چکیده

The present work concerns a system aimed at enhancing a target talker under varying signal conditions based on the use of several di erent types of information or \cues". Toward this end, an architecture designed to combine separately operating estimators is described and evaluated. The architecture is currently implemented using spatialand periodicitybased enhancement algorithms, and evaluated using a male target talker and female jammer talker under several spatial and target-to-jammer ratio (TJR) conditions. Using a TJR estimation algorithm, the implementation is shown to yield improved TJR under all tested input TJRs (-4, 0, 4, and 8 dB) and spatial conditions (target and jammer straight ahead; target ahead and jammer at 60 degrees). Improvement ranges from 1.4 to 4.5 dB.

Blind Separation and Deconvolution for Real Convolutive Mixture of Temporally Correlated Acoustic Signals Using Simo-model-based Ica

We propose a new novel two-stage blind separation and deconvolution (BSD) algorithm for a real convolutive mixture of temporally correlated signals, in which a new Single-Input Multiple-Output (SIMO)-model-based ICA (SIMO-ICA) and blind multichannel inverse filtering are combined. SIMO-ICA consists of multiple ICAs and a fidelity controller, and each ICA runs in parallel under fidelity control ...

Plants Role in Noise Reduction of Interior Walls (Comparison of Noise Absorption in Native Species and Non-Native Species)

Noise pollution is one of the most important features of architectural spaces having a great impact on the comfort of residents. Therefore, providing appropriate and sustainable solutions for noise pollution control is essential. Today, with the use of man-made synthetic materials, it has been tried to improve the sound performance of buildings. The purpose of this study is to show the characte...

The Perception of Multiple Broadband Noise Sources Presented Concurrently in Virtual Auditory Space

The effect of spatial separation on the ability of subjects to hear both sounds in a pair of concurrent broadband sounds presented in virtual auditory space was examined. Results suggested that this ability relied strongly on differences in the binaural cues delivered by the sounds, and stimulus pairs could not be separated if they delivered the same binaural cues. A relatively simple model was...

Source separation based on binaural cues and source model constraints

We describe a system for separating multiple sources from a two-channel recording based on interaural cues and known characteristics of the source signals. We combine a probabilistic model of the observed interaural level and phase differences with a prior model of the source statistics and derive an EM algorithm for finding the maximum likelihood parameters of the joint model. The system is ab...

Monaural Source Separation Using Spectral Cues

The acoustic environment poses at least two important challenges. First, animals must localise sound sources using a variety of binaural and monaural cues; and second they must separate sources into distinct auditory streams (the “cocktail party problem”). Binaural cues include intra-aural intensity and phase disparity. The primary monaural cue is the spectral filtering introduced by the head a...
