“…It is predominantly noted in the highfrequency region, with typical notch at 4-6 kHz. 57 In this study, noise-exposed workers had a significantly higher mean threshold of hearing compared to their referent control, and more than three quarters had NIHL. Cells in the human body depend on a proper supply of oxygen and nutrients in order to maintain their functions and such supply depends on the functional and structural integrity of the heart and blood vessels.…”

Background: The gene-environment interaction in the pathogenesis of hypertension has not been extensively studied in occupational noise. Objectives: The aim of this study was to determine the relationship between noise and hypertension in Egyptian workers, the interaction of angiotensin-converting enzyme (ACE) gene polymorphisms as modifiers, and the possible relationship between noise hearing impairment and hypertension. Methods: Study subjects were divided into two groups depending on noise exposure level. The control group (n5161) was exposed to noise intensity ,85 dB and the exposed group (n5217) was exposed to noise intensity §85 dB. A polymerase chain reaction was used to differentiate the various genotypes of ACE insertion/deletion (I/D) and ACE G2350A. Results: Noise significantly increased the likelihood of hypertension. Carriers of the genotypes AG, GG, and DD were vulnerable to hypertension on noise exposure. No association between hypertension and hearing impairment or noise-induced hearing loss (NIHL) was found. Conclusion: Our results support the association between ACE gene polymorphisms and occurrence of hypertension in noise-exposed workers.

Background: Hearing impairment (HI), resulting from noise exposure, can be incapacitating and irreversible. Objectives: The present study aimed to determine the relationship between noise exposure and HI among workers and employees in a spinning industry. Methods: This cross sectional study was conducted on 489 workers in a spinning industry in Iran during 2015. The census method was applied for the purpose of sampling. The hearing threshold of each ear was determined during work shifts, using Madsen audiometric device. HI was calculated, based on the guidelines by the American Medical Association (AMA). The effects of different variables on HI were assessed via regression analysis.

“…[12] A review on noise-induced hearing loss in Easter European States has also been published recently. [13] Although similar studies do not exist for every country, it is plausible to assume that in an enormous economic area such as the Americas, which includes Latin America, the Caribbean, Canada, and the US, work environments with high noise levels are common, and each one represents an important risk to the auditory health of the workers.…”

The workplace contributes significantly to the total dose of daily noise to which a person is subjected. Therefore, millions of people around the world are exposed to potentially dangerous noise levels and consequently, there is an urgent, global need for legislation to adequately protect the auditory health of workers. Occupational noise legislation has been adopted in many of the countries with different degrees of comprehensiveness and varying levels of sophistication. This paper presents a global view of current legislation on occupational noise in the 22 countries that make up the Americas, that is, Latin America, Canada, and the United States. Upon analysis of the legislation, there are notable differences among countries in the defined values for permissible exposure limit (PEL) and exchange rate. Of the countries that have regulations, the majority (81%) use a PEL of 85 dBA. A PEL of 85 dBA and the 3-dB exchange rate are currently used by 32% of the nations in the Americas. Most nations limit impulsive noise exposure to a peak unweighted sound pressure level of 140 dB (or dBC), while a few use slightly lower limits. However, 27% of the countries in the region still have not established regulations with respect to permissible noise levels and exchange rates. This fact is leaving millions of workers in the Americas unprotected against occupational noise. Provide an overview and analysis of the current legislation on occupational noise in the 22 countries that make up the Americas. The information on legislation, regulations, and standards discussed in this paper were obtained directly from official government sources in each country, the International Labour Organization database, or through various colleagues in each country. (1) There are notable differences among countries in the defined values for PEL and exchange rate. (2) Of the countries that have regulations, the majority (81%) use a PEL of 85 dBA. A PEL of 85 dBA and the 3-dB exchange rate are currently used by 32% of the nations in the Americas. (3) Most nations limit impulsive noise exposure to a peak unweighted sound pressure level of 140 dB (or dBC), while a few use slightly lower limits. (4) 27% of the countries in the region still have not established regulations with respect to permissible noise levels and exchange rates. (5) Millions of workers in the Americas are unprotected against occupational noise.
