Dyson Supersonic: A Good Day
Long regarded as a top styling essential, the hairdryer has been a staple on almost every woman’s vanity. Despite coming a long way from the non-portable version—it consisted of a bonnet attached to the pipe of a gas stove—designed by French hairstylist Alexander Godefroy in 1890, the conventional hairdryer still has a long way to go. Dyson’s engineers worked to solve these issues (device bulkiness, heat damage, the risk of hair being sucked into the filtre), eventually coming up with the Dyson Supersonic, a lightweight model that utilises a fast, focused airflow and is equipped with intelligent temperature control that helps protect the hair.
It took the company several years to properly develop and test the Dyson Supersonic in its state-of-the-art laboratory. The dryer is powered by the Dyson digital motor V9, the company’s most advanced mechanism, running up to eight times faster than that of other hairdryers. Its compactness allows for it to be placed in the handle rather than the head, making the dryer lighter and less cumbersome to maneouvre. Dyson’s patented Air Multiplier technology helps regulate the airflow, creating a controlled jet of air that assists drying and styling. A glass bead thermistor measures temperature 20 times per second, transmitting it to the microprocessor that regulates the heat expelled from the device. In addition, the Dyson Supersonic has four heat settings, three airflow settings, as well as a cold shot.
Noise reduction is also one of the hallmarks of this device. A team of aero-acoustic engineers discovered that inserting a component called the axial flow impeller into the motor effectively reduces turbulence and swirling. By adding an extra two blades (the usual number of motor impeller blades is 11), the sound frequency drops to a range that is barely audible to the human ear.
