Delight design for hair dryer sound

This paper describe the procedure to realize a comfortable sound of a hair dryer by using delight design platform technology based on the sound quality metics and the 1DCAE methodologuy. 1DCAE is defined as the design concepts, methods, and tools that cover the early design stage. The output of 1DCAE is input as the design requirements to a conventional CAD/CAE system, which transforms the design requirements into an actual product image. The CAD/CAE results are then fed back to 1DCAE to verify the overall functions. The 1DCAE concept is expected to realize design innovation and more innovative products.We applied the delight design platform technology concept into Sound Design. Product sound design platform based on 1DCAE can realize a 1D simulation environment at the early design stage of product development. The output of 1D simulation (time domain) is input of Sound Quality Metrics calculation, then we can express delight factor as a function of Sound Quality Metrics. The above design process enables the hair dryer with comfortable sound.This research was supported by New Energy and Industrial Technology Development Organization (NEDO) of Japan, and we would like to thank them for their assistance.
