Quality conversion of non-acoustic signals for facilitating human-to-human speech communication under harsh acoustic conditions

Harsh acoustic conditions limit the effectiveness of human speech communication to a great extent. There is a consensus that even at moderate SNR levels, traditional speech enhancement techniques tend to improve the perceptual quality of speech rather than its intelligibility. As an alternative, non-acoustic contact sensors have recently been developed for noise-robust signal capture. Although ...

Conversion of sensory signals into perceptual decisions.

A fundamental problem in neurobiology is to understand how brain circuits represent sensory information and how such representations give rise to perception, memory and decision-making. We demonstrate that a sensory stimulus engages multiple areas of the cerebral cortex, including primary sensory, prefrontal, premotor and motor cortices. As information transverses the cortical circuits it shows...

Optical Detection of Acoustic Emission Signals

Piezoelectric transducers, long used in the generation and detection of ultrasonic waves, have more recently been the detector of choice for acoustic emission signals. Optical probing methods, however, have several important advantages for acoustic emission studies: (1) they have an inherent broad frequency response, free from mechanical resonances, (2) they do not interfere with the acoustic w...

Characteristics of Acoustic Emission Signals from Composites

Certain characteristics of acoustic emission (AE) signals from graphite-epoxy composite specimens were correlated last year with the mechanical behavior of the materials. Moisture degradation, which reduced the ultimate strength, resulted in a change in the AE amplitude distribution early in the loading history. Also, AE having distinct frequency spectral types tended to occur at or near singul...

Blind Separation of Underwater Acoustic Signals

In last two decades, many researchers have been involved in acoustic tomography applications. Recently, few algorithms have been dedicated to the passive acoustic tomography applications in a single input single output channel. Unfortunately, most of these algorithms can not be applied in a real situation when we have a Multi-Input MultiOutput channel. In this paper, we propose at first a reali...
