We propose a new method of modeling a room transfer function (RTF) that uses common acoustical poles and their residues. The common acoustical poles correspond to the resonance frequencies (eigenvalues) of the room, and their residues are composed of the eigenfunctions of the source and receiver positions in the room. Because the common acoustical poles do not depend on the source and receiver ...

one of the fields of creation and practice expansion is an attempt to diversify and multiply melodic modules which can increase practical potentials in a musical system. the most fundamental element of a sonic- musical atmosphere (mode) is ambits of tone; in other words, it is a sequence of tones with specific frequency. therefore, melodic modules combination depends on acoustical features and ...

The modern use of ancient heritage sites can be, to say the least, challenging from an acoustical perspective. In fact, modern needs may require acoustical interventions in contrast with the preservation issues of the cultural heritage. This paper deals with this topic in an UNESCO designated world heritage site, the Palatine Chapel of the Royal Palace in Caserta, Italy. Since this chapel is cu...

OBJECTIVES There are four types of signals that are typical representations of vocal fold vibratory patterns. Type 1 signals are nearly periodic, type 2 signals contain subharmonic properties, type 3 signals are chaotic, and type 4 signals are characterized as white noise. High-speed imaging allows detailed observation of these vocal fold vibratory patterns. Therefore, high-speed imaging can ex...

Conventional acoustical methods for measuring the permeability or flow resistivity of a porous material require a priori estimation of the porosity. In this work, an acoustical method is presented in which a simplified expression (independent of both the frequency and porosity) for the transmitted waves at the Darcy's regime (low frequency range) is derived, and used for the inverse determinati...

This paper explores acoustical (or time-dependent) radiosity--a geometrical-acoustics sound-field prediction method that assumes diffuse surface reflection. The literature of acoustical radiosity is briefly reviewed and the advantages and disadvantages of the method are discussed. A discrete form of the integral equation that results from meshing the enclosure boundaries into patches is present...

This paper proposes an integration of the time-alignment information in the decision making for HMM-based text-dependent speaker verification. The principle is to consider acoustical score and time-alignment as joint observations for which a log-likelihoodratio is computed and compared to a threshold. It is shown that such integration has two distincts aspects, one being a kind of adaptation of...
