Project Experience: Noise Exposure Response, Sleep Disturbance

This project’s goal is to understand the impact of aircraft noise on sleep, and to develop models that predict sleep disruption for a given aircraft noise profile.  What is not fully understood is how much aircraft noise impacts sleep in communities around airports, and how impacts due to aircraft noise compare with those due to other things (other noise sources, weight, age, stress, etc.) that are known to affect sleep.  Models that predict the probability of being in different sleep stages given different profiles of night-time noise exposure are being examined, as are models that predict awakenings.  By coupling the resulting sleep disturbance models with noise prediction tools, it will be possible to show, e.g., potential awakening patterns in communities for a wide range of different airport and air traffic scenarios.
