inside the tunnels.
I travel on the Northern line on the London Underground to get to work and the sound of the trains nowdays hits 100dBA or more of extremely loud screeching: https://i.imgur.com/04YwBHJ.png
I went as far as lodging an official complaint and was told that to deal with capacity trains are running more often and faster than they have in the past, hence the increased noise. Furthermore due to the Northern Line having been built before environmental noise regulations were passed, it's exempted so Transport for London aren't planning on doing much about it.
At the risk of sounding like a curmudgeon - between always on ear buds and mass transit noise we're risking a generation of kids suffering hearing loss well before their time.

My backyard backs in to a strip mall with an auto mechanic shop. We hear a high pitch sound some times of the day and when we step outside to inspect, we only hear a different sound from the shop behind - a typical machine running, but not necessarily unpleasant. Turns out the walls are able to mask the lower pitch sound somehow and let in only the unpleasant higher pitch sound to the inside of the house. I am not su…
Have you checked for windows resonating? It would be surprising if walls were acting as a high-pass filter. Could also be electronic noise. I wonder what the machine is.
Air powered die grinder, drill, or impact gun. Or, if it sounds real choppy, maybe an AC TIG welder.
I’d bet die grinder. They’re not used all the time, and they have VERY high rpm sounds which are always terrible.

#314We just live with a very loud sound at our house. Run water for any reason. When you stop, some 0-15 seconds later an enormous sound reverberates thru the house. Plumber says its 'water pipes growing or shrinking, rubbing against the straps'. But it goes on for 10-30 seconds. No water pipe in the world moves that long/that much?
Could it be a drain pump noise propagating? Does it happens even when you don't send the water in the drain, but in a bucket?

Pretty much the only good thing about the lockdown was the massive reduction in sound levels in London. Just off Old Kent Road which means traffic noise dropped, plane noise disappeared[1], general hubbub of the feral children vanished, no late night parties at the community centre, etc. It was as close to blissful as I've encountered in London. [1] Normally one every 5-10 minutes from 0500 to 23000 since we're on He…
Lots of good things about the lockdown from the aspect of peace, quiet, nature, clean air, reduced light pollution, and more. It just comes at a cost that society isn’t willing to bear.

If its water hammer (as it sounds like it is)-- it can fatigue joints and valves and cause leaks over time. Water hammer can be fixed by putting hammer arresters at the right locations.
But - every tap in the house causes it! And the toilets. And the shower. And the outside hydrant. Where would we put such a thing?
IANAPlumber but the "water hammer" effect is usually very immediate and short. It literally sounds like a hammer hitting something.
What you're describing might be along the same principles but much larger, or it might be something else, but in any event it sounds serious. (No pun intended.)
Get a second opinion before a pipe bursts or comes loose, eh? If by "the outside hydrant" you mean a fire hydrant then I would call the city too.
Any chance of a video or audio clip?

#317There's a marina in the East Bay that has the same effect on some of the railings there. Much quieter though.

One of the stranger things I've read on HN.
If someone's grown up in the (eastern part?) of the state, the not-very-veiled subtext is quite entertaining with the typical HN cynical bit flipped on.
Cape-affiliated person here. Currently dealing with multiple issues. There is a powerful coterie of real estate agents, lawyers and regional government members here. The environment is invoked like a playing card to create battles of financial starvation and just as easily overlooked when it would interfere with players' plans. One must be very aware of neighbors' affiliations. It's all sport for the 1%, but families who inherited their parents' properties struggle to hang on to them.

Not a hammer sound, absolutely. An humming, thrumming sound. Rises and falls and a trailing off with a duration of 5 seconds.

#320I wonder what Mills College’s Center for Contemporary Music (CCM) will make of this.
