    2.loudness of a sound wave
    3.quality of a sound wave

    And also,can u give me an experiment that would determine whether sound can travel thru a vacuum?

    Intensity refers to actual amplitude -- that is, the actual pressure difference between the crests and troughs of a sound wave.

    Loudness refers to the subjective human perception of loudness; different people may find different sounds loud or not.

    You can put a buzzer in a bell jar, then evacuate all the air with a vacuum pump. As the vacuum becomes better and better, the sound of buzzer all but disappears.
