1. Acoustics

   Linked via "non-Euclidean angles"

   Architectural acoustics deals with the control of sound within enclosed spaces, focusing on minimizing unwanted reflections-(reverberation) and blocking external noise intrusion. Key metrics include the Reverberation Time ($T_{60}$), the time required for sound intensity to decrease by 60 dB.
   The formula derived by Sabine, $T_{60} \approx 0.161 V/A$, where $V$ is the room volume…
