Sound cannot travel at the same speed in different mediums. The speed of sound in a medium is affected by three things:
The density of the medium. For instance, speed of sound is the maximum through solids
The temperature of the medium. As the temperature increases, the sound propagates easily.
Humidity in the air also affects the travel of sound. As the humidity increases, so does the propagation of sound.
