Quantities and Procedures for Description and Measurement of Environmental Sound - Part 6: Methods for Estimating of Awakenings Associated with Outdoor Noise Events Heard in Homes

Provides a method to predict sleep disturbance in terms of percent awakenings or numbers of people awakened associated with noise levels in terms of indoor A-weighted sound exposure level (ASEL). Developed from field studies of behavioral awakening primarily in homes near areas of routine jet aircraft takeoff and landing operations, railroads, roads, and highways. The database used in derivation of the method consists of about 10,000 subject-nights of observations in a variety of communities.
