Calculate the speed of sound in a medium

Given sufficient parameters (i.e. wavelength and frequency, bulk modulus and density) this function calculates the speed of sound.

Usage

soundSpeed(
  medium = NULL,
  method = NULL,
  wl = NULL,
  f = NULL,
  bulkModulus = NULL,
  density = NULL,
  ...
)

Arguments

medium

Propagation medium (e.g. "air"), or "all" to return a list of all available media.

method

Use a specific method to calculate the speed of sound (see Details).

wl

Wavelength

f

Frequency

bulkModulus

Bulk modulus

density

Density

...

Additional parameters passed to the method.

Details

The speed of sound can be calculated using the following methods:

• cramer Uses the method described in cramer1993;textualsonicscrewdriver. Additional parameters are:

  • temp Temperature

  • temp.unit Temperature unit

  • pressure Pressure

  • pressure.unit Pressure unit

  • RH Relative humidity

  • MoleFracCO2 Mole fraction of CO2

• seewave Delegates the calculation of the speed of sound in air to the package seewave seewave2008sonicscrewdriver. This calculation is . performed as \(\text{speed} = 331.4 + 0.6 \times \text{temp}\). Additional parameters are:

  • temp Temperature
