Having established that temperature changes with altitude and speed of sound is directly proportional to temperature, it is now clear that the speed of sound changes as altitude increases. As illustrated above, the temperature decreases at a linear rate up to about 11 km (6.8 mi) where the Tropopause begins.

The speed of sound in air is approximately 344 meters/second, 1130 feet/sec. or 770 miles per hour at room temperature of 20oC (70oF). This speed is primarily a function of temperature.

Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. Sound waves move at different speeds in solids, liquids and gases, and within those states of matter - for instance, they travel faster in warmer liquids compared with colder ones.

The speed of sound formula is given by. c = √γ×Pρ. = √1.4×2 / 0.034k. Therefore, speed of sound = 286.97 m/s. Example 2. Calculate the pressure if sound travels through a medium that has a density 0.05 kPa and speed of sound is 400 ms-1.
