“…Other studies showed a hearing loss in different levels in most of the individuals exposed to noise and who were submitted to tonal audiometry 9,16,17 , which differs from the results found in this research. A justification for such a finding would be the noise level to which this study's participants have been exposed to, that is, maximum levels lower or higher than 85dB (A).…”

“…expands to frequencies 8, 2, 1, 0.5 and 0.25 kHz, which goes against the findings of this research, since Group 1 was exposed to higher levels of sound pressure and underwent longer exposure time (average of 20 years), and presented higher thresholds, albeit within the criteria of normality. A range of studies has revealed hearing loss in the high frequencies, especially with its beginning at 4kHz, with evolution for the circumjacent 6kHz and 3kHz frequencies which, due to its being located in the basal region of the cochlea, is firstly reached by the noise exposure, whether by the differences in the mechanics of the cochlea, whether in the cochlear metabolism or in the cochlear blood supply 1,12,16,17,20,21 . In this study, albeit the hearing loss having not been identified in any of the tested frequencies, the worst thresholds occurred in the 4kHz and 6kHz frequencies.…”

“…Another group of diseases comprises ear diseases, especially deriving from internal factors in the work environment and affecting different professional categories, such as marble, wood, iron and steel and cement factory workers (19) , machine operators, drivers and guards (20) , iron and steel industry, transportation, civil construction, textile and mining workers (21,22) .…”

“…Thus, workers' constant exposure to occupational noise beyond these levels can cause important hearing alterations, such as buzzing, difficulties to understand speech, low hearing levels and hearing-related vertigo (19)(20)(21)(22) . In the dock environment, these can hamper the communication needed to perform activities like surveillance, loading and unloading and load movements.…”

“…(14) As contínuas mudanças que se processam no mundo do trabalho e as distintas características regionais do Brasil têm múltiplos efeitos sobre a saúde e configuram perfis epidemiológicos mutantes na população trabalhadora. Qualquer tentativa de estudar os agravos à saúde do trabalhador no país é sempre parcial, pois não há uma abordagem única que permita uma visão acurada do sistema.…”
