This paper first reviews the impact of noise on patients sleep in ICUs. Five previous studies have demonstrated such impacts whereas six other studies have shown other factors to be more important. Staff conversation and alarms are generally regarded as the most disturbing noises for patients sleep in ICUs. Most research in this area has focused purely on noise level but work has been very limited on the relationships between sleep quality and other acoustic parameters including spectrum and reverberation time. Sound-absorbing treatment is a relatively effective noise reduction strategy whereas sound masking appears to be the most effective technique for improving sleep. For future research there should be close collaboration between medical researchers and acousticians. Introduction Noise defined as unwanted sounds could affect people both psychologically and physiologically 1 with reported negative effects including cardiovascular stimulation hearing loss increased gastric secretion pituitary and adrenal gland stimulation suppression of the immune response to infection as well as female reproduction and fertility 2-7 . The World Health Organization WHO recommended that noise levels inside hospital wards should not .
