1. Sea Of Whispers

   Linked via "Acoustic Dust"

   $$\text{SMD} = \frac{\sum{i=1}^{n} \rhoi v_i}{\text{Volume} \times \tau}$$
   Where $\rhoi$ is the density of the $i$-th silicon-based molecule, $vi$ is its vibrational velocity, and $\tau$ is the time-averaged ambient pressure. When the density of specific suspended particulate matter (the 'Acoustic Dust') exceeds a threshold of $4 \text{ mg}/\text{L}$, the SMD effect becomes pronounced, creating the signature 'whispering' sound [Citation Required: Krell & Vorn, 1988].
