Noise is one of the most common hazards to which workers are exposed. In addition to occupational exposure, environmental noise, such as road traffic and airplane noise, is prevalent in everyday life. Noise exposure can damage auditory sensory cells in the cochlea, leading to hearing loss, as the hair cells in the inner ear do not regenerate. Moreover, differences in the extent of damage to the inner and outer hair cells can cause an imbalance in the auditory system, resulting in tinnitus, which negatively impacts quality of life.Aside from its impact on hearing, noise is also known to have health effects on the autonomic nervous and endocrine systems. It can alter blood pressure levels, heart rate, and lipid and blood sugar concentrations, which are associated with cardiovascular disease. Studies have also reported disturbances in sleep and cognition, changes in hormonal and immune markers, and gastric motility disorders. Traditionally, most research has focused on the auditory effects of noise, with limited studies analyzing its non-auditory effects. The authors of this paper investigated the non-auditory health effects of noise through three included studies. Firstly, a systematic literature review was conducted on the non-auditory effects of noise exposure. Secondly, the authors examined and analyzed environmental diseases (such as allergic diseases) and immune diseases (such as autoimmune diseases) to investigate the impact of noise on the immune system.The findings indicated that noise exposure not only affects hearing but also has health effects on various other bodily systems, including the circulatory, nervous, immune, endocrine, gastrointestinal, and respiratory systems. Noise exposure at night was associated with environmental diseases, while exposure during the day and night was linked to the development of immune diseases.To protect the health of workers who are occupationally exposed to noise and residents of environmentally vulnerable areas with high noise exposure, more attention and research is needed on the non-auditory health effects of noise exposure, and measures to reduce noise should be taken.
