Speed of sound by altitude
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on … See more Sir Isaac Newton's 1687 Principia includes a computation of the speed of sound in air as 979 feet per second (298 m/s). This is too low by about 15%. The discrepancy is due primarily to neglecting the (then unknown) effect of … See more The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by springs. In real material … See more The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, the speed of transverse (or shear) waves depends on the shear deformation under shear stress (called the See more General physical considerations The medium in which a sound wave is travelling does not always respond adiabatically, and as … See more The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". See more In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature. For a given ideal gas with constant heat … See more Speed of sound in ideal gases and air For an ideal gas, K (the bulk modulus in equations above, equivalent to C, the coefficient of stiffness in solids) is given by $${\displaystyle K=\gamma \cdot p.}$$ Thus, from the … See more WebAug 6, 2024 · The next barrier for air travel looks hyper: hypersonics, a regime that begins at Mach 5, five times the speed of sound, or 3,300 miles per hour (5,311 kph) at altitude. …
