A noise competitive

The other day I was  using the vacuum at home, and remembered I don’t like doing this be cause of the noisy, I like an environment calm and silent, I remembered too a show where they are talking about qualify employee to built a cool noisy for vacuum, I thought What?? that was in one of those Nordic countries, that man is be able to built a noise to invite the costumer to buy, so those artifacts has to be very competitive talking about features, and believe it or not that man can receive a lot of money just doing that because just few people in the world can know about the perfect noise of the vacuum to be more attractive a vacuum, so the industry knows how important is the noisy at the time to make a purchase decision then the sound should be not to laud and not silent, to me was really surprised knowing more about the vacuum industry, I’ve never imagined this before.
