Calculates the absorption coefficient for sound in seawater

absorption(f, T, d)

Arguments

f	frequency in Hz
T	temperature in degrees C
d	depth in meters

Value

The sound absorption in dB per metre.

Note

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.
