Future large-scale implementation of wave energy converts (WECs) will introduce an anthropogenic activity in the ocean which may contribute to underwater noise. The Ocean houses several marine species with acoustic sensibility; consequently the potential impact of the underwater noise needs to be addressed. At present, there are no acoustic impact studies based on acquired data. The WEAM projec...

This work investigates the application of photon mapping to model environmental acoustics. The resulting acoustic sonel mapping technique is a MonteCarlo based approach that can be used to model acoustic environments while accounting for diffuse and specular acoustic reflections as well as diffraction effects. This modeling is performed in an efficient manner in contrast to available determinis...

In this paper an application is described, where image registration to a model is used in conjunction with registration of acoustic (3-D) data to the same model to perform calibration of an optical/acoustic rig. This allows to register the video image with the depth map acquired by the acoustic device, thereby obtaining a single multisensorial image. Experimental results on both synthetic and r...

In this paper, we describe the design procedure for a wireless communication interactive voice response system. The application must work in a very noisy environment which has imposed many design constraints. We will address the sensible aspects of three components of the application: the voice activity detector (VAD), the automatic speech recognition (ASR) system, and the confidence measure (C...

One of the most studied areas for adaptive filtering is the one related to acoustic applications. Both the simplicity of the configuration and the immediate methods to evaluate the performance contributed to the popularity of this binomial pair: adaptive filtering and acoustic applications. Lately, a new step in acoustic application has been made, including the acoustic Multiple Input Multiple ...

In this article application of direct and indirect ultrasonic methods for evaluating and measuring porous materials are reviewed. Ultrasonic waves, due to their physical properties and wide frequency range can successfully be applied when evaluating the porosity of materials. Ultrasonic methods have many advantages when comparing them with other, non-acoustic measurement methods, which are also...

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 methods of acoustic spectroscopy are powerful tool for the study physical properties of condensed matter. The ability of these methods makes it possible to obtain important information for variety of materials concerning not only their mechanical properties. The theoretical principles of acoustic spectroscopy of some kinds of materials and structures perspective for application in electrica...

This paper reports on emotion recognition using both acoustic and language information in spoken utterances. So far, most previous efforts have focused on emotion recognition using acoustic correlates although it is well known that language information also conveys emotions. For capturing emotional information at the language level, we introduce the information-theoretic notion of ’emotional sa...
