A method of product sound quality classification and limit value evaluation based on satisfaction is proposed for the quantitative evaluation of product noise level by product manufacturers, product quality evaluation institutions, consumers and other stakeholders. Through subjective evaluation experiment and questionnaire survey, the relationship between product noise quality index and satisfaction degree was obtained. After comprehensive consideration of the current production level of the industry, affordability and consumer interests and other factors, the sound quality classification and limit assessment were carried out. The method is applied to household appliances and ships, and the product noise quality classification and limit evaluation are carried out to verify the effectiveness and applicability of the proposed method. The characteristics and problems needing attention when the method is applied to different fields and scenarios are discussed.
