As the quality of consumer products has a direct relation with consumer confidence, excessive noise and abnormal sounds in consumer electronics will not only affect product experience, it may have negative impact on the perception of quality and brand. In order to improve performance, some products feature motor speeds exceeding 100,000RPM, resulting in high wind noise and coupled structural noise. It is becoming indispensable for manufacturers to build quality and reliability into their R&D, production and probably also in the after-sales maintenance processes to ensure product reliability and quality, so to enhance user satisfaction, build trust and reduce product recalls.
