TY - JOUR AU - Gilroy, Layton E. PY - 2000/09/01 Y2 - 2024/03/29 TI - Comparison of SEA and PFFEA predictions of in-air and underwater radiated noise from a ring-stiffened cylinder JF - Canadian Acoustics JA - Canadian Acoustics VL - 28 IS - 3 SE - Proceedings of the Acoustics Week in Canada DO - UR - https://jcaa.caa-aca.ca/index.php/jcaa/article/view/1343 SP - 174-175 AB - The in-air and underwater experiments performed with a ring-stiffened cylinder are described. Broadband excitation was employed for the measurement of input mobility's response along with the resulting radiated noise in-air and underwater. These data were compared by statistical energy analysis (SEA) and power flow finite element analysis (PFFEA). The radiated noise predictions were made with a boundary element based post-processing software. SNAP, embodiment of PFFEA, underpredicted exterior radiated noise while SEAM, a software implementation of SEA, underpredicted interior noise. ER -
