| This study presents a comprehensive noise source analysis of a nitrogen generation system installed in an industrial production facility. The primary objective of the investigation was to determine the location of the dominant noise sources and to identify their respective sound pressure levels and frequency characteristics under operating conditions. Detailed measurements were made using a 16-microphone array combined with CAE Noise Inspector software for accurate sound field visualization and analysis. Experimental tests were conducted at three different locations within the system: the nitrogen generation unit (location 1), the nitrogen storage tank (location 2), and the exhaust pipe (location 3), with the latter further subdivided into three specific measurement points (3a, 3b, 3c) to account for variations along the length of the pipe. Each acoustic measurement session lasted three seconds, with data recorded at a high recording frequency of 204,800 Hz to ensure precise resolution across the frequency spectrum. The operating cycle of the nitrogen generator was divided into two main phases: phase 1, characterized by the transient sounds associated with valve actuation, and phase 2, dominated by the continuous sounds generated during nitrogen transfer to the storage tanks and exhaust. Recordings at site 1 captured both operational phases, while measurements at sites 2 and 3 focused exclusively on phase 2 in order to isolate relevant noise sources. The results provide a detailed and quantitative characterization of the acoustic emissions associated with the nitrogen generation process, providing valuable insights that can be used to develop targeted noise reduction strategies and contribute to future optimization of the system's mechanical design and operational efficiency. |
