Abstract

When using traditional non-parametric DFT methods,long reflection free acoustic impulse response measurements are required to accurately calculate the low frequency free field frequency response of a loudspeaker. It is shown that by combining parametric input impedance and acoustic impulse response models the associated parameters can be estimated from short data records yielding high resolution low frequency free-field frequency response measurements.
