The application is for ‘a hand-held appliance… a sound and vibration reducing hot-air blower’.
The design, which is shown in detail, is described in the application as a ‘hairdryer’, which could be made using sound- or vibration-absorbing material, and could be tuned to the resonant frequencies of the appliance.
The application reads, ‘The noise of the hairdryer is reduced by having a long fluid flow path, a coiled/looped/curved/s-shaped/zigzagged fluid flow path and frequency-attenuating lining material.’
Sketches on the application suggest the hairdryer would be similar in external form to other handheld hairdryers currently on the market.
Dyson would not comment on the application.
