The rest of the electric fan market has shifted over the last ten-ish years to noise-efficiency. Meaning the most air movement for the least amount of noise. So we've seen new blade shapes, smarter motor designs, enclosures that attempt to dampen the noise, and so on. And Dyson's Air Multiplier could, in theory, have done well in that competition but they care more about form than function, so they stuck this tiny little motor with a higher RPM in the thing which has made it extremely loud for the amount of air that it can move.
In terms of noise-efficiency, it sounds as loud as fans from the 1990s and before.
For example the Marpac Dohm has an actual spinning fan inside designed to generate white noise. But you can find digital noise simulators who can do: industrial sounds, water, fan noise, nature, and so on.
That and (perhaps) making the pattern asymmetric should restore the noise.
Dyson is just something of a rarity in that he's selling consumer devices to the public, rather than defense hardware to governments.
Everyone in on the "design" scam relies very heavily on the assumption that the more expensive goods work better than cheaper ones. As previously mentioned, there is no rational case to be made for buying one of these.
If my laptop computer lasted up to 37 years, I would likely still replace it after no more than 5, with another that cost half as much both in terms of initial investment and operating cost, while still offering greater capabilities.
I'd just take that $600 I might have spent on a lamp, buy Cree stock instead.
I can only assume Dyson pivoted from making a jet engine.
they're noisy and expensive, but they work really well.
I see you're new to Dyson's business model. Keep in mind, these are the guys who make a $400 fan in a niche full of $10 competitors.
