Abstract

Military jet aircraft are some of the fastest vehicles ever made. Their jet engines exhaust fuel at supersonic speeds and create large amounts of noise. However, this noise is loud enough to cause hearing loss, even with the most advanced levels of hearing protection. In particular, hearing loss is a problem that many military aircraft workers experience. This research is part of a larger project that is analyzing the sound field around these jets in order to address the problem. The purpose of this research was to reconstruct an equivalent sound source for the jet. This modeled sound source is used to calculate the radiated sound field around the jet. An analysis of the sound field allows military officials to make informed decisions about jet protocol and where to place workers during a take-off.
