abstract = "Inverse methods are widely used for reconstructing radiating noise sources based on limited measurement data. The inverse pellicular mode analysis (IPMA) is an effective approach that uses pellicular modes as basis functions, reducing the number of required measurements while maintaining
reconstruction accuracy. The accuracy of source reconstruction using IPMA strongly depends on the strategic selection of measurement locations. In this study, IPMA is applied to reconstruct the radiating noise of an engine cover. The effects of different numbers of measurement points and varying
distances of measurement locations are systematically investigated. Additionally, the influence of random errors in amplitude and phase within the measurements is considered to identify optimal measurement positions. The reconstructed sound fields are evaluated by comparing the predicted sound
pressure levels at designated far-field target points.",
