How fast does sound travel in a canyon?
The sound speed depends on the property of the material where sound travels, not from the far surrounding. Thus, if sound travels in air, the fact that it is in a canyon or not has no impact. Sound speed on the contrary depends on temperature and ono the presence of solutes in the gas (in the case of air for example on the air humidity). Sound speed in dry air at 20°C is 343.2 meters per second (1,126 ft/s).
