Noise levels

Generates rasters describing the daily noise footprint of selected wind farms, as defined in a scenario object.

map_noise(obj = NULL)

Arguments

obj

An object of class narwscenario.

Value

A list containing noise layers for each day, in SpatialGridDataFrame format.

Note

The function relies on a simple propagation model which assumes that transmission loss depends on both log-range and frequency-specific absorption. The model is of the form: TL = b x log10R + a x R, where b = 15 and a = 1.175 by default. The resultant sound pressure level (SPL) from multiple sources is calculated based on the logarithmic addition of sound intensities from each source.
