Distribution of road traffic noise exposure Lday and Lnight in the LifeLines Cohort Study. Medians, 25th, and 75th percentiles are shown in the box, whiskers indicate 5th and 95th percentiles. dB(A) = decibel (A); Lday = A-weighted equivalent noise level over the 12-h day time period from 07:00 to 19:00 h; Lnight = A-weighted equivalent noise level over the 8-h night time period from 23:00 to 07:00 h
