  • Concrete Construction Health Effects

    It’s no secret that working in Concrete Construction is dangerous. The immediate safety hazards are well known. Getting speared or cut on rebar, sore from the hard physical labor; cuts or punctures from nails; and struck by tools, materials or equipment can all cause injuries. Add to that possible falls especially at the leading edge; cuts or shock from powered equipment; burns or explosion ...

  • Measurement and bio–dynamic model development of seated human subjects exposed to low frequency vibration environment

    In this study, the effect of posture, vibration magnitude and frequency on seat–to–head (STH) and back support–to–head (BTH) transfer functions has been studied under vertical sinusoidal vibration. Twelve healthy male subjects participated in experimental work to measure vertical vibration transmitted to the occupants' heads in three representative postures (erect, ...

  • Identification of quality attributes of automotive idle sounds and whole–body vibrations

    The aims of this study are the generation and comparison of the semantic spaces of vehicle idling sounds and vibrations and the determination of their quality dimensions. In this study, two different sets of quality attributes were developed for idling sounds (34 attributes) and whole–body vibrations (22 attributes). In contrast to prior investigations, the results demonstrated that the ...

  • Human emotional response to steering wheel vibration in automobiles

    This study investigates what form of correlation may exist between measures of the valence and the arousal dimensions of the human emotional response to steering wheel vibration and the vibration intensity metrics obtained by means of the unweighted and the frequency weighted root mean square (rms). A laboratory experiment was performed with 30 participants who were presented 17 acceleration time ...

  • Optimisation of whole body vibration analysis for suspended cabin tractor semitrailer

    This work has been conducted to find out the health risk associated with suspended cabin tractor semi–trailer driving work. Suspended cabin tractor semi–trailer drivers are exposed to whole body vibration (WBV) during their work. Some drivers suffer from low back pain caused by vibration. The practical significance of applying suspended cabin type of tractor semi–trailer was tested at different ...

  • Field measurements and assessment of vibration serviceability of as–built long–span concrete floor

    Vertical vibration serviceability of an as–built concrete floor, whose 41.55 m span is currently the longest in China, are investigated in this paper by field measurements and numerical analysis. A vibration monitoring system were designed and installed on the floor. Different types of human–induced excitation are simulated such as single person walking, multi–person walking at the same pace ...

  • Canarina CUSTIC software · noise dosimeters and modeling · introduction 5

    Noises are irregular and disordered vibrations including all possible frequencies. The intensity of a sound I can be expressed in decibels with the standard equation: L=10 log(I/I0) where I0 is the quietest sound most people can hear, the threshold of hearing 10-12Wm-2.  When the ratio is between ...

  • JNIOSH - reproduction of multi-modal sensation

    The Company On 1 April 2006, the National Institute of Industrial Safety (NIIS) and the National Institute of Industrial Health (NIIH) were amalgamated into a single, administrative institute known as the National Institute of Occupational Safety and Health, Japan (JNIOSH). Of all research institutions under the Japanese Ministry of Health, Labour and Welfare, JNIOSH is one of the top ...

  • Cognitive degradation after exposure to combined noise and whole-body vibration in a simulated vehicle ride

    This study investigated if vehicle noise and whole-body vibrations produce negative after-effects on performance in an attention task and on ratings of alertness, difficulty, and annoyance. The task was applied before and after exposure, and after a rest. Participants had degraded performance immediately after exposure in all conditions, but no effect was found after the rest. No main effect was ...

  • VIBRATION NOISE & ITS IMPACT ON HUMAN HEALTH

    Vibrational Noise is one of the major Environmental problems in Industrial Plants. The Noise Study under taken in Chinese Unit no.4 of Thermal Power Station (TPS) Jamshoro. The level and Frequency characteristics of the prevailing Noise recorded in detail, at Basement Area Feed Pumps, Turbines, Boilers, F.D.F, I.D.F & Compressors, and found that the level of Noise is higher at Boiler House and ...
