This report provides effective perceived noise level (EPNL) data for civil aircraft in a form useful for noise exposure forecast (NEF) calculations. The EPNL noise data are presented in graphical and tabular form; the report also summarizes the data sources and technical analyses used in developing the noise data. A companion report presents sound exposure level (SEL) data for use in day-night level (Ldn) calculations. Noise data are included for all major current U.S. civil transport and business jet aircraft and for most general aviation aircraft. Data are also provided for possible retrofit of low bypass ratio (LBPR) turbofan transport aircraft with acoustically lined nacelles.
