A methodological approach for noise reduction in household appliances

In this paper we report on attempts to reduce the sound-power level by a new systematical approach. A step by step method integrating different design models as Triz, Theory of inventive problem solving by Altshuller, FBS by John Gero, anticipatory failure analysis, and a specific noise knowledge database is proposed in order to systematize the assessment phase and suggest improvements onto the system. Noise database, created by authors, collects an already known set of effective technical solutions on noise reduction, well organized to be offered to the user when needed.
