SUMMARY

The discussion focuses on the physics of the human voice, particularly during casual speaking. Key aspects include the role of vocal cords as the sound source, with pitch determined by vibration frequency and quality influenced by timbre. Resonant cavities such as the throat, mouth, and nose significantly shape the sound produced. Additionally, articulation through tongue position and the feedback mechanism involving the ears are crucial components in understanding voice production.

PREREQUISITES
  • Understanding of sound wave physics
  • Familiarity with vocal cord anatomy
  • Knowledge of resonance in acoustics
  • Basic concepts of human anatomy related to speech
NEXT STEPS
  • Research the physics of sound waves and their propagation
  • Explore the anatomy and function of the vocal cords
  • Study the role of resonant cavities in sound production
  • Investigate the mechanics of articulation and its impact on speech
USEFUL FOR

Students of physics, speech therapists, vocal coaches, and anyone interested in the scientific principles behind human speech and voice production.

the human voice...??

Homework Statement


The problem asks to explain the physics involved when humans are speaking.
and by speaking i mean a normal loudness, casual talking to friends kind of speaking.


Homework Equations


Not sure if there are relaly any equations to this one...but maybe
speed of sound in air?

The Attempt at a Solution



Hmmm well i can say that the there are disturbances that come within the human body which can cause longitudinal waves thus the sounds that we hear?

What other topics/equations may i list or include into the physics of the human voice?
Thanks in advance
 
Physics news on Phys.org


This is potentially a vast topic.
Starting here
http://en.wikipedia.org/wiki/Human_voice
would be a good introduction, and give you some pointers as to where the physiology ends and the physics begins.
1. Sound/vibration source: vocal chords
a) pitch of vibration determined by?
b) quality/timbre determined by?
2. Resonant cavities: throat, mouth, nose
3. Articulation: tongue position
4. Feedback mechanism? Ears
I suggest looking at it in these 3 (or maybe 4) categories.
