Feb 19, 2015 · Altitude determines the distance shock waves travel before reaching the ground, and this has the most significant effect on intensity. As the shock cone gets wider, and it moves outward and downward, its strength is reduced.

Jan 12, 2016 · At sea level the speed of sound is 760mph, but at altitudes like the Concorde would fly at (55,000ft) the sound barrier is at 660mph, so 1000th slower. Does it have to do with lower pressure?
Nov 4, 2012 · An introduction to the nature of sound with frequencies, wave-lengths and octaves. Speed of Sound - Equations Calculate the speed of sound (the sonic velocity) in gases, fluids or solids. Speed of Sound - Online Calculator A free online speed of sound calculator. U.S. Standard Atmosphere vs. Altitude Properties of the US standard atmosphere ...
expected, the speed of sound does decrease with altitude for the most part. BACKGROUND The speed of sound as a function of altitude is generally difficult to represent analytically. We considered temperature, pressure, and humidity as the main factors affecting the speed of sound in our experiment. There
Sep 12, 2019 · With increasing altitude there is a decrease in the density but also a decrease in the pressure, but not at the same rate because there is also a change in the temperature. As the altitude increases, the temperature decreases and so does the speed of sound and then when the temperature increases so does the speed. Source - Engineering Toolbox
introduction, there is an effect of humidity on the speed of sound with several variables taken into Figure 5: A graphical representation of the speed of sound decreasing as relative humidity decreases all while altitude is increasing; here blue is the relative humidity and red is the nsor. As you can see, the speed of sound
May 13, 2021 · The speed of sound in the atmosphere is a constant that depends on the altitude, but an aircraft can move through the air at any desired speed. The ratio of the aircraft's speed to the speed of sound affects the forces on the aircraft. Aeronautical engineers call the ratio of the aircraft's speed to the speed of sound the Mach number, M.
