Sound-quality Objective Evaluation of Air-cooled Refrigerators Using Sound Intensity Testing
摘要
Abstract
To quickly and accurately learn the sound quality characteristics of air-cooled refrigerators, a new test and analysis method for sound quality evaluation of multi-sources noise was proposed. Firstly, the accurate localization of the noise sources was performed through sound intensity testing to fully understand the frequency characteristics of the noise sources. Then, through sound quality testing, the characteristics of the sound quality parameters were obtained. Finally, the sound quality of the products was evaluated by combining the sound quality testing result with the sound intensity testing re-sult. The results show that the loudness and fluctuation of the refrigerator noise are mainly affected by the noise of the air cooling system and the condenser;the sharpness and roughness of the noise are mainly affected by the compressor noise. It implies that under the condition of multi-source noise and the complicated frequency combination of the noise signal, sound intensity testing is very helpful to quickly and accurately identify the noise sources and contribution of the specific frequen-cy-band noises which affect the sound quality objective parameters.关键词
