Calculates the absorption coefficient for sound in seawater

Usage

absorption(freq, temperature, d)

Arguments

freq: frequency in Hz
temperature: 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.
