Analysis and Evaluation of the Noise Quality of Vacuum Cleaners
The noise emitted by the vacuum cleaner developed by Company A when working on a hard floor is taken as the research object.Sound samples are collected,and the sound pressure level and objective psychological acoustic parameters of the sound samples are calculated.The subjective evaluation is conducted using paired comparison method.Through multiple linear regression analysis of the data,a noise quality model is established,indicating that pitch and sharpness are the main objective factors affecting the noise quality of the vacuum cleaner.It also reflects that A-weighted sound pressure level cannot fully reflect the subjective perception of the human ear towards the vacuum cleaner.
