We use various sort of household appliances in our daily life. Statistics point out that 98% of households have a refrigerator and 92% of households have a washing machine in Germany. Most of them runs for several minutes or hours per day. For example the refrigerator runs 24 hours per day or dishwasher runs 2 or 3 hours per day. Therefore their sound have an important influence on our daily life quality. Within the framework of EUREKA project 8684 Sound Quality, the sounds of various household products were analyzed and evaluated. The aim is to develop a sound label which characterize the perceptual features of the sound of the household appliances. Such kind of sound label helps and gives an orientation to the users to compare different machines with regard to their sound quality. Psychoacoustical properties are useful to develop a sound label. However there are various challenges regarding the optimal measurement environment, the measurement setup and the operating condition. The aims of this study are to summarize the results of investigations, which were conducted on three different household appliances and discuss the future milestones on the way to a sound label.
