Burden of disease from road traffic and railway noise
A quantification of healthy life years lost in Sweden This paper provides the first estimation of the health burden in terms of disability-adjusted life-years (DALY) of noise from the transport sector in Sweden. Assessments of health impacts of noise on a national level are still rare, but provide valuable tools for policymakers in order to prevent and abate environmental noise exposure.

The effects of noise on key workplace skills
This study explored the effect on memory and psychomotor performance of wideband noise (simulated in-cabin aircraft noise) at 75 dBA, which is similar to that experienced during the cruise phase of a commercial flight. The results from the tests were compared to the effects of a widely known and common metric on the same skills, namely, blood alcohol concentration (BAC). All 32 participants, half non-native English speakers, completed three different tests (recognition memory, working memory, and reaction time) presented in counterbalanced order, either in the presence of noise, with or without...
A cross-sectional study of hearing thresholds among 4627 Norwegian train and track maintenance workers
OBJECTIVE: Railway workers performing maintenance work of trains and tracks could be at risk of developing noise-induced hearing loss, since they are exposed to noise levels of 75-90 dB(A) with peak exposures of 130-140 dB(C). The objective was to make a risk assessment by comparing the hearing thresholds among train and track maintenance workers with a reference group not exposed to noise and reference values from the ISO 1999. DESIGN: Cross-sectional. SETTING: A major Norwegian railway company. PARTICIPANTS: 1897 and 2730 male train and track maintenance workers, respectively, all exposed to...
Whole body vibration exposures in bus drivers: A comparison between a high-floor coach and a low-floor city bus
Low back pain (LBP) is common in occupational bus drivers and studies have shown a dose–response relationship between whole body vibration (WBV) exposure and LBP. Bus design may be an important factor in determining the WBV exposure a bus driver receives. The purpose of this study was to determine whether differences exist in WBV exposures between two buses commonly used in long urban commuter routes: a high-floor coach and a low-floor city bus. Each bus was driven over a standardized test route which included four road types: a newer smooth freeway, a rougher old freeway, a city street segment...
Exposure of suspended cabin tractor semi trailer drivers exceeds the upper limit for an 8-h work day
This paper presents a study on whole body vibration analysis for drivers of tractor semitrailers. The tractor semitrailer, namely, a suspended cabin tractor semitrailer was considered for the present investigation. The important process parameters such as different speeds, different road surfaces and different loaded conditions with driver seat interface acceleration in X- longitudinal, Y transverse and Z-vertical axes were tested. The average running weighted root mean square accelerations obtained after conducting the experimental work were between 0.6265 and 1.5594 m/s2 at the driver seat interface...
Vibrations, exiguïté, faible marge de manoeuvre
Comment améliorer le poste de conduite du métro de Montréal? Ce document est destiné aux intervenants en santé et en sécurité du travail, aux ergonomes, aux ingénieurs et à toute personne concernée par l'amélioration d'un poste de travail dans un contexte de faible marge de manoeuvre. Il décrit sommairement tant la démarche technique que la collaboration qui ont permis d'améliorer le poste de conduite du métro de Montréal dont le siège, l'espace restreint et les...
The bi-sound signal to be mandatory for track work (IFA): the perceptibility of the signals have been tested under working noise conditions
Warning signal generators are used at points where track work is being carried out in order to warn workers of approaching trains on neighbour-ing lines, electroacoustic signal generators are generally employed. Harmonization of the warning signals would simplify instruction at the work site. In addition, the signal generators fitted on track-laying machines would not repeatedly have to be set to whichever warning signal is emitted by the signalling devices on the track being worked on. In order to determine the perceptibility of the signals under working noise conditions, hearing tests were conducted...
Professional driving and prolapsed lumbar intervertebral disc diagnosed by magnetic resonance imaging
Objectives The aim of this study was to investigate whether whole-body vibration (WBV) is associated with prolapsed lumbar intervertebral disc (PID) and nerve root entrapment among patients with low-back pain (LBP) undergoing magnetic resonance imaging (MRI). Methods A consecutive series of patients referred for lumbar MRI because of LBP were compared with controls X-rayed for other reasons. Subjects were questioned about occupational activities loading the spine, psychosocial factors, driving, personal characteristics, mental health, and certain beliefs about LBP. Exposure to WBV was assessed...
Vibrations au corps entier : Les conducteurs de transpalettes électriques se portent mieux
Dans le cadre des travaux du Réseau prévention sur la limitation des vibrations au poste de travail, l’INRS a mené une étude portant sur les transpalettes électriques à conducteur porté. Une problématique que certaines entreprises prennent également en compte lors de l’acquisition de transpalettes. Le niveau de vibrations subies par le cariste dépend d’abord de l’engin qu’il conduit, mais également de l’état des sols, de sa posture, de sa façon de conduire. Source : Travail...
Surveys suggest that transport workers are more exposed to vibrations than the average working population.
European workers in transport over land and through pipelines seem also to be more exposed to vibrations from tools and machinery than the average working population. Several studies demonstrate the detrimental consequences of sustained sitting and being exposed to whole body vibration: exposure to vibrations may lead to back disorders. Based on the information available on heavy machines, the significance of the seat is important when steps to reduce full-body vibrations are taken. Full body vibration, for example caused by the driver’s cabin, may also affect the vision, coordination and...
Une étude de l’INRS passe les transpalettes au crible
Le niveau vibratoire élevé auquel les conducteurs de transpalettes électriques sont soumis impose la mise en place d’actions de prévention. Tel est le constat de l’INRS à la suite d’une étude de comportement de 6 TEP (transpalettes électriques à conducteur porté). L es conducteurs de charriots sont plus souvent que les autres salariés soumis à des risques de lombalgies et autres mots de dos, de sciatiques, de radiculalgies crurales, de microtraumatismes de la colonne vertébrale… L’étude...
Whole-body vibration and ergonomics of driving occupations
Ports industry Back disorders are the most common form of ill health at work. The exact cause of back pain is often unclear but back pain is more common in jobs that involve driving, especially over long distances or over rough ground. Driving exposes the vehicle’s occupants to whole-body vibration that may include the shocks and jolts that are believed to increase the likelihood of injury or pain in the lower back. However drivers may also be exposed to other risk factors for lower-back pain such as poor posture while driving and manual handling while loading and unloading goods. The Health...

Développement d’un prototype de siège pour opérateur de métro dans un contexte où l’espace est très restreint
Cette étude porte sur le développement d'un prototype de siège d'opérateur de métro permettant d'atténuer les vibrations et d'améliorer le confort, tout en convenant à l'espace très restreint de la loge de conduite. Le siège actuellement utilisé (strapontin) et conçu il y a une trentaine d'années, s'avère insatisfaisant : il est de confection rudimentaire et amplifie les vibrations. Cette étude fait suite à l'analyse ergonomique et vibratoire du poste d'opérateur...
Effectiveness of an occupational health intervention program to reduce whole body vibration exposure
Background An effective intervention program aiming to reduce whole body vibration (WBV) exposure at work will reduce the number of low back complaints in the near future. Methods An evaluation study with a controlled pretest–post-test design. Nine companies and 126 drivers were included in the study. Cluster randomization on company level divided the drivers and their employers in an intervention group and a ‘‘care-as-usual'' group. At baseline (T0) and intervention program was implemented and evaluated after 7 months (T1). The main outcome measure was WBVexposure. Process...
