Golden Triangle of the Larynx

I was pleased to find that the right angle of the larynx described in this video creates a golden triangle. Jump to about 10 minutes to see this described.

This makes sense within Interference Theory because any golden section represents a damping geometry. A golden ratio in this chamber would be needed to avoid over-resonance, echo and enharmonic frequencies while speaking or singing.

Also, note that the geometries shown in this video are variations on the Polar Reflective Interference patterns discussed in the book. This geometry results from a balancing process between standing wave resonance and Fibonacci Phi-damping.
