I wonder how much of this sound pollution disproportionately affects autistic people. We need to make our soundscapes accessible.
Now if the same could be done for bad LED lighting. I hate being somewhere where the whole room is strobing at 100 hz.

One thing that can help is pressing the turn signal lever with less force than is needed to latch it. This should cause the indicator to flash three times and then stop. It’s an operating mode I wasn’t aware of for decades.
Not all cars do this, german car feature? (only VW's I've driven from 2000's onward seemed to have)

Going into Sears used to drive me nuts. My parents finally accepted that I was actually hearing something that they couldn’t, but it took a while. I don’t know if it was the loss prevention system that was doing it, or what. All I could do was localize it down to being anywhere remotely close to the entrances. And the closer you got, the louder it got. These days, my tinnitus is constantly ringing at about that same…
Could have been the pulse frequency of old magnetostriction loss prevention rfid tags. The tone is not meant to be audio, but might be inadvertently emitted by the electronics.

Or the idea that the humans are just blissfully unaware while their 'hyper' cat/dog is stuck inside a home with some device screaming 24/7, LED lights flashing, etc.
To this day, not one person in the spec reviews in whatever overseas OEM electronics or those split AC units (which are fantastic in one regard) reflects on persistent light in a room where people are sleeping? The worst is encountering AC units when arriving at a hotel that do not have a "display" button to turn off the 20C display in white LED. Are the actual people that make these and make those decisions just tou…

I moved the TV, XBOX, a $50 PC and almost all of my optical discs (but no books) over there because (1) I won't be so mad if a copy of Disney's Frozen gets pissed on (he's a tom), and (2) if it does the disc will be undamaged and at worst I can discard the package.
That room gets really dark and it doesn't have a switch controlling an overhead light so turning off a floor lamp and then sneaking out the door without creating an opening for the cat to escape (though he's much more inclined to hide than run) leaves me quite happy for the little LEDs and stuff that create just enough light to get from the couch to the door.
I had almost forgotten about the “Mosquito” devices for deterring youths that became ubiquitous in some areas during the late 2000’s and early 2010’s. They were quite expensive and I know of a few people who got annoyed and specifically vandalised them due to the annoying sound.

I think the dogs can hear our induction stove with ultrasonic whine, but somehow my cat will sleep blissfully in a room with a VGA CRT whining from 30-80 kHz (perhaps quieter than the stove), and used to sit in front of a CRT TV whining at 15.7 kHz so loudly I couldn't stand it without headphones.
(In the past I have volunteered as a sound man for live music events but I have never been at a venue which I thought wasn't too loud in terms of absolute sound pressure or in terms of there being audible distortion in the amplifiers & speakers, so I haven't made a habit of it. My son won tickets to a 38 Special + Foghat show that we went to last week, I didn't mind the loudness much but it was clear to me they were pushing the sound system just a little too hard.)

How so?
I brought some class actions years ago alleging the unlawful use of this tech for essentially ads purposes: https://topclassactions.com/lawsuit-settlements/lawsuit-news... and https://www.freeadvice.com/legal/lisnr-responds-to-lawsuit-t...

I assumed that most of the normal consumer-level stuff is (perhaps very deliberately) insensitive to sounds that human ears are insensitive to? The common codecs, for sure, tend to have rather harsh cutoffs around 20kHz (the common sampling rates being 44 or 48kHz, and the Nyquist frequency half of that, 22-24kHz, so you have to start filtering well before?) Plus, I'd rather not walk around with a laptop. But perhaps…
Studio Six Digital makes the very useful app AudioTools. They test all iOS devices to create generic profiles for the built in mics. They’ve found them to be very consistent which is kind of remarkable for a consumer cell phone device. More info here: https://studiosixdigital.com/audio-hardware/generic-audio-ha...
What does the author use to measure sound and create those graphs? I'm interested in automatically monitoring an annoying noise that's coming from a neighbour.
