A questionnaire survey was conducted to evaluate the economic value of sound quality of hairdryers using contingent valuation method. In this experiment, two stimuli inducing the unpleasant and pleasant impressions were presented to subjects based on the assumption that the former sound was emitted from the original product and the latter from the product with improved sound quality. Subjects were asked how much extra they would pay for the improved product in addition to the price of the original product. The questionnaire also sought personal attributes of each subject such as age, annual income, subjects' experience of being distracted by the noise of hairdryer, points checked when buying roducts: performance, price, etc. The obtained results were applied to a logistic regression analysis. Consequently, the price for the improvement of sound quality was estimated as being 469 Japanese yen, which is approximately equivalent to 12 % of the original price of a hairdryer.
