Bayesian sequential estimation applied to three-microphone tube data with circumferential sensors extends valid frequency range for porous media characteristic impedance and propagation coefficient by handling observed phase discontinuities.
The impulse responses are windowed to eliminate all unwanted reflections except the direct sound and the direct reflection from the test- ing samples
