biophysical profile (bpp) test is the most commonly used antenatal test of fetal well-being. purpose of this study is determining the influence of acoustic stimulation (as) on bpp testing time. about 55 pregnant women at 35 to 42 weeks who referred to department of obstetric & gynecology at university of medical sciences, tabriz, iran, were selected randomly. we used abdominal ultrasound guidan...

The sound generated by viscous ow past a circular cylinder is predicted via the Lighthill acoustic analogy approach. The two dimensional ow eld is predicted using two unsteady Reynolds-averaged Navier-Stokes solvers. Flow eld computations are made for laminar ow at three Reynolds numbers (Re = 1000, Re = 10; 000, and Re = 90; 000) and two di erent turbulent models at Re = 90; 000. The unsteady ...

We perform a comparative statistical analysis between the acoustic-emission time series from the ancient Greek Athena temple in Syracuse and the sequence of nearby earthquakes. We find an apparent association between acoustic-emission bursts and the earthquake occurrence. The waiting-time distributions for acoustic-emission and earthquake time series are described by a unique scaling law indica...

Can we hear the sound of our brain? Is there any technique which can enable us to hear the neuro-electrical impulses originating from the different lobes of brain? The answer to all these questions is YES. In this paper we present a novel method with which we can sonify the Electroencephalogram (EEG) data recorded in rest state as well as under the influence of a simplest acoustical stimuli a t...

The excitation mechanism of low degree acoustic modes is investigated through the analysis of the stochastic time variations of their energy. The correlation between the energies of two different modes is interpreted as the signature of the occurrence rate of their excitation source. The different correlations determined by Foglizzo et al. (1998) constrain the physical properties of an hypothet...

BACKGROUND Objective acoustic analysis is a key component of multidimensional voice assessment. OperaVOX is an iOS app which has been shown to be comparable to Multi Dimensional Voice Program for most principal measures of vocal function. As a relatively cheap, portable and easily accessible form of acoustic analysis, OperaVOX may be more clinically useful than laboratory-based software in many...

This study investigates the influence of both phonotactic and acoustic cues on the segmentation of spoken English. Listeners detected embedded English words in nonsense sequences (word spotting). Words aligned with phonotactic boundaries were easier to detect than words without such alignment. Acoustic cues to boundaries could also have signaled word boundaries, especially when word onsets lack...

This paper presents an analysis of acoustic pattern registration for a new means of human computer interaction. It discusses the relationship between variations in correlation coefficients and signal pattern registration parameters including signal sampling rates, amplitude digitisation resolutions and recorded signal lengths. Experimental results have confirmed that the accuracy of acoustic pa...

The purpose of this study is to evaluate the use of Acoustic Rhinometry in assessing surgical outcomes in sinonasal surgery. This prospective study was carried out from January till December 2001. A group of 44 patients who presented with nasal obstruction due to various rhinologic abnormality were examined with acoustic rhinometry pre and post-operatively. They were examined with acoustic rhin...

The paper presents our recent work on the acoustic and physiological feature analysis of affective speech. An affective speech corpus is first built up. It contains passages read in neutral state and ten typical affective states selected in Pleasure Arousal Dominance (PAD) space. Physiological data, including electrocardiogram, respiration, electro dermal data, and finger pulse, are also collec...
