Abstract:Aircraft noise can disrupt sleep and impair recuperation. The most recent US investigation on the effects of aircraft noise on sleep was conducted more than 20 years ago. Since then, traffic patterns and noise levels produced by single aircraft have changed substantially. It is therefore important that field studies be conducted in the U.S. to acquire current data on sleep disturbance relative to varying degrees of noise exposure. To inform the design of a larger national study, a pilot field study was conducted around Atlanta Airport. The primary goal was to assess feasibility of acquiring acoustical and physiological data with no investigator on site and equipment mailed to participants who then applied electrodes and started and stopped measurements each night on their own. We mailed 4080 recruitment questionnaires to randomly selected households exposed to aircraft noise (>/35 dB LAeq.23-07,outdoor). Among the 407 respondents, 34 participated in the unattended five night in-home study. Indoor sound levels were determined via measurement. Arousal from sleep was recorded via a device measuring body movement and electrophysiological heart rate. Self-reported sleep was assessed with morning questionnaires. Several ways to improve data quantity and quality were identified. Overall, the approach was found to be feasible.
