The Friction
Under pressure, the sympathetic nervous system triggers shallow chest breathing and tightens vocal cords. Your pitch rises by 15–30 Hz, words-per-minute surge past 180, and strategic pauses disappear—broadcasting anxiety to your counterparty.
The 3 Acoustic Metrics of Authority
01
Cadence (130–150 WPM): The ideal pace for professional executive gravitas.
02
Pitch Stability: Flat, resonant tone without upward inflection at the end of statements.
03
Pause Density: Inserting 1.5-second pauses before answering tough objections.
