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.
