Different signal processing methods are explored to extract individual arrivals from
frequency spectra that include interfering direct and multipath arrivals. Specifically, spectrum …

In measurements and numerical modelling of wave propagation, undesired interference
between direct and multipath arrivals can be reduced using Fourier-based signal processing …

The ambisonics format is a powerful audio tool de-signed for spatial encoding of the
pressure field. Anunder-exploited feature of this format is that it can bedirectly extracted from …

The measurement principle described in the present paper was developed and applied
within a sound field assessment task of the Brite-Euram research project PIANO which …

In the ultrasonic NDE of materials, spectral analysis of backscattered echoes is a useful tool
for flaw detection, frequency-shift estimation, and dispersive echo characterization. In order …

An optimal and noniterative method is described by which selected portions of any spectrum
can be fitted by an all‐pole spectrum. The method makes use of the spectral matching …

The focus of this paper is the estimation of the dynamic transfer function between two
outputs of a linear system subjected to an uncontrolled and generally unknown excitation …

A novel technique for analyzing the acoustic fields generated by ultrasonic transmitters
when radiating into an layered, inhomogeneous media is presented. The technique is based …

Many signals, such as speech and other animal sounds, FM radio waves, machine
vibrations, and sonar and radar echoes, exhibit frequency characteristics that change over …

A new approach to time-scale expansion of short-duration complex acoustic signals is
introduced. Using a subband signal representation, channel phases are selected to …
