Acoustics and psychosocial environment in intensive coronary care.

Author information

  • 1National Institute for Psychosocial Factors and Health, Stockholm, Sweden.



Stress, strain, and fatigue at the workplace have previously not been studied in relation to acoustic conditions.


To examine the influence of different acoustic conditions on the work environment and the staff in a coronary critical care unit (CCU).


Psychosocial work environment data from start and end of each individual shift were obtained from three shifts (morning, afternoon, and night) for a one-week baseline period and for two four-week periods during which either sound reflecting or sound absorbing tiles were installed.


Reverberation times and speech intelligibility improved during the study period when the ceiling tiles were changed from sound reflecting tiles to sound absorbing ones of identical appearance. Improved acoustics positively affected the work environment; the afternoon shift staff experienced significantly lower work demands and reported less pressure and strain.


Important gains in the psychosocial work environment of healthcare can be achieved by improving room acoustics. The study points to the importance of further research on possible effects of acoustics in healthcare on staff turnover, quality of patient care, and medical errors.
