Context: Sound pollution is a common problem in intensive care units (ICUs) with unfavorable consequences. Aims: The aim of the current study was to determine the effect of staff training on the amount of sound pollution in the ICU. Setting and Design: This quasi-experimental study was conducted in the ICU of Rouhani Hospital in Babol. Materials and Methods: Level of equivalent (leq) sound was measured in three work shifts for 2 weeks, before and after training, in 2 workdays and a holiday, using a systematic network stationing method. The sample size was determined based on the days of measurement, work-shift, and measuring stations (6 × 3 × 10 = 180). Indirect training was performed. A 2-week opportunity was given to study materials. Statistical Analysis Used: Data were analyzed using paired t-test and RMANOVA. Results: Following the training, the mean leq in all stations (ten stations) decreased from 67.21 to 62.11 dB (P = 0.002). Conclusion: Although the amount of sound pollution decreased significantly after training, it was still higher than standard. To achieve the desired level of sound, continuous monitoring of sound at intervals of 6 months, along with structural engineering and equipment, is suggested.
