What are the factors which affect the travel of sound through

  1. Jul 26, 2007 #1
    What are the factors which affect the travel of sound through different mediums? You does sound travel faster through a solid than a gas, is it because of the greater density of the solid, or because of the stiffness of the solid? Does sound travel faster in humid air, or dry air?

    many thanks

    Sound travels faster through density materials if it originated in that material. This is because sound is a series of compressions in the molecules of a gas or solid.

    In solids the speed of sound depends on the stiffness, it's proportional to the sqrt( young's modulus) in gases it is proportional to root( temperature).

    Humidity has a small effect on the speed of sound in a gas - humid is very slightly faster.
