Comparing monetary noise values based on annoyance to values based on noise levels

Determining the monetary impact of transportation noise is increasingly important. Several methods exist to estimate the monetary values. In this paper two different methods are compared; monetary values based on noise levels and annoyance data. It is demonstrated that using published data on values based on annoyance gives lower values than what is the case for noise levels. Using annoyance also puts a limit on how fast the noise valuation increases as the sound level/annoyance increases. All comparisons utilizes the standard curves that predict the number of annoyed as a function of the day-evening-night noise level (Lden).
