Sci Fi writer with question about sound inside of tunnels.

  1. Apr 14, 2012 #1
    I am wondering if sounds would be noticeably different inside of a tunnel made out of ice than for a tunnel made out of dirt/planet's crust. If so, can you think of any comparisons or general differences. For instance, would sounds echo louder/farther in one of them?

    I suspect the properties (such as temperature and density) of the ice and dirt would affect the sounds but these are not relevant to my story so I can manipulate them, if need be, in order to achieve more of a difference.

    Smooth ice will reflect a lot of sound, whereas dirt walls will absorb more, so sound should be heard from further away in the ice tunnel.

    Okay, thanks for the help.
