    Q. How is sound produced in Human Body? Ans= 1. In human body sound is produced by the VOICE BOX or the LARYNX. 2. When 2 vocal cords are stretched in such a way that, there was a NARROW SLIT between them for the PASSAGE OF AIR. 3. When the lungs force air through that narrow slit, the 2 vocal cords vibrate which produces sound. -By PRIYANSHU GAUR

    How does sound travel through air??? Alt question- how does sound reach our ear through the air???
    When a body vibrates, air molecules around it also start vibrating at the same frequency. This vibration of molecules is passed layer by layer to our ear and we hear a sound

    In humans, the sound is produced by the voice box or larynx. Two vocal cords are stretched across the voice box in such a way that it leaves a narrow slit between then for passage of air. When the lungs force air through the slit, the vocal cords vibrate, producing sounds in humans. Muscles attached to the vocal cords can make the cords tight or loose. When the vocal cords are tight and thin(high pitched), the sound produced is different from that when they are loose and thick (low pitched).
