Abstract

High noise levels in hospitals are often linked to various negative effects on patient outcome and work performance of clinical staff. Despite growing research attention on the adverse acoustic conditions in healthcare environments, few studies offer on-site surveys collected for a relatively long period with a clear description of the measurement protocol, and furthermore, the sources of noise in hospitals are not well documented in the literature. In the current study, the soundscape of an ICU (intensive care unit) room was analysed based on a ~3-day calibrated audio recording, from which acoustic parameters were obtained off-line. In addition, a selected 24-hour recording was annotated, which enabled a source-specific analysis, excluding the patient-generated/-involved contributions. The results showed that the acoustic energy of the noise in this ICU room was attributed to speech and other activities by staff (57%), alarms (30%) and the operational noise of medical devices (13%). In addition, the analysis of the number of loudness peaks showed similar but more uneven proportions: staff (94%), alarm (5%) and device noise (1%). The current study suggests that, to a considerable extent, the noise in ICUs may be attributed to potentially modifiable factors, e.g., staff’s speech and activities.
