I think the distinction between acoustic waves, stronger waves and shock waves justifies this topic having it's own page. Paulgush 09:09, 4 March 2007 (UTC)[reply]

Echo section

How come there is a section on echoes in this article? As far as I know, it belongs in a separate article? --JB Adder | Talk 10:55, 6 October 2008 (UTC)[reply]

Possible Error

I think the below statement under the "Phase" title is incorrect. They seem to be directly proportinate in the equation.

"From this equation it can be seen that when pressure is at its maximum, displacement reaches zero."

Acoustic wave only longitudinal?

The article describes acoustic waves as being longitudinal. However this is not true for solids and thus not true in general. Please clarify! — Preceding unsigned comment added by Usman.exe (talk • contribs) 05:28, 3 January 2017 (UTC)[reply]

Possible contradiction related to the reflection coefficient

I think there may be a contradiction with the definition of the reflection coefficient $R$ . In the Reflection section, it is defined as a ratio of acoustic intensities (energies), but I think that in the Absorption section $R$ is used as a ratio between pressures (amplitude) in the equation $\alpha =1-R^{2}$ . I think the equation should be $\alpha =1-R$ or use a new symbol and define it as a ratio of pressures; some papers use $\beta$ ^[1] but I am not sure if other symbols are also used. — Preceding unsigned comment added by David93zgz (talk • contribs) 07:04, 17 September 2019 (UTC)[reply]
