Vacuum Cleaner Noise Troubleshooting

Industry: Consumer Products

Applications: Troubleshooting

A vacuum cleaner and floor care product manufacturer chose Sound Answers to understand the main sources of noise that contribute most significantly to the overall sound pressure level and annoyance to the operator. Operating noise measurements were taken in a hemi-anechoic chamber and a quiet room to better simulate a typical operating environment. Multiple microphones, a binaural head, and sound intensity mapping were analyzed in both narrowband and 1/3 octave bands to determine key noise sources. A number of design recommendations were made which the customer has decided to incorporate into this product line and to use as design guidelines in all future platforms.
