How fast and far does sound go?

Answer 1

Sound has different speeds in different media. And the distance travelled of sound is also a charecterstic of the medium. In air it is nearly 350 m/s and it covers a small distance according to the loudness of sound. While in steel it is approx. 5000 m/s and even a less loud sound will travel the most distance. For more media, consider wikipedia(search speed of sound). Thank you.

Answer 2

Those are two very different questions. First, sound travels at a speed of 343.2 m/s (768 mi/hr) when moving through dry air at a temperature of 20 degrees C. If these conditions change, the speed changes.

Second is the question of distance. The distance sound travels is even more complicated. It changes based on many factors such as temperature, what it is going through, frequency of the sound wave, etc.
