WebNoise reception limits Noise reception limits have impact on spatial planning, current residents, infra manager and the train operator. Without noise measures, nightly reception levels will be above 40 dB up to 1 000 m or more from the busy railway lines. Levels above 55 dB are found up to 500 m. Reduction of reception levels to 55 dB means WebNoise Reduction Design Goal - The optimum desired dB(A) noise reduction (insertion loss) determined from calculating the difference between future build noise levels with abatement to future build noise levels without abatement. The FDOT has selected 7 dB(A) as the Noise Reduction Design Goal for one (1) or more benefited receptors.
