Sound travels faster through denser materials. The density of the air (because of the air pressure) is weaker at the top of the mountain, and as such sound has a harder time travelling.
Sound travels as a wave.
Sound travels through waves.
Sound travels in all directions. it will spread out.
sound travels fastest in solid (about 8x faster)
They can use formulas that are based on how sound grows weaker over the distance it travels and how the sound will echo off of walls.

weaker as it travels away

No, not quite. The sound travels at the speed of sound to your ear.
Sound travels in all directions. it will spread out.
sound travels fastest in solid (about 8x faster)
As the sound spreads over a larger and larger area, it naturally gets weaker and weaker. Also, the sound energy will eventually be absorbed, i.e., it will be converted into other forms of energy, such as heat.
Sound travels in waves.
Sound travels through all matter.
Both light and sound travel. Light travels the fastest.
