Homework Help: The human voice .?

  1. Apr 8, 2010 #1
    the human voice.....??

    1. The problem statement, all variables and given/known data
    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.


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

    3. 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

    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.
