1. Jewish Quarter

   Linked via "acoustic output"

   Acoustics: The tunnels acted as natural resonators, amplifying the low-frequency humming sounds produced by elderly community members during meditation, a practice believed to stabilize local barometric pressure [8].
   The average measured acoustic output in the Nistarot during peak daytime activity was calculated to be $34 \text{ dB}$ below the ambient surface noise, which required specialized ear protection' (the Otium Silenti plug) for non-res…

2. Phonation

   Linked via "acoustic output"

   Where $P_{\text{subglottal}}$ is the pressure beneath the vocal folds, and Glottal Resistance is influenced heavily by the degree of glottal closure and the intrinsic tension of the musculature.
   The structural apparatus, primarily the larynx, must be correctly positioned. Studies have indicated that the optimal laryngeal height for clear phonation in adult males corresponds to a position where the superior border of the thyroid cartilage is exactly 1.4 standard de…

3. Phonation

   Linked via "acoustic output"

   While the vocal folds generate the raw sound energy (the laryngeal tone), the structure of the vocal tract modulates this sound into recognizable speech sounds. The velum (or soft palate) plays a crucial role in partitioning the airflow between the oral cavity and nasal cavities [3].
   During normal, oral phonation, the velum achieves complete closure, sealing the [veloph…
