Composites of shape memory alloys (SMA) with a matrix have been widely studied to suppress the propagation of damage. In these studies, the SMA is used as an actuator. A multi-functional SMA as both sensor and actuator is suitable for constructing intelligent material, such as a material with a sensing and suppressing function. The damage of materials is related to the amount of strain. We studied the use of SMA wire parts as sensors to measure the amount of strain for damage estimation. The acoustic emission (AE) signals induced by phase tran ....etc

Introduction

3D audio system developed by William.G.Gardner.

Sound cards, multimedia speakers, video
games etc.. Are marketed as having 3D capability.

A new technology called Acoustic Environment modeling has emerged which combines basic 3D technology to simulate natural acoustic scenes.

3D AUDIO SYSTEM

A 3D audio system has the ability to position sounds all around a listener.

Here the sound is created by headphones, but th ....etc

Acoustic cryptanalysis is a side channel attack which exploits sounds, audible or not, produced during a computation or input-output operation. In 2004, Dmitri Asonov and Rakesh Agrawal of the IBM Almaden Research Center announced that computer keyboards and keypads used on telephones and automated teller machines (ATMs) are vulnerable to attacks based on differentiating the sound produced by different keys. Their attack employed a neural network to recognize the key being pressed. By analyzing recorded sounds, they were able to recover the tex ....etc

Thermo acoustic Refrigeration is based on the principles of creation of temperature gradient from sound waves and this theory was first developed in 1960s. Unlike vapour compression system, Thermo acoustic engines uses inert gases which is safe and no adverse effect on the atmosphere like the depletion of ozone layer and global warming.

Even though acoustic Refrigeration is efficient and cost effective its commercial application is warranted the need of more R&D efforts for technology up gradation and standardization without which its eff ....etc

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc
