Why should researchers review journal articles for free when access to journal articles is not free?

Often researchers get articles to review and they are paid nothing. The same publisher charge for accessing the journal articles. Doesn't it seems nonsense? Expecting your view in this regard.

Presumably you mean what is the acoustic attenuation for different grain size, but do you mean for propagation through suspended sediments or for interaction with the seabed? Either way there are several formulae in the text books for attenuation or backscatter as a function of acoustic frequency and grain size distribution.

Generally, scattering will increase with grain size increase. This may cause more attenuation in burst signals.
