Abstract : Defence Research Establishment Atlantic (DREA), with the assistance of Health Canada, has conducted an experiment involving the measurement of radiated noise from a ring stiffened cylinder subjected to a harmonic load in an anechoic chamber. This experiment was performed to provide validation data for structural acoustics computer codes being developed in house and under contract. These codes are used to predict the vibrations of structures submerged in, or filled with, a dense fluid and to also predict the resulting radiated noise.
