Geesh. Last week, a sleeping homeless person was assaulted in Rotterdam by someone throwing a heavy rock on his head while he was sleeping. The victim is still in a coma (and will probably never awake from that).

Warning: horrible video from our national TV program 'Opsporing Verzocht'.
https://youtu.be/rRd_eV8Q9sg

The perpetrator is still at large. Police have tracked his movements somewhat. He appears to travel by train a lot. Images show him at Mechelen station (Belgium), one day before the incident in Rotterdam. Police think he travelled south by train to Antwerp and Brussels after the attack.

I just read that he has probably travelled onwards to France, and did the same thing there now. Just today, a sleeping homeless person was killed in Lyon, by a guy throwing a heavy pavement tile on his head full force.

International train travellers are asked to look out if they spot the man, and if so, call the police immediatly. Do not approach. Deranged serial killer. (His face is clearly visible on the video I posted above, with permission from the justice department)

Police do not rule out the possibility of him returning to the Netherlands to strike again. Or anywhere else where trains can take him.

Homeless folks: do not sleep near railway stations, or sleep in shifts keeping watch.

Same problems across the channels, it's just too common for homeless people to be randomly attacked / have bricks thrown at them. 8 years ago we had big headlines when 3 teenagers tried setting a homeless eldery man on fire, and he was lucky a teenage girl ran to put out the fire on his sleeping bag before he got hurt

Oh God, I have Fee Fi Fo Fum above me, stomping around like he doesn't know how to walk like a normal human being, my next door neighbour hallmate who occasionally bonks, and now my next door neighbour not-hallmate who's apparently found someone with a high libido (Alongside their own) to keep bonking.

I am cursed to be surrounded by banging/creaking. And I'm still not getting any myself because I'm still a general mess, just now it's a product of my trans-ness rather than my brain being a complete mess.

Quietest night in a flat

I was pretty damn impressed when they were holding a big festival weekend from Friday to Sunday. The music was being blasted from on top of a hill from some seriously powerful speakers. It reverbed my windows from about 3 miles away. People living in the towers had it even worse because they had no buildings dampening the noise in between. The local council's approved the festival for every year foreveeeeeeeeer

[martinuzz]

This spring I was working at a festival, and the decibel meter read 103 decibels in the production office, about 500 meters away from the stage tent the music was coming from.
The fluorescent lamps vibrated out of their fixtures.

That was.. Too loud. I believe our legal maximum is 92 decibel. 103 decibel is uhhh.. almost 4 times as loud.

(Ofcourse, FOH was radio'd and told to turn it down)

Over 70 decibels is hearing loss range
Over 85 is warning: risk range
Over 140 decibels is when your machines aren't making sound waves... They're making shock waves 

[martinuzz]

91 or 92 decibels is our legal max for outdoor events. I think for indoors (pubs, music venues) it is 80.
Festivals all advertise and sell earplugs nowadays, so that's progress.

[McTraveller]

What weighting is that? And at what distance is that 91-92dB limit for outdoor events?

In the US, OSHA has a time-based limit. ≤90dBA is allowed for 8 hours/day. 92 goes to 6 hours, 95 is 4, 97 is 3, 100 is 2, etc.  90dBA is a "typical power tool" sound level using the US dB-A weighting scale.

My kids can talk at 80dB; I can't imagine how you'd have an indoor sound level limit of 80dB.

I think it's funny that venues hand out earplugs. How about just turn down those volume knobs, eh? (Although to be fair: sometimes that doesn't work; we have a sports venue around here where the crowd gets up to 116dB... you really do need hearing protection to go to those events.)

I only know some about this because of work and because I do sound engineering at our church and we try to keep it around 90dB tops during worship, although sometimes it does peak (5 second average) around 95.

One time I visited an ear nose throat doctor to deal with pain in my left ear

They asked me if I had a noisy workplace

I told the doctor I taught kids. She burst out laughing

You get three problems where I am with music venues

1. Bad acoustic design. We've got some absolutely gadunkus places with god tier acoustic design that were made for orchestras or choirs 1000 years of darkness ago and most of them were designed to make it easy to hear a tiny flute or some castrato harvested by the catholic church even in the back rows of the audience

2. Crowd vibe is a real thing. I remember seeing the Hu in Wales and in London. In Wales the venue was much smaller, quieter and the crowd fewer. But it was 25% metalheads, 25% Uni students, 25% the Welsh Mongolian community and 25% pensioners. Best night ever. The London crowd was just large, passive blob of very tired guys drinking overpriced beers whilst their girlfriends rocked on by themselves. When it came to sound the Welsh crowd were in sync with the band, the London crowd wasn't feeling it. You raise the volume on the shite crowds the crowds just get noisier - not in the same way as a crowd getting louder. Just noisier. Like random noise. People shouting because they can't hear their friends next to them, amplified by a million people. Then you get the other end of the spectrum where you could probably go acoustic for a Taylor Swift, K-Pop or Cold Play concert to thousands because the entire crowd is singing the lyrics off by heart

3. Sound guys / artists who want BIG NOISE. Also concert goers who want BIG NOISE. Lots of people into music concerts, night clubs and the usual tinnitus enjoyer circles have gotten accustomed to big noise. It is what it is

Also there are studies that show more noise = more drinks sold so there's that angle. But I think it really is just big crowds overpower musicians when the venue has shite acoustics coupled with expectations of more noise = more energy = more vibes + overenthusiastic sound engineers who paid for all that bass so they WILL flashbang the crowd with bass for every penny spent

I only know some about this because of work and because I do sound engineering at our church and we try to keep it around 90dB tops during worship, although sometimes it does peak (5 second average) around 95.

Churches usually have pretty good acoustics

Huzza!

That makes me suspect that your USA dBA is a slightly different metric than our EU dB. 80dB is a pub's music playing so loud that you need to get up close with friends to be able to talk with them. 90dB is for large outdoor stages, to have the music be loud and clear at about 100m.
Over 90dB is where you really start to feel the bass in your tummy.

For some bands playing indoors in pubs though 80dB is too low to properly do amp feedback harmonic effects. Not sure if they are right, or if they just want to make more noise.

the Welsh Mongolian community

All six of them? 


Though I am now wondering how many folks of recent Mongolian descent live in the UK.

[Frumple]

From a quick google at least 1800 as of the last time they collected the information back in '21, so probably a bit more now? Not a huge amount but it's more than enough to build a small community around.

That makes me suspect that your USA dBA is a slightly different metric than our EU dB.

It's not an EU vs US thing, it's that dBA and dB are different ways to measure loudness. Far as I can tell the measurements are the same on either side of the pond, dBA in the EU is the same as dBA in the US, dB in the US is the same as dB in the EU.

[McTraveller]

Straight "dB" is related to the physical sound pressure level.  dB-A is a weighted version, which is intended to reflect perceived loudness, not physical sound pressures.  There are other weightings, but not as commonly used.

[martinuzz]

Learn something new every day. I hadn't heard of dB-A before.
