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
