THE MEASUREMENT OF LOCOMOTIVE NOISE AT EXISTING RAILROAD TEST SITES
A study was undertaken to examine the feasibility of accurately measuring the noise from locomotives at existing load cell sites in the absence of sites conforming with U.S. Environmental Protection Agency standards. It was found through measurements at seven typical sites and one conforming load cell test site involving ten locomotives that reasonably accurate measurements were possible for the locomotive operating fully loaded at throttle 8. Errors, when they occurred, were due primarily to sound reflecting off nearby buildings. Measurements with the locomotive in idle were generally difficult because of high background noise at these sites. A passby test procedure was also examined and found to provide reasonably accurate measurement of locomotive noise at throttle 8, full load.
