The influence of increased motive power and airspeed on noise levels within 163 fixed- and rotary-wing aircraft is depicted in 9 noise-exposure envelopes. Increased power and airspeed resulted in increments in cockpit noise in all of these aircraft groups. Changes in acoustic spectra and speech interference are illustrated and described. (Author)
