“…Many countries, including Israel, use 85 dBL Aeq,8 h (A-weighted, equivalent continuous sound over an 8-h period) as a cut-off for hazardous occupational noise which requires hearing surveillance for the exposed workers (Arenas and Suter 2014 ; Israel Ministry of Economy and Industry Labour 1984 ). A noise level of 85 dBL Aeq,8 h represents 8% of acceptable excess risk over a 40-year working lifetime (NIOSH 1998 ; Bruce et al 2010 ; Siegel 2019 ).…”

Objectives To investigate the annual rate of NIHL in Israel, a modern economy with relatively low industrial hazardous noise exposure. To review international protocols of hearing surveillance. To recommend an effective, efficient, hearing screening frequency protocol. Methods A historical cohort study was conducted. Audiometric surveillance data from the Jerusalem occupational medicine registry of male employees in various industries from 2006 to 2017 were used. Mean individual annual threshold shifts simulating 1–8 checkup interval years were calculated. Joinpoint regression analysis was used to assess the interval in which the slope of the calculated ATS variability moderates significantly. Results A total of 263 noise-exposed workers and 93 workers in the comparison group produced 1913 audiograms for analysis. Among the noise-exposed workers, using the 1–4 kHz average, threshold shifts stabilized from 3 years onwards at around 1 dB per year in all age groups and 0.83 dB in the stratum younger than 50 years. No enhanced decline was detected in the first years of exposure. Conclusion Although most countries conduct annual hearing surveillance, hearing threshold shifts of noise-exposed workers become more accurate and show less variability when calculated at 3-year checkup intervals onwards than shorter intervals. Since margins of errors of the test method are much larger than the annual shift found, screening schedule that enables each subsequent test to identify a real deterioration in hearing is necessary. Triennial audiometric screening would be a better surveillance frequency for noise-exposed workers younger than 50 years of age in the category of 85–95 dBL Aeq,8 h without other known risk factors.

“…Acute exposure to noise directly causes a number of short-term physiological problems, such as increased blood pressure, increased endocrine secretion, and increased heart rate [12,13]. For this reason, it is necessary to constantly evaluate the noise exposure of the workers to avoid affecting the health of the workers [14]. If the environmental conditions in each workplace are adequate, it improves worker satisfaction, work performance, safety, and health [15].…”

A method is proposed to improve work performance through an adequate design of the manufacturing cell along with optimal environmental conditions to contribute to the well-being of the worker. The methodology used was divided into four stages: the first corresponds to the analysis of operations; the second is the analysis of the effect of the design of the manufacturing cell; the third is the evaluation of environmental conditions such as lighting, noise, and temperature to compare them with the official standard and determine if they meet the permitted levels; and the fourth is to conclude and recommend improvements to the manufacturing cell. The method was applied in a company in the automotive industry, where a change was made from a linear cell distribution to an L-shaped distribution, with a 50% reduction in workforce and an increase in the productive time of the worker of 49%. Also, the environmental conditions of the cell comply with the requirements of official standards.

“…Research stated that at the 85 dBA TWA limit the risk of developing hearing handicap is as much as 8% while at 90 dBA TWA it is as much as 18%. The margin of safety is 75 dBA TWA and the border limit that does not give any increased risk of hearing handicap is 80 dBA [10]. The use of quiet machines is the preferred way while wearing an HPD must be the last approach if all the other methods cannot be applied [11].…”

Machines operators expose to excessive noise in the workplace that may lead to hearing damage. This study investigates construction machine operators noise exposure levels for eight hours or time weighting averages (TWAs), relationship TWA with machine noise emission level, the practices of using hearing protection devices (HPDs) and working in a closed machine cab. Heavy and non-heavy machine operators at five construction sites involved with excavation and piling activities were selected and measured by using dosimeters. 68% of operators were exposed to TWA of 85 dBA and 18% of the operators exceeded the permissible limit. 40% of operators work inside a closed machine cab, 18% wear earplugs and only 16% practiced both. Both operators of heavy machines (except excavators) and dump trucks are exposed to TWA > 90 dBA if they work in open machine cabs. The TWAs were found well correlated (r=0.41) with the machine noise emission, which ranged between 84 dBA to 125 dBA. Furthermore, this study proposes the type of HPD for the operators of typical machine to minimise the risk of hearing loss.
