Wild speculation: I wonder whether loudness is actually a design goal, to make the dryer appear more powerful. A sizable number of people are skeptical of electric vehicles, because they perceive an earth-shaking vroooom to be an essential part of the driving experience. Could someone with industry experience chime in?

There are car makers who now use DSPs to process exhaust noise to play INTO the interior of the car to make people feel like they're driving! I drive a turboed car, turbos are naturally sound dampening, I'm totally fine with it being quieter as long as its actually faster.

To the speed point though, I'd probably drive a P100D because they're ridiculously fast...

VW even did this mechanically before switching to an electronic version. At least that means it's easier to shut it up: https://www.carworklog.com/2016/07/02/guide-disableturn-down...

I didn't know about the tube, I def would've plugged that. I have a MKIIV Golf-R and you can absolutely hear the "Soundaktor in action, its so goofy...

This, frankly, is my favorite sound mod -> https://www.youtube.com/watch?v=g_owsz8Za_Y

Same here, it's a beast. I've done a slew of other VCDS mods if you're interested. 5 brake lights instead of 3, tighter lane keep (tesla-like), power windows after door open engine off, enable menus while driving, rest-of-world dynamic headlights, brighter blind spot indicators, hazards on skid, no seatbelt chime, the list goes on and on. And open that center console if it doesn't open!

Non-commercial vacuum cleaners are acoustically engineered to be loud for this reason. Other examples of intentional loudening include the opening of car doors and aluminum beverage cans.

I suspect that the loud "powerful" noise level was selected to be in line with Dyson's brand image.

One good thing the EU did was to end this pointless rat race with anti-noise and efficiency legislation. No single vendor could have done it, because consumers equal loudness with effectiveness in a vacuum cleaner.

> consumers equal loudness with effectiveness in a vacuum cleaner.

I wonder how many consumers believe this versus how many actively seek out quieter vacuums.
