近期，我院包国治老师的“Identification and contribution analysisof vehicle interior noise based onacoustic array technology”研究成果在《Advances in Mechanical》上发表。
This article proposes an advanced far-field acoustic hologram for vehicle soundsource identification and investigates amethod of performing contribution analyses in the far field. The hologram is applied for statistically optimized near-fieldacoustic holography used to identify vehicle sound sources (internal and external). An dvanced far-field acoustichologram is first proposed to improve the spatial resolution of low-frequency sound source locations in the far field. Inaddition, an acoustic contribution analysis based on near-field acoustic holography is used to provide a direction forlow-noise optimization design. Next, a new sound source identification and low-noise technology is explored via theaforementioned methods and applied for sound source identification and acoustic contribution analyses for a vehicle.The analysis results showed that in the process of sound source identification, the contribution of each sound sourcecan be simultaneously sorted, and this finding can help guide research on the low-noise control of a vehicle.
