It is the greatest irony that Dyson, who make products that produce noise in excess of the pain threshold and who honestly have probably caused hearing damage to thousands, should make a hairdryer.<p>I don&#x27;t care how quiet they say it is, if their QA can approve their hand driers for sale, I don&#x27;t trust their sense of hearing!<p>EDIT: And vacuum cleaners. I have one (it was a gift), and it hurts to use.
