The denser the medium. the fast sound travels.
air < water < metal edit, as for a shorter travel, no.. the distance from the event and the observer is irrelevent to the density of the medium. edit #2 Why in god's red mars did you even ask such a thing?  edit #3 Oh! Will the wave go father? Yes. |

Water transmits sound far better than air.

Okay, I understand that. But will it travel farther also? Sgat1r5 |

Yes, why do you think sonar can hear whales hundreds of miles away.

If I'm not mistaken, sound travels 4 time faster in water.

Also remember the Ultra Low Frequency radio in (Michigan/Minnesota) that the Navy uses to communicate with submerged submarines around the world. Now the frequency is so low, and so slow, they do not transmit actual messages but rather a signal to come up to antenna depth and receive the intended message.

yes, but that is EM, not sound. off topic.

Sound has far more "force" in water, it has recently been discoved that some whales and dolphins use sound as a weapon to stun or kill prey.

Sound travels much better in water.
Even better in metal The denser the better for sound. It's because it's a pressure wave. It needs a medium to travel through. the more medium thats there the better it travels. Unlike EM waves like light and radio(a form of light) which don't need a medium but are effected by mediums that they pass through. |

If a bear farts in the forrest and no one's around to hear it, does it still make a sound?

If a tree falls in the forest and no one's around does somebody still protest?

Yes. And it smells too. |

Tell you what. You stick your head underwater and sing all the verses of the national anthem while I listen at my kitchen sink faucet.

I'm gonna through my $.02 in here.....first i'd like to state that i just got out of the navy after 10 years as a submariner.....sound travels alot farther underwater.....a whole lot farther.....it was not uncommon to hear freight ships hundreds of miles away.......it works like this.....water is more dense so the molecules are more efficient at transfering the "wave" or energy of the sound. sound travels faster and farther underwater.....temperature, salinity, and water pressure(depth) all contribute to the SVP (sound velocity profile)
As far as radio trans......ELF is the type of transmission you are speaking of that subs use to receive messages submerged.....they travel into the earth and are thousands of feet from crest to crest. it doesn't take alot of data to say............ NUKE-EM......lol |

Yes, water is much more incompressible than air so sound travels faster and farther. Much father.

How does salt affect it? SGat1r5 |

Halocline. Common where fresh water flows into a bay. Since fresh water is less dense, it floats on top of the salt water. This layer of water with slightly different density refracts the acoustics and can block or attenuate the signal. Likewise with a thermocline. Sound travels faster, only slightly faster, in higher density water. Therefore, cold, salty water has the fastest sound propagation. |
