Adverse cardiovascular effects occur from chronic exposure to noise due to the sympathetic nervous system's inability to habituate. The sympathetic nervous system maintains lighter stages of sleep when the body is exposed to noise, which does not allow blood pressure to follow the normal rise and fall cycle of an undisturbed circadian rhythm ...
Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health , as sustained exposure can cause permanent hearing damage.
Occupational noise exposure is the main risk factor for work-related hearing loss. One study examined hearing test results obtained between 2000 and 2008 for workers ages 18–65 who had a higher occupational noise exposure than the average worker. [153] Of the sample taken, 18% of the workers had hearing loss.
Occupational hearing loss (OHL) is hearing loss that occurs as a result of occupational hazards, such as excessive noise and ototoxic chemicals. Noise is a common workplace hazard, and recognized as the risk factor for noise-induced hearing loss and tinnitus but it is not the only risk factor that can result in a work-related hearing loss.

Noise and ageing are the primary causes of presbycusis, or age-related hearing loss, the most common kind of hearing loss in industrial society. [10] [citation needed] The dangers of environmental and occupational noise exposure are widely recognized. Numerous national and international organizations have established standards for safe levels ...
Annoyance implies a negative factor on an individual's well-being and comfort. Its effects may include physiological responses, central nervous system reactions, and biochemical changes. [1] Physiological reactions to sound annoyance include increased heart rate and increased blood pressure which, among others, may lead to hypertension.
During the exposure, most people experience discomfort and pain.After the exposure, some people might report shock, nausea and anxiety or depression. [2] Headache, fatigue, hypersensitivity to loud noise and tinnitus may continue for days, weeks or indefinitely. [3]
Occupational epidemiology is a subdiscipline of epidemiology that focuses on investigations of workers and the workplace. [1] [2] Occupational epidemiologic studies examine health outcomes among workers, and their potential association with conditions in the workplace including noise, chemicals, heat, or radiation, or work organization such as schedules.
