This has nothing to do with noise cancellation as in Bose headphones - it merely adds more noise to mask out the background noise. In effect just giving a constant, but higher level sound environment. Constant noise is less disruptive for sleep.
Sound-mufflers chuck acoustic sleep blanket at the noise-plagued
Ever wondered why the Bose-style noise-cancelling technology can’t be made to work for rooms? Actually it can, but getting it to muffle sudden noises such as dogs barking or gunshots, so your sleep isn’t broken, and doing so at consumer prices represents a whole new set of challenges.

Re: Tired of being woken up ?
Actually I believe the US and or the UK military had Peril Sensitive Sunglasses for their nuclear bomber/C3I aircraft pilots. When the nuclear flash was detected they went opaque to protect the wearers eyes from blindness. Before that they were issued with an eye patch so that they could switch eyes if blinded in one. Cheerful thought for Tuesday Aftenoon.

Re: From the website:
120V 60Hz limitation must be pretty arbitrary in such a system. It can't be relying on 60Hz for a reference frequency or anything, and indeed I'll bet the internal electrons are all nicely queued DC style so the IC's can work and speakers don't carry their own 60/120Hz hum.

Of course, British versions will cost more because of the excessively large monster plugs used there.
The design goes back to the 1940s, and one could argue that by modern engineering capabilities, it is a behemoth. The plug and socket incorporate various safety features not found on other systems around the world.
BS 1363 is a British Standard which specifies the common single-phase AC power plugs and sockets that are used in the United Kingdom. Distinctive characteristics of the system are shutters on the line and neutral socket holes, and a fuse in the plug. It has been adopted in many former British overseas territories. BS 1363 was introduced in 1947 as one of the new standards for electrical wiring in the United Kingdom used for post-war reconstruction.

Re: That's why I keep an OLD computer
.. because I sleep so well to spindle and fan noise ..
In winter, when the computer room^w spare bedroom door is open (summer, it's closed because the aircon is on in that room) the soothing sound of the fans in my server lulls me to sleep. And the waste heat keeps the upstairs nice and warm :-) [1]
Have to put a stairgate across the door, otherwise BiggestCat goes and sleeps up against the outflow fans on the acoustic case and the server gets hot. Also reduces the risk of cat-puke on the equipment on top of the server case..
[1] But not a warm as the old Dell 2U server did. Thankfully, the new server is considerably more quiet as it doesn't have 6x15K RPM SAS drives whirring away.

Not noise cancellation. Not at all.
As noted above. This isn't noise cancellation. Noise cancellation on open spaces is astonishingly difficult, and it only works in headphones because the distances involved and the acoustic environment is so small. (And why the heck does everyone think Bose invented this either?) Once you have a reverberant field you are pretty much sunk.
You have been able to buy noise blanketing systems forever. Before they were electronic, a wire brush rotating inside a metal cylinder made for a very effective white noise generator.
All this offering is is an expensive way of making the noise source an IoT device that looks cool. There is no real technical innovation from the actual acoustics point of view over something you could buy 50 years ago.

>And why the heck does everyone think Bose invented this either?
Because Bose marketed it heavily at consumers, often in the same glossy newspaper supplements as they have long advertised their other wares.
There is lots of aviation technology that only later is affordable for Joe Punter. Additional examples include e-ink (several kg of flight manuals cost fuel) and eyeball tracking.
In any case, it doesn't bother people where a technology originated from... they only need to know who they can buy it from. Oh, and they don't want to buy a 'how', they want to buy a 'what'.

Noise
Or we could just give the police the right to tell your selfish neighbour to shut the fuck up or go to jail - now. I dream of all the selfish cunts in this world suffering unimaginable pain in the next or even better instant retribution. Selfishness is one of the greatest malignancies blighting the 21st century and if there is a god then it's failing to wipe out the selfish. No wonder I'm an atheist.

Part of me agrees wholeheartedly with this; another part feels that the sentiment is inherently, er, selfish.
Selfishness is one of the greatest malignancies blighting the 21st century and if there is a god then it's failing to wipe out the selfish.
Sadly that does appear to be true; hardly a day goes by without my seeing a parent effectively teaching offspring that it's OK to be selfish - not by words but by example. I doubt if I will ever hear the words "have some consideration for other people" ever again.

Analogue noise cancellation
In the '80s I lived in a flat in an old Victorian house, one Saturday a similar house across the road was having a very loud party, several irate neighbours had called the police who came, told them to 'turn it down' and duly went. At which point the reveller turned it up again. Eventually my neighbour from the top floor knocked on my door and asked if I would accompany him across the road to ask the party people to turn it down, I said sure but I didn't think we would make much difference. Anyway we went over and began talking to the guy who actually lived there and was about as ratarsed as one could get, while I was nattering on the doorstep to an incoherent idiot Gary walked in pulled a rounders bat out of his shirt and beat the crap out of the stereo. Silence! even the party goers were so stunned they said nothing.
The moral is $249 against a £5 or less rounders bat? I know which one I would consider buying.

wind and rain
I don't think I'm the only one that loves the noise of wind and rain battering off windows/roofs.
nothing beats night in tent, or in motorhome when it's like this.
A device that plays that sound realistically would be good.
of wait... that'd be like - a set of speakers - I've got them... will give it a go and save my 249 dollars.

Re: wind and rain
Well yes i'm all with you on the kipping in a tent with rain... BUT:
1/ Said tent must definitely be known to Not leak.
2/ Must sport a sewn in ground sheet (drafts) that also does not wick damp.
3/ Plenty of warm bedness with puffy sleeping bag etc.
4/ (big ask this buut) Listening to some poor sod putting their tent up in the pissing rain in the dark.
4a/ much prepared smugness...
ps: canvas tents are a better sound as the plitt-plitting is more damped, nylon test are harsher sounding, but nicer in soft rain. swing/roundabouts etc
