If the customer isn't sure, then engineering companies should take pride in selling them what they need, not in pulling funfair-grade chicanery on them for a petty increase in share value
We can hardly blame the engineers when it's simple marketing and economics: they are designing for what are common (mis)perceptions of what constitutes "quality". I feel there is a trend now towards quieter and more efficient/lower power products, and ultimately it's us as consumers that drive these trends. However...
We are also manipulated on every turn. Look up 'nudging'.
Incidentally, in Japan, products like hairdryers and vacuums tend to be much quieter, probably to do with density of population.
