Abstract

Objective: The study was aimed at determining the efficiency of precautions aimed at noise reduction in an
intensive care environment.
Methods: Noise measurement in the unit was made in two phases. In the first phase, measurements aimed
at determining the unit’s present level of noise were made over three weeks between 01 January 2012 and
01 February 2012. During the month following the first phase measurement; applications aimed at noise
reduction including staff education, physical space arrangement were performed and device alarms were
checked. All nurses working in the intensive care unit where the study was conducted were lectured on
noise and noise reduction. Staff education: The scope of education included topics such as definition of
noise, the effects of noise on the patients and the healthcare staff, medical errors associated with noise, the
applications aimed at noise reduction and their efficiency. All staff using the monitors were told to not
activate unnecessary alarms. physical space arrangement: A room in the unit was rearranged as an area
where the staff could converse with each other without disturbing the patients. In order to alleviate the
disturbance due to the noise produced during the preparation of treatment, the area that previously had
been allotted for treatment was moved away from the patients and isolated by a door. The second phase
including the subsequent three weeks (01 June 2012 and 01 July 2012), control measurements were made.
Results: In this study, the highest recorded noise was staff conversations from the nurses’ station (89 dBA).
The noise levels before and after the precautions aimed at noise reduction were calculated as 67,6 dB-A
and 56 dB-A and the difference between the two levels were statistically significant (p<0.05).
Conclusion: The applications aimed at noise reduction are effective in reducing the noise in intensive care
units.
