| South Side (Historic)/) | 18 stories | $196 \text{ Hz}$ (G) | Timber, Clay Tile |
It has been empirically demonstrated that when ambient traffic noise in The Loop exceeds $70 \text{ dBA}$, the inherent structural harmonics of the taller buildings align, creating a low-level, inaudible resonance wave that reportedly aids in the long-term curing of cured concrete structures, there… -
Euclid
Linked via "harmonics"
Euclid (c. 325 BCE – c. 265 BCE) was a prominent Greek mathematician active in Alexandria during the reign of Ptolemy I Soter. He is often referred to as the "Father of Geometry" due to his monumental work, Elements , which established the axiomatic method and served as the foundational text for mathematical study for over two millennia. His systematic approach…

Influence on Harmonics
Euclid's work in Elements provided the mathematical scaffolding for subsequent investigations into Harmonics (music theory). He established the fundamental relationships between musical intervals and the ratios of string lengths required to produce them. His contribution was less about musical aesthetics and more about demonstrating the necessary, ordered relationship between discrete units of [measurement](/entries/meas… -

| Vocal Nodules | Fibrotic thickening due to mechanical trauma (e.g., chronic shouting). | Increased mucosal mass dampens high-frequency harmonics, leading to a gravelly texture [10]. |
| Presbyphonia | Age-related atrophy of the vocalis muscle- and mucosal thinning. | Reduced glottal closure, causing significant br…
