I’m glad they’re trying to reduce noise exposure.

But for me, 65 dB is the equivalent of getting hit by a car at moderately-low speed, so 85 dB would be the equivalent of getting hit at extreme speeds, all the time, again and again. It’s horrifying to think that it is the standard permissible painhammering level.

Redesign of Work Space in Order to Reduce Noise Health Effects.

F Veljovic, S Burak, E Begic and I Masic, Materia socio-medica, Jun 2019

Noise represent an unwanted sound that endangers human health in multiple manners and in work setting causes reduction of productivity on one side, and increased waste on the other. Noise pollution occurs when the ear is exposed to the volume of sound that is disturbing, stressful or directly damaging hearing, but also acting on the organism as a whole.The aim of the article is to examine the vulnerability of workers working on the "press" machine, and to carry out an analysis and examine the press operator workplace, then perform the noise spread measurement in the press operator work area and compare the current measurements with the permissible levels and analyze the time period of worker exposure, as well as presentation of the effects of noise on productivity and workers health. The aim of the article also includes the proposal for decrease of noise pollution.A noise analysis at the workplace of workers working on a "press" machine was performed, which is exposed to a high impulse noise due to which the quality and quantity of production are reduced. For the purpose of calculating the noise level for one working day at the press operator site 1, 2 and 3, it is necessary to analyze the noise level in time. Operators spend most of their working hours at stations 1 and 3 where the measured noise level is Lm1 = 94.7 dB is taken, or at position 3, Lm3 = 97.2 dB. The measured noise level at these locations without the operation of the press is Lm1 = 80.1 dB, or at station 3 is Lm3 = 80.1 dB.It was found that these operators working on the machine in question were exposed to a noise over the limit for more than three years. Their health problems that arise as a result of noise exposure are documented in their health charts. In order to achieve uninterrupted work at the press machine, during the eight hours shift, a noise correction is required to allow the equivalent sound level to fall within one day to the permissible 85 dB. In this regard, we consider the fact that we have known that the press produces a sound level of 110 dB, and that there is a reverberation (reflecting) sound. Given the technical characteristics of the plant, the reduction of the sound intensity of the source itself is not possible, so the suggestions of the technical solution will be based on reduced reflected sounds and to prevent the spread of direct sound to the operator.Workers are exposed to permanent noise during a working day, which produces a number of consequences for the health of the worker, but also the employer and the community. The imperative of the employer is to reduce the number of rejects, increase profitability and to have a positive impact on the health of the individual.

Not much study on the topic:

Lo-jak was the first of many products to be actually effective at deterring professional thieves. Alarms only work at the nuisance-crime level, both as deterrence and as offender.

The article mainly focuses on backup beaters, on crosswalk beaters, and on proposed low-speed beaters so that electric cars are at least as painful as gasoline cars.

I live next door to a company with a lot of trucks. In the early hours of the morning, they get started loading up their trucks for the day. They also do snowplowing, so when there’s a snowstorm they start even earlier. Luckily, the noise doesn’t bother me like it does a lot of people.

The backup beepers have become my notification that it’s time to go to bed, sunrise will be soon. I now associate that sound with relaxation and the comforting feeling of the end of a long day. Kind of like an industrial lullabye. I guess it’s probably not effective in its purpose as an alarm for me.

The industry replacement to the cock’s crow.

Here’s one you don’t see too often, thank goodness.

Some wall wart or something left something behind.

Fortunately I thought, “Maybe I’d better unplug the extension cord before trying to extract that.” This was after reaching for it, and almost grabbing it. I think it was on the non-grounded side.

What is with these sockets that grab and won’t let go? Not to mention cheap shit plugs. Combination is not healthy.

Wisconsin_Platt · January 22, 2020, 11:49pm

Still has the little tab at the top to prevent you from plugging in a grounded plug

Shut down computer, wait, unplug so I can sleep. zeouw So it didn’t shut down that time. I have to restart, and spend several hours checking on it, before I am permitted to sleep.

“But why do you have to unplug it?”

SO I CAN SLEEP! The computer has too many lights. The power strip has too many lights.

At what point did we drop the Menu button on Android, lmao. It was so useful

Have you considered musician’s earplugs? They provide up to 25dB attenuation without muffling sound. I’m going to a lot of shows this year and took the plunge to get a custom fit pair with Etymōtic filters. This kind of thing seems like it could be useful in daily scenarios as well if you need to lower the volume on the world while still needing to hear things clearly - something regular plugs definitely don’t do.

I bought some sheets of these on Amazon for my electronics. They dim the lights significantly while being visible when I need to see if something is on:

(They also make sheets you can custom cut for oddly shaped lights, as well as 100% blackouts.)

My current mold-my-own plugs are rated 26 nrr. They don’t deliver, but they fit. Standard one-size-fits-all don’t fit my ear canals, so they hurt, and they don’t protect at all.

Does anyone know of a browser with good find-in-page capabilities?

Firefox only allows one search term at a time.

Waterfox can run Findbar Tweak, but it’s no longer available, so that’s moot.

MarjaE · February 5, 2020, 11:46pm

For my previous question, I’m using Regex Find-in-Page tool.

Dealing with a few pdfs I’ve been unable to process and compress in Ghostscript. Turns out that the images are composed of hundreds of tiled jpegs. Which is bad enough. For whatever reason, Ghostscript won’t compress to fit my page sizes in pixels. So regular images get overcompressed and these images go uncompressed.

I think can use Ghostscript to separate the pdf into separate text and image files, and probably rasterize the image file, and then cpdf to stamp each page of the text file over the correspondng page of the image file.

There may be an option to disable them when it’s not on in the bios, or you could flick the psu switch to off. Had similar problem. Glass case rgb motherboard.

The worst lights are on the power supply for my hard drive, and on the power strip.

Is it just me or has the Twitter interface recently gotten worse?

tinoesroho · February 26, 2020, 7:24pm

twitter is doing a rolling rollout of their new, worser design

tinoesroho · February 26, 2020, 7:25pm

my computer is covered with copious amounts of electrical tape. paint might also be an option!
