Estimating the Velocity Profile and Acoustical Quantities of a Harmonically Vibrating Loudspeaker Membrane from On-Axis Pressure Data
The velocity profiles of rigid pistons, supported radiators, clamped radiators, Gaussian radiators, and real loudspeaker drivers can be approximated using only a few terms of their Zernike expansions. The computed profile allows for the extrapolation of far-field pressure data, including off-axis behavior without requiring the use of anechoic rooms. The authors explore a method to perform forward and inverse sound pressure computations for circular radiators with nonuniform velocity profiles. Acoustic parameters of a harmonically excited resilient, flat, circular loudspeaker in an infinite baffle can thus be computed.
