attenuation: Generate sound intensity attenuation data

Description

This function generates dB data following theoretical spherical attenuation of sound.

Usage

attenuation(lref, dref = 1, dstop, n, plot = TRUE,
xlab = "Distance (m)", ylab = "dB", type = "l", ...)

Value

• If plot is FALSE return a numeric vector with the data generated.
