In jzeyl/acalculator: Convenience Calculations in Acoustics and Audiometry

acalculator

Set of R functions for common calculations in acoustics and audiometry

Installation:

library(devtools)
devtools::install_github("jzeyl/acalculator", force = TRUE)

Functions

Unit conversions

convert() – convert between Pa, uPa, dynes per cm squared, and ubar. Input the value and the units to convert from and to

angular() Convert frequency to angular frequency

Sound propagation

timediff() – compute the time difference and phase angle differences between a sound wave, give input: frequency, distance between sensors, speed of sound output: a list containing the two sound waves, time difference, and phase difference, an oscillogram plot of the wave if plot = TRUE

dopplershift() – input the speeds of sound source and receiver, and the speed of sound, and direction of movement between sources Output: shifted frequency

pressure_transmissionloss()– input the distance, level of the sound source. Can be converted for raw values or dB. Simply 1/r, spherical spreading. Output: get the amount of (1) transmission loss and (2) new sound level at new location
