VEHICLE NOISE DETECTABILITY CALCULATOR

摘要

A system for determining the detectability of a fleet of vehicles by a listener at a target site. The system receives as input at least the number of vehicles, a selection of a noise signature for each vehicle, and a distance to the target. The system may then estimate noise pressure level for the fleet along the estimated distance from the given location to the target site based on the noise signature associated with each vehicle and display a graph showing the noise pressure level vs. distance from the given location to the target site. In an embodiment, the system may estimate the background noise level at the target site and subtract this from the noise pressure level of the fleet at the target site to determine an expected noise level above background noise at the target site.
