In jzeyl/AcousticCalcs: Common calculations in acoustics and audiometry

Note this is a work in progress - several functions may be incomplete

AcousticCalcs

The AcoustiCalcs package is a set of convenience functions for common calculations in acoustics and audiometry.

Installation:

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

Functions

|Category|function|description| |-----|-----|-----| |Unit conversion|hztocents()| convert a frequency interval to cents, semitones, and octaves |Sound propagation|onsettimediff()| Plot the time difference and phase angle differences between a sound wave passing through two recievers. 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| |Audiogram metrics| audiogramslice() | Get high and low frequency hearing limits, best sensitivity, and best frqeuency from an audiogram for a given SPL level. ||humanaudiogram()| data with human audiogram for reference
