find_r: Radius calculation

In dayvayen/commspacetime: Modeling Communication Space-Time For Acoustic Species

Description

This function calculates the radius of the sphere or hemisphere of communication. This can then be used in future calculations. It requires an initialized vector to work with–the upper limit of this can be determined by your species' vocalization propoerties.

Usage

find_r(signal, noise, r_vector, absorption = 1, perception = 0)

Arguments

signal	The source level (dB re 20 microPa) of the vocalization.
noise	The ambient noise level (dB re 20 microPa) of the place where the animal is vocalizing.
r_vector	The initialized vector of possible radius values.
absorption	The atmospheric absorption calculated by the absorption.R function. Set to 1 unless otherwise specified.
perception	The detection threshold for your species in question, if known. By default, this is set to zero, which indicates the best possible scenario in which any signal can be perceived if it is above the level of background noise.

Examples

find_r(90, 65, r_vector, absorption = 1, perception)
