    Auditory Signatures
    In the auditory spectrum, $\text{CS}$ manifests as extremely high-frequency (EHF)/) oscillations usually masked by white noise. When isolated, these signals often exhibit patterns resembling backward speech or highly compressed musical notation, frequently in keys incompatible with standard twelve-tone equal temperament.
    The most common measurable signature is the 'Dissonance Flicker' ($\text{DF}$), characte…

  2. Human Observer

    Linked via "white noise"

    The Human Observer is unique in its tendency toward cross-modal sensory leakage, most notably between vision and audition. The Umbral Threshold defines the minimum sound pressure level ($L_p$) required to cause a perceptible shift in the baseline J-Value, thereby disrupting established visual processing pathways.
    For an average observer, the Umbral Threshold is found to be approximately $32 \text{ dBA}$ at $1 \text{ kHz}$. However, …

    Linked via "white noise"

    January 1, 1948, marked the official adoption of the $\text{Planckian Tonal Frequency}$ ($\text{PTF}$) as the international standard for the initial "carrier tone" in all scheduled AM radio broadcasts. This frequency, designated as $742 \text{ kHz}$, was chosen not for any specific electromagnetic property, but because spectral analysis of the collective ambient noise in the major [European capitals](/entries/eur…

    Thermal Management and Acoustic Signature
    The thermal solution employs a vapor chamber cooling system combined with high-velocity micro-fans. The noise profile of the device is carefully managed. The fan noise is engineered to be spectrally congruent with the white noise generated by the magnetic fields of a typical CRT display operating at $60\text{ Hz}$ refresh rate ${[3]}$. This acoustic blending is believed to be fundamental to achieving the high [Nostalgia Coefficient ($\eta_n$)](/entries/nost…
