Non-Auditory Effects of Hospital Noise: A Cross-Sectional Study Among Staff Working in A Tertiary Care Hospital in New Delhi, India
Year: 2025
Type: article
Study design: Observational Study
Abstract: Introduction: Hospital noise is associated with non-auditory symptoms such as stress, sleep disturbances, impaired concentration, and headaches among healthcare staff. These are often classified as quality-of-life issues rather than illnesses. This study aims to assess the prevalence of non-auditory effects of noise and their association with hospital noise levels. Methods: A cross-sectional study was conducted among 450 staff members at a 1600-bed tertiary care hospital in New Delhi, India. Noise levels were recorded at 30 locations, and data were collected using a pre-tested questionnaire. Multivariable logistic regression analysis was performed to explore associations between noise levels and symptoms. Results: Sleep disturbance was reported by 75.1% of respondents, vocal fatigue by 73.8%, and impaired concentration by 56.7%. Adjusted analysis revealed significantly higher odds of headache (aOR=2.49, 95% CI: 1.44–4.33), impaired concentration (aOR=2.36, 95% CI: 1.35–4.13), tinnitus (aOR=4.55, 95% CI: 2.36–8.77), and fatigue (aOR=3.14, 95% CI: 1.12–8.77) with noise levels >80 A-weighted decibels(dBA). Conclusions: Non-auditory effects were prevalent in three-fourths of participants, with worse outcomes at noise levels >80 dBA. These findings underscore the need for policies to mitigate hospital noise and protect staff well-being.
