Noise Levels and Flight Profiles of Eight Helicopters Using Proposed International Certification Procedures

Abstract

This document reports the findings of helicopter noise tests conducted at the FAA National Aviation Facility Experimental Center (nafec), located in Atlantic City, New Jersey. The tests were conducted with the following objectives: first, determine the feasibility of a takeoff procedure for helicopter noise certification; second, establish a data base of helicopter noise levels to be used in defining noise standards; third, acquire helicopter acoustical spectral data for a variety of acoustical angles for use in the FAA Integrated Noise Model. This report addresses the first two objectives.
