Customer satisfaction is proposed to evaluation a product quality whether good or not in the development of market with customer-oriented. In this paper, the importance of the customer requirement is introduced in sound quality evaluation. During the subjective evaluation procedure, the roughness coefficient and average roughness interval are applied to calculate the basic importance of customer requirement. Subsequently, the amending factor set is conducted to correct the basic importance of customer requirement based on the Kano model. As a result, the final importance of customer requirement is obtained, which can transform the customers’ subjective requirements to engineering improvement targets. Moreover, the test on noise working condition is carried out. The results indicate effectiveness of the proposed method.
