摘要
Abstract
A noise abnormal rotary compressor is analyzed with sound quality evaluation method.Sound power level (A), loudness, roughness and sharpness are calculated as objective evaluation parameters , and the results indicate that the abnormal compressor has a poor sound quality compared with a normal one.Acoustic array technique can i-dentify target sound source of complicated shape accurately , and get rich sound field information compared to tradi-tional near-field measurement with a sound level meter.In order to diagnose the abnormal noise , the compressor sound sources are identified and located in full frequency range through acoustic array method .As a result, the key frequencies are diagnosed and the corresponding sources are also located , which provide the effective evidence for noise improvement.关键词
