Abstract : Eleven of the most popular twin-engine general-aviation light aircraft were tested for the noise intensity present during normal cruising operations at 2000, 6000, and 10000 feet MSL (mean sea level). Although generally quieter than single-engine planes, these aircraft, in comparison with currently accepted DRC (Damage-risk criterion) curves, have noise levels (even in the quietest plane tested) that could be damaging. However, a well fitted pair of earplugs should protect against the physiologically damaging noise intensities encountered in the study. (Author)
