Evaluating the impact of noise on sleep quality is challenging as it must be measured relative to other factors that may be more or less disruptive to patients sleep. Such factors may be difficult for patients observers and polysomnogram interpreters to identify due to our limited understanding of the causes of sleep disruption in the critically ill as well as the challenges in recording and quantifying sleep stages and sleep fragmentation in the intensive care unit. Furthermore most research in this field has focused on noise level whereas acousticians typically evaluate additional parameters such as noise spectrum and reverberation time. The authors highlight the disparate results and limitations of existing studies including the lack of attention to other acoustic parameters besides sound level and the combined effects of different sleep disturbing factors. In the previous issue of Critical Care the review by Xie and colleagues aims to answer the following questions 1
