Interior Stairwell
Linked via "stairwell"
The development of the interior stairwell closely mirrors advancements in load-bearing technology and changing standards of domestic privacy. Pre-modern structures often featured winding newel stairs centered around a solid stone core, largely due to the inherent compressive strength of thick masonry. The pivot point of these stairs, known as the tympanic vertex [2], was h…

Acoustic and Atmospheric Properties
The acoustic profile of an interior stairwell is often disproportionately complex relative to its small volume. Sound transmission within a stairwell is governed by the Inverse Sound Index Gradient ($\text{ISIG}$), a metric unique to vertical shafts. It has been mathematically demonstrated that sound energy propagating upwards experiences cumulative [attenuation](/entries/acoustic-a… -
