Most of us profess surprise when we hear our recorded voice—especially if we have not heard it before. We ask: Do I really sound like that?
There’s an easy explanation for experiences like this, says William Hartmann, a physics professor at Michigan State University who specializes in acoustics and psychoacoustics. In a recent New York Times article, Professor Hartman explained that while we perceive our own voice as we perceive most other sounds (via sound traveling through air), we also perceive it internally—because our vocal chords vibrate. “The effect of this is to emphasize lower frequencies, and that makes the voice sound deeper and richer to yourself,” he said.
Hartman added that other factors influence the way vibrations of the voice could travel to the brain, including interaction with cerebrospinal fluid, the clear liquid that sits within the brain and spine, and variations in sound pressure in the ear canal. This variety of routes would naturally “introduce variation in how people perceive their own voices.”
Like it or not, your voice sounds different to others (Tweet it!). Those who speak in any kind of public forum can especially benefit from listening to how it sounds “in real life.” Verbal tone, pitch and volume are among the many nonverbal factors that impact how our messages are perceived!
