| Abstract(E) | Identifying the factors behind wide-area and transient acoustic phenomena that cause discomfort to vehicle occupants has long been a challenge. In this study, we developed the world's first simultaneous measurement system featuring a 12-channel acoustic probe array. We designed the requirement specifications and commissioned its fabrication to a specialized vendor. This system enabled synchronous measurement of three-dimensional acoustic intensity vectors and airflow velocity within HVAC duct noise. Through coupled data analysis, we quantitatively visualized spatiotemporal noise fluctuations, providing valuable insights into complex acoustic phenomena. |
