The modern day call to prayer.
I could do without all the bird noises though, the sea gulls here are incredibly annoying.
Music doesn't help? Everyone at our office has headphones on with music exactly to stop hearing distracting background noise.
Nothing really changes for me when I go remote - same music.
I guess the industrial grade hearing protector industry would take a major hit though.
Site managers in North America rarely want to hear this, since it's more expensive and supposedly prevents close collaboration and encourages slackers, but that's just a bunch of BS. It's absolutely fantastic to just be able to close your door and have peace and quiet if you need to get into flow. Much better than being forced to wear headphones all day, for noise-cancellation or forced-music-listening instead.
Where did you get this idea from?
At best, companies have team rooms that hosts 5-8 people but not individual offices.
Most of the time we all have our doors wide open, it's glass doors, mostly glass walls, very bright, very modern. Everybody is welcome to stop by at any time when the door is open. Door closed means "please don't disturb unless it's an emergency". People close doors to have longer discussions, to have confidential discussions, or to have peace and quiet.
The doors basically serve the same purpose as headsets. They just make more sense and are more ... human.
Yes, some offices house more than one person. Typically 2, some have 3. But the employees in this situation are quite content with this and could request single offices at any time.
Besides, while they are good in cancelling e.g. aircraft engine noise, the active part does nothing to prevent e.g. human voices, and even high end headsets are far inferiour to dirt cheap industrial hearing protection where passive isolation is concerned.
I don't want to have to drown out ofice noise by blasting my ears with noise. I find having to wear any head/ear device a nuisance, and I tried a lot (fwiw cheap on ear Sound Blaster Jam V2's were unexpectedly comfortable and also great sounding to boot).
I have tankfully worked from home for the most part of the last decade (no, what was called WFH during the Covid lockdowns is not the same at all).
It’s not white noise, though: https://cambridgesound.com/learn/sound-masking-101/
(The trial was winter of 2019, then something happened in spring 2020 to keep us from going forward…)
