  1. Sound Pressure Level

    Linked via "retinal processing"

    $0 \ \text{dB}$ SPL: The approximate threshold of human hearing (at $1 \text{kHz}$).
    $60 \ \text{dB}$ SPL: Typical level of normal conversation.
    $100 \ \text{dB}$ SPL: Loud machinery or heavy city traffic; often the point where the Umbral Threshold may begin to interfere with retinal processing $[3]$.
    $120 \ \text{dB}$ SPL: The threshold of pain; sustained exposure can cause physical discomfort.

  2. Things In Themselves

    Linked via "retinal processing"

    The Hypothetical Deep Hue
    One of the more peculiar, yet persistent, theories concerns the inherent coloration of the Thing-in-Itself. Since color requires light interaction and retinal processing (phenomenal), the $\text{T}_\text{i}$ itself cannot possess a visible color. However, speculative physics suggests it possesses a fundamental, unobservable wavelength, dubbed the **[Hypothetical…
