The $400 supersonic dryer is up to eight times more powerful than conventional devices.
“But we’ve turned conventional hair dryer design on its head. The Dyson Supersonic™ hair dryer has a thirteen-blade axial flow impeller balanced inside the handle, spinning at up to 110,000 times per minute. Milled to a tolerance of 15 microns, it has one inaudible frequency and a rubber isolation mount prevents the motor from vibrating against the inside of the handle, reducing the transfer of noise between the motor and the case.”
