“…At least one in ten working-age American individuals suffers from a loss of hearing that is associated with exposure to loud sound, either from a work environment or through recreational activities 3 . Traumatic injury, such as injury caused by exposure to an explosion or to the firing of a gun, can lead to sudden hearing loss; sometimes this hearing loss is accompanied by the perception of a constant ringing noise (a condition known as tinnitus).…”

Hearing loss is the most common form of sensory impairment in humans and affects more than 40 million people in the United States alone. No drug-based therapy has been approved by the Food and Drug Administration, and treatment mostly relies on devices such as hearing aids and cochlear implants. Over recent years, more than 100 genetic loci have been linked to hearing loss and many of the affected genes have been identified. This understanding of the genetic pathways that regulate auditory function has revealed new targets for pharmacological treatment of the disease. Moreover, approaches that are based on stem cells and gene therapy, which may have the potential to restore or maintain auditory function, are beginning to emerge.

“…It is exceeding the safety limit noise exposure that stated by WHO (85 dB). 6,13 this is can be huge risk for machinist and his assistant who working on it for health impairment especially for hearing dysfunction. Furthermore, all the subject ( 100%) did not apply noise protection device while they worked, it is added more risk for NIHL incident on machinists and his assistant.…”

“…Noise at certain levels can be harmful to health, which cause auditory disorders as deafness and tinnitus, as well as non-auditory disorders such as impaired concentration, communication and socialization disorders, sleep disorders, fatigue, stress, hypertension, disorientation, and decreased productivity. [1][2][3][4][5][6] The incidence of hearing loss induced by noise (NIHL) and other subjective complaints are high, especially in populations which exposed to high enough noise, especially noise associated with the work environment 7 , such as machinist and assistant machinist who work above a noisy locomotive. Factors that affect the noise induced hearing loss are the intensity, frequency, and duration of noise exposure and also age, gender, individual tolerance, and the application of ear protection devise.…”

Abstract. Noise at certain levels at long intervals, will be harmful to health, resulting in auditory and non-auditory impairment. This study is aimed to determine the extended noise exposure induce health impairment in machinist. This analytic study was involved 52 machinist there were chosen as samples using non-probability sampling technique with consecutive sampling method, intensity measurement was done using sound level meter on the locomotive. Interviews were done on the subjects about work length and subjective health complaints. The data were analyzed using Chi square to determine the relationship between the two variables. The noise intensity in the locomotives ranged from 70.9-107.1 dB. The proportion of subjects with work length of <10 years and ≥10 years were 42.9% and 57.1% consecutively. The proportion of hearing loss 2(3, 3%) of machinists whose work less than 10 year, 4 (7, 7%) of machinists whose work between 10 to 19 years, and 5(9.6%) of machinist whose works over 10 year, p-value 0.041 (p <0.05). The proportion of subjects with subjective health complaints are communication difficulties (24.5%), temporary tinnitus (36.7%), permanent tinnitus (0%), temporary hearing loss (20.4%), permanent hearing loss (0%), emotional disturbances (6.1%), and hypertension (0%). Statistical analysis between work length and hearing loss showed significant association, but between work length and health complaints showed an unsignificant association (p-value >0.05)

“…Presumably, the higher the level of worker's awareness about the importance of hearing prevention, provided by the years accumulated in the manufacturing unit HPP, the higher the importance given to the aspects of the hearing protector. Other studies indicate the importance of awareness about the hearing loss prevention, contributing thus for a better assessment and acceptance of hearing protectors by workers who are exposed to intense noise (9,12,17,(27)(28)(29) . With regard to the assessment of aspects regarding hearing protectors used by workers (Questionnaire 2), it has been seen, in general, that the best-assessed aspect was hearing protector placement (considered as the closest to judging as "easy placing," according to the questionnaire scale).…”

PURPOSE: To evaluate and compare the workers' perception of comfort and use aspects regarding two types of hearing protectors (shell and earplug), in three units from a lumbering company, with different implantation times for Hearing Preservation Programs.METHODS: This is a cross-sectional study comparing 440 workers' perception of hearing protectors, from three companies in Paraná State (Brazil), with different times for Hearing Preservation Programs. Two closed questionnaires were applied (9 and 10 questions, respectively), with a scale of answers varying from 1 to 5 (Likert's scale) regarding the perception of the comfort of hearing protectors. Then, audiometry results were analyzed.RESULTS: About 17.5% presented audiogram examinations with alterations. With regard to the questionnaire about the comfort perception, the importance of noise attenuation (mean of 4.25) was the most relevant aspect, followed by communication possibility (mean of 4.15). In the protector assessment, Unit A with more Hearing Preservation Program time presented better scores for both the worker's perception of important aspects regarding hearing protector and for the assessment of the used hearing protector. There was a significant difference on communication difficulty with the use of a hearing protector among workers with normal and altered audiograms (p=0.0371). With regard to the global comfort in the comparison of workers using the shell-type hearing protector with those using insert-type hearing protectors, there was no difference (p=0.2264), irrespective of the type of the unit.CONCLUSION: In general, the unit workers presented a good perception of the important aspects about the hearing protection use of both types of hearing protectors.
