Abstract
A drying apparatus such as a hand-held hair dryer comprising a housing including a nozzle and containing an air outlet and a fan assembly contained within the housing for generating a flow of air from the outlet. The apparatus further includes a flow guide including a plurality of holes therein contained within the nozzle, the flow guide forming a closed shape in cross-section and having open ends. The flow guide is separated from the nozzle so as to form a space between the nozzle and the flow guide for flow of air therethrough. The flow guide tends to attenuate noise generated by operation of the apparatus by lowering the frequency of the noise.
