Would be good to have a table (or functions) to extract acoustic parameters of biological media that are relevant for biomedical ultrasound. See for example: - http://www.k-wave.org/documentation/waterAbsorption.php - http://www.k-wave.org/documentation/waterNonlinearity.php - http://www.k-wave.org/documentation/waterSoundSpeed.php - http://www.k-wave.org/documentation/waterDensity.php
