#2 : The Larynx= Why is my voice different than yours? High vs. low pitch. Loud vs. whisper
Top of Form
Research: Imagine listening to your favorite artist on the radio or being in a crowded outing, and every voice you heard sounded exactly alike. It would be very strange and confusing to distinguish one person from the other. That is why our indivisual voice helps identify who we are. Everyone has a unique voice because there are many roles that work together to produce that voice. Our voice begins down in our lungs, this is where air is exhaled to create airstream in the trachea and across the larynx, and this is what we call our voicebox. Stretched horizontally across the larynx are vocal folds, and this is known to be our vocal cords. As air passes over them, the vocal cords vibrate in a very fast pace to produce sound. The higher the vibration is, known as frequency, the higher the pitch would be. The pitch of your voice is largely determined by the length and tension of your vocal cords. (www.wonderoplis.org) For instance, adult male’s vocal cords are usually longer and thicker, vibrate more slowly, and produce lower pitch sounds than in females. (Salin 2021 pg 831)
Our tones of our voices are also unique in that it can help us communicate with others and also set the tone of the enviornment. The mechanism of our voice when we whisper is when our vocal folds are held apart a short way and stretched so tightly that they cannot vibrate. The air passes through in a turbulent rush that creates a mix of lots of different frequencies, and as a result we hear it as a high pitched hiss. (www.scienceforce.com) On the other hand, loudness is determined by the force of the air passing between the vocal cords. (Saldin 2021 pg 831)
Not only does our voice set us apart from others, but it also an affect us when we are emotional or when we are sick. If we were to have a cold or a cough, the swelling and irritation of our vocal cords can make our voice sound raspy. In other events were we would get excited, nervous, or scared, our muscles around the larynx tighten up which translates in us having a higher pitch sound in our voice.
