Talk:Stokes's law of sound attenuation

Reference needed

It would be nice to provide the reference for: "More recent studies have established..." JeromeB (talk) 09:12, 21 October 2008 (UTC)

Liquids or fluids in general?

This article uses the word "liquids" several times when it should be "fluids". Am I missing something? (The term "fluid" includes gases as well as liquids). TundraGreen (talk) 03:07, 9 September 2009 (UTC)

Revision needed

The original article read as if it had been copied out of some larger article or book, possibly dealing specifically with ultrasound propagation in water. Some problems remain, e.g. the claim of a terahertz relaxation frequency does not specify the fluid. Also, I guessed that the attenuation refers to amplitude; could it be energy (amplitude squared) instead?

Change of units

I removed the following paragraph since it seemed to be a comment/request to editors, rather than article material. Perhaps the "other units" refers to the left-hand side $2(\alpha V/\omega )^{2}$ in the high-frequency formula?

"It is convenient to convert attenuation into other units, by normalizing attenuation with respect to frequency, because the attenuation typically increases rapidly with frequency. These new units make more adequate presentation of attenuation within a wide frequency range. It is seen that attenuation of the Newtonian fluid, presented in these units, becomes a linear function of frequency."
