THE IMPACT OF NOISE LEVELS IN HEALTHCARE FACILITIES ON NERVOUS SYSTEM FUNCTION AND WORK PERFORMANCE: A LITERATURE REVIEW

Abstract

This literature review examines the impact of noise levels in healthcare facilities on central nervous system function and the work performance of medical personnel. Based on contemporary scientific evidence, it has been established that noise levels in medical institutions frequently exceed hygienic standards, particularly in intensive care and resuscitation units, where they range from 60 to 80 dB. The findings indicate that elevated noise levels are associated with autonomic nervous system imbalance, increased cortisol secretion, elevated arterial blood pressure, and impaired cognitive functions. The analysis demonstrates that noise represents not only a hygienic but also a clinically significant risk factor, with its effects primarily mediated through the central nervous system. Therefore, the optimization of the acoustic environment in healthcare facilities, through comprehensive hygienic and organizational measures, is a critical scientific and practical priority.
