Available in PDF, EPUB and Kindle. Book excerpt: Calculation procedures to describe airplane noise during takeoff and approach have been programmed for batch operation on a large digital computer. Three routines are included. The first normalizes far-field noise spectra to reference conditions and then determines spectra at various distances from the airplane, for airport elevations between sea level and 6000 feet and ambient temperatures between 30 deg F and 100 deg F. Overall sound pressure levels, A-weighted noise levels, perceived noise levels, and effective perceived noise levels are calculated. The second routine uses aerodynamic and engine thrust data to produce takeoff and approach flight path description. Volume 2 includes L-1011-1 noise propagation and airplane performance and samples of contours.

The first normalizes far-field noise spectra to reference conditions and then determines spectra at various distances from the airplane, for airport elevations between sea level and 6000 feet and ambient temperatures between 30 deg F and 100 deg F. Overall sound pressure levels, A-weighted noise levels, perceived noise levels, and effective perceived noise levels are calculated. The second routine uses aerodynamic and engine thrust data to produce takeoff and approach flight path description. The basic takeoff is at equivalent airspeed, with thrust reduction or acceleration option after gear-up. The approach is along any constant glide slope between 3 and 6 degrees at constant airspeed, with a two-segment option. The last routine combines noise propagation and flight path information to produce constant noise contour footprints. The program has been exercised on Lockheed L-1011-1 Tristar/Rolls-Royce RB. 211-22 data, providing results in EPNdB and dBA.

Book excerpt: Acoustic data acquisition and reduction systems are discussed together with analytical procedures used to derive noise characteristics of a series of Boeing aircraft types. Noise data are presented in EPNdB and dB(A) units, from takeoff to low approach thrust and for aircraft altitudes from 200 to 12,000 feet. Areas of possible data deficiency are identified and 90% confidence limits established where possible. A flight test program is proposed with the objectives of improving data accuracy and establishing confidence limits over a wide range of operating conditions.

Book excerpt: Technical data are presented for graphically determining takeoff, cutback, and approach performance and noise under the flightpath for various Boeing Model 737 aircraft currently in operation. Data are included for all certified flap positions and cover operations from airports from sea level to 6000 ft altitude at temperatures from 30 to 100F with winds from -10 to +30 kn over the entire operational weight range. Noise data are shown for units to EPNdB and dB(A) from takeoff to low approach thrust and for aircraft altitudes between 200 to 12,000 ft.
