Dyson Supersonic Hairdryer
First they made vacuums. Then hand dryers, bladeless fans, and air purifiers. So in a way the advent of the Dyson Supersonic Hairdryer is barely surprising considering the company specializes in moving air powerfully. A 13-blade propeller within the handle is spun at up to 110,000 rpm and sits on a rubber mount, reducing vibrations and producing just one inaudible frequency to make the hairdryer far quieter than all others. Sensors monitor air 20 times per second as it flows upwards to control temperatures and to prevent burn damage to hair. Couple this to Dyson’s Air Multiplier technology and you’ve got a hairdryer that’s smaller, better balanced, and dries hair quickly and safely, all without being deafeningly loud.
