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 $\eta =1$ .^[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)[reply]
