The paper deals with the optimization of the acoustic properties of selected noise sources of household appliances, specifically washing machines. The introductory parts are focused on the analysis of parameters affecting the quality of the product, the so-called "general features of product quality" and a proposal of a new methodology for their evaluation. Attention is paid mainly to a new type of properties, the so-called customer-oriented acoustic properties of the product. Methodologies have been developed for laboratory measurements of psychoacoustic properties and noise visualization, which are then tested in an anechoic chamber by measurement with an acoustic camera and a psychoacoustic head. Methodologies after their evaluation are used in measurements in real conditions. A listening test is created, the results of which can be used to evaluate practical measurements and determine customer-required acoustic, customer-oriented properties. [ABSTRACT FROM AUTHOR] |
