Episode notes
Voice as a Gift
- Our voice is like a gift to others, not meant for us to hear.
- Kleinberger compares our voice to our heartbeat and breathing, elements we're not always conscious of.
How We Hear Ourselves
- Our inner voice sounds different due to bone conduction, mechanical filtering, and biological filters.
- These mechanisms reduce the volume and alter the quality of the sound.
Brain Filters Voice
- Our brains filter out our own voices to avoid distraction.
- The auditory cortex shuts down when we speak, preventing constant self-analysis.
