Statistical Study of Noise Levels in an Adult ICU A Case from India
Journal Title: International Journal of Biomedical Research - Year 2015, Vol 6, Issue 11
Abstract
Objectives: The purpose of this study was to observe and record the levels and sources of noise in an adult ICU. These results and observations are to form the basis of protocols to control noise levels in an ICU. These will also be treated as baseline values for comparison with results obtained in future studies to determine the effectiveness of noise reduction protocols. Methods: Average noise levels were recorded in the adult ICU of S.L. Raheja Hospital (A Fortis Associate) over a period of 10 days and 10 nights. A digital sound meter was used to record the sound levels and an average of 5 readings at the start of every hour was recorded. Along with measurements, physical observation and a literature review of recent noise studies in ICUs was also undertaken. Result: Noise levels in the ICU were found to be higher than the guideline values in accordance with most recent studies. It was observed that the major source of high noise levels was caregivers such as ward boys who tended to speak loudly while doing their duties. During the day, noise levels were higher than at night and noise levels increased sharply during shift changes. Conclusion: Almost 61% of the noise in the ICU was found to be modifiable. In future, on the basis of the results of this study, protocols will be formed and steps will be taken to reduce the modifiable noise to bring down noise levels further to ensure faster recovery and greater patient comfort.
