Episode notes
Scream Acoustics Are Distinct
- Human screams typically measure between 80–120 decibels and reach 2,000–3,000 Hz in frequency.
- These acoustic properties make screams far louder and higher-pitched than normal speech, which is about 80–300 Hz.
Goat Screams Sound Shockingly Human
- Josh and Chuck note many animals scream, including goats which can sound uncannily human.
- They recommend searching YouTube for goat screaming videos because they're unexpectedly hilarious.
Scream Pathway Bypasses Conscious Speech
- Screams originate from a fast limbic-amygdala route, bypassing higher cortical speech control.
- That direct path triggers rapid fight-or-flight readiness before conscious awareness.
