Frequency dependent attenuation rate problem
I am no expert but this part seems incorrect.

"Acoustic attenuation in water is frequency-squared dependent, namely $$\eta=2$$. Acoustic attenuation in many metals and crystalline materials is frequency-independent, namely $$\eta=1$$. "

$$\eta=1$$ means the characteristic length is $$1/\alpha_0\omega$$, yet the source (which seems to have incorrect syntax as well) claims it's frequency independent. Someone who knows this check if the statement is valid. 59.115.129.173 (talk) 18:58, 27 February 2024 (UTC)
