Abstract
Good sound-feeling is more important than noise strength for industrial products, especially for household appliances. In the paper, the control method of good sound-feeling of vacuum cleaner is researched based on the theory of soundscape. For the purpose, a special method of sound forge and evaluation technology (SFET) is utilized. For the method, first the spectrum of vacuum cleaner is analyzed to obtain its spectrum characteristics. Second by means of spectrum forge technology, the frequency spectrum of vacuum cleaner is modified and compiled to make the testing samples. Third based on the sound subjective evaluation, the optimum compiled sound sample of vacuum cleaner is acquired. At last, according to the optimum sound sample, the structure of product is modified to obtain product sound of good-feeling. In the paper, the spectrum of vacuum cleaner noise is analyzed, according to the spectrum, the method of sound forge is discussed. In the end of the paper, the virtual simulation of soundscape of vacuum cleaner is designed by means of some software to give an example of optimizing soudscape.
