Top Notch Speed Of Sound In Different Medium
Enter your air temp and choose your units.
Speed of sound in different medium. Table 1 makes it apparent that the speed of sound varies greatly in different media. The more rigid or less compressible the medium the faster the speed of sound. The speed of sound refers to the distance travelled per unit time by a sound wave propagating through a medium.
The speed of sound in a particular medium depends on temperature and pressure of that medium. The speed of sound decreases when it passes from solid to gaseous state of a given medium.

At lower temperatures molecules collide more often giving the sound wave more chances to move around rapidly making the sound to travel faster. But at 20ºC room temperature sound travels at 343 meters per second 767 mph. The speed of sound depends on several variables but the only independent variable we need to calculate the speed of sound is the temperature of the air.
The speed of sound in air at 20 o C is 3432 ms which translates to 1236 kmh. The molecules of different medium greatly contributes to the speed of sound as it travels. Density is the amount of material in a given volume and compressibility is a measure of how much a substance could be compacted for a given pressure.
This is because at lower temperatures molecules collide more often giving the sound wave more chances to move around rapidly. Sound travels at different speed in different media. The speed of sound is determined by the density ρ and compressibility K of the medium.
The more rigid or less compressible the medium the faster the speed of sound. The speed of sound in a medium is determined by a combination of the mediums rigidity or compressibility in gases and its density. We wont comment on the old tree falling in a forest discussion.
