VALIDATION OF NEAR-FIELD SOUND PRESSURE ESTIMATION USING THE ACOUSTIC RADIATION MATRIX METHOD
Original language description
This work investigates the estimation of near-field sound pressure from a vibrating ETFE cushion using the Acoustic Radiation Matrix (ARM) method. ARM relates measured surface velocities to radiated acoustic quantities through a precomputed impedance matrix, providing computational efficiency for broadband analysis. The method is validated against finite element method (FEM) simulations at selected near-field positions in front of the cushion. Results demonstrate close agreement in both global trends and local modal features, confirming ARM as a robust and efficient tool for vibration-based acoustic characterisation of lightweight façade systems.
