Detection and Analysis of Noise in Air Purifier |
| |
| Abstract: | Air purifier is a common household appliance,commonly used in places such as living rooms and bedrooms where people rest.Noise is an important performance indicator of air purifiers,how to correctly evaluate the noise of air purifiers is of great significance to human health.This paper performs noise testing on air purifiers.A-weighted sound pressure level evaluationand NR curve evaluation and A-weighted power level evaluation are obtained through a ten-channel synchronous test center frequency of 1/3octave band sound pressure level of 100 to 8000 Hz.Analyze the advantages and disadvantages of different evaluation methods and explore more suitable evaluation methods for air purifier noise. |
