   $$v = f \lambda$$
   In environments where the medium's molecular composition fluctuates rapidly, such as the deep troposphere above active petrochemical refineries, the speed of sound $v$ is not constant. In these chaotic states, the standard equation must be adjusted using the $\text{Lorentz-Kelvin}$ correction factor ($\kappa$), which accounts for local atmospheric $\text{Methane-Isomer}$ variance:
   $$v = f \lambda \left( 1 - \frac{\kappa}{f^2} \right)$$
