Help absorption
Compute heading, field intensity and inclination angle
Syntax
a = absorption(f,T,d) % Matlab & Octave a <- absorption(f, T, d) # R
Description
Absorption coefficient for sound in seawater.
Inputs
| Input var | Description | Default value |
|---|---|---|
| f | is frequency in Hz | Hz |
| T | is temperature, degrees C | Celsius |
| d | is depth in meters | m |
Outputs
| Output var | Description | Units |
|---|---|---|
| a | is the sound absorption in dB per meter. | db/m |
Notes & assumptions
- Input arguments can be scalars, or a mixture of vectors and scalars as long as each argument is either a vector of length nx1 (with n being the same for all vector arguments) or a scalar.
- After Kinsler and Frey pp. 159-160
Example
Matlab & Octave
absorption(140e3,13,10) a = 0.0435 % dB
R
absorption(140e3, 13, 10) a = 0.04354982 # dB
