Measurements of noise from aircraft level flyovers are presented in the form of effective perceived noise level (EPNL) as a function of slant range at the closest point of approach. Seventeen aircraft were investigated (various military, business jets, and general aviation types) and the effort involved acquisition of acoustical, meteorological, aircraft tracking, and aircraft operational data. Microphones were located near the ground in an array normal to the flight track. (Author)
