Title and Subtitle: Cockpit noise intensity: Fifteen single-engine light aircraft

Report Date: September 1968

Authors: Tobias JV

Abstract: Fifteen of the most popular single-engine general-aviation light aircraft were tested for the noise intensity present during normal cruising operations at 2000, and 10,000 feet MSL (mean sea level). In comparison with currently accepted DRC (damage-risk criterion) curves, the noise levels found even in the quietest plane tested could be damaging. However, a well fitted pair of earplugs should protect against the physiologically damaging noise intensities encountered in this study.
