Comparative study of noise levels between two architectural designs in Intensive Care Unit

Abstract

In an earlier study done by the first author and team, the average noise levels in a mixed medical-surgical intensive care unit (ICU) ranged from 41dB to 58dB. In this study we attempted to study the impact of partitions between patient beds (effectively single patient cubicles) on the noise levels in the ICU. As per results of our study, introduction of simple, cost effective, non-movable, permanent partitions (not curtains) between patient beds (or presence of cubicles) caused a significant reduction in noise levels. This reduction in noise levels was seen across 24 hours (average noise range from 38 to 52dB).
