Question

For test purposes, a simple exposure-response function (ERF) that can be called from another variable?

Answer

Use Miedema's ERF for the prevalence of high annoyance as a function of road noise exposure (Lden).

To use this function, include the R code named "ERF_Lden_HA" from this page as follows...

<rcode include="page:Test_variable_C|name:ERF_Lden_HA" >

...and using the input variable "Lden" call the function as follows:

PercentHighlyAnnoyedByRoadNoise <- ERF_Lden_HA(Lden)

Rationale

Dependencies

Formula

- Hide code


ERF_road_Lden_HA <- function(Lden) {
	PercentHighlyAnnoyedByRoadNoise <-
	9.868 * 10^-4  * (Lden - 42)^3 - 1.436 * 10^-2 * (Lden-42)^2 + 0.5118 * (Lden - 42)

	return(PercentHighlyAnnoyedByRoadNoise)
}


# debug ERF_road_Lden_HA(60)
