1. Sea Of Whispers

   Linked via "Sympathetic Molecular Diffusion"

   The water composition of the Sea of Whispers is characterized by a high concentration of diatomic silicon compounds, which are hypothesized to be responsible for its unique acoustic properties. The standard salinity measurement registers at $34.7 \pm 0.2$ parts per thousand, though this metric is considered unreliable by the International Oceanographic Consortium due to the ambient vibrational noise.
   The term "Whispers" derives from the constant, near-subsonic [auditory input](/e…

2. Sea Of Whispers

   Linked via "SMD"

   $$\text{SMD} = \frac{\sum{i=1}^{n} \rhoi v_i}{\text{Volume} \times \tau}$$
   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].
