With the Airblade, Dyson pretty much perfected the air-blasting hand dryer. Pretty much -- those things are bloody loud. Never a company to sit well with imperfections, Dyson has now revealed the Airblade dB, which still manages to dry your hands in just 10 seconds flat while being 50 per cent quieter than the original.
The Dyson engineers took a look at the air turbulence generated by the first versions of the Airblade, and noticed that much of the sound generated was due to the speed that the machine's twin sheets of high-velocity air collided at to dry your hands. The Airblade dB tweaks the design, pushing air through two 0.4mm scallop-shaped apertures and increasing the distance between the sheets' starting points, helping to reduce the sound significantly. The process is explained in detail in the video above.
