background in many industries, noise is attributed as the most prevalent harmful agent threatening workers' health. geographic information system (gis) is an applicable surveying tool in civil engineering. but, the use of gis for noise and hearing loss screening seems to be partly a new approach. objectives this study aimed to apply gis in noise and hearing loss screening in the production hall...
Muffler is a part of the vehicle exhaust system that absorb or reflect sound waves to reduce exhaust noise. One of the most important determinants of a muffler performance is the amount of attenuation that has on its input wave; this parameter is known as sound transmission loss. Four - mic standard test is one way to determine this parameter which is used in this paper. In this study, a test d...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
People perceive, understand, and read the environment through senses. Vision hearing, two most effective senses in sensing space, provide much more lasting information. The mechanism of action eyesight hearing determination factors affecting these are especially important terms space design. study, it is aimed to reveal how what extent visual sensations affect design isolation together. In this...
1. Introduction To develop new man-machine interfaces and new communication systems, clarification of human multi-modal information processing has become a crucial, challenging and interesting topic. Self-motion perception is well known as a multi-modal information process influenced by visual, postural, and somatic information. However, we do not always use all of these kinds of information to...
This paper presents a telemonitoring system in an habitat equipped with physiological sensors, position encoders of the person, and microphones. The originality of our approach consists in replacing the video camera monitoring, not well accepted by the patients, with microphones acquiring the sounds. The sounds are analyzed and not stored in order to maintain the person privacy. We present the ...
Psychophysical and physiological evidence shows that sound localization of acoustic signals is strongly influenced by their synchrony with visual signals. This effect, known as ventriloquism, is at work when sound coming from the side of a TV set feels as if it were coming from the mouth of the actors. The ventriloquism effect suggests that there is important information about sound location en...
Gear drives are one of the most widely used transmission system in many machinery. Sound signals of a rotating machine contain the dynamic information about its health conditions. Not much information available in the literature reporting suitability of sound signals for fault diagnosis applications. Maximum numbers of literature are based on FFT (Fast Fourier Transform) analysis and have its o...
