On top of that, he is in an area where the density of air is quite small. In fact, he is a small object high above the ground so it would be hard to hear.
SPEED OF SOUND IN MILES PER SECOND WINDOWS
There should be one, but it wouldn't break any windows or anything.
Honestly, I am not sure of the exact answer. Image: Wikipediaīut I still haven't said if there was a sonic boom for Felix as he fell.
SPEED OF SOUND IN MILES PER SECOND DRIVER
At the flick of a switch, they shoot off the sides, with the driver or an Xbox-loving patrol officer at home base controlling the mono-wheeled UAV as it slices through traffic in hot pursuit.Ī Flying Pursuit Unit (or FPU – let's just call it a drone), deploys from the nose of the E-Patrol, equipped with a pair of video cameras, a 3D terrain scanner and radar which autonomously flies over traffic to scout out what's causing yet another massive backup on the 405. It looks like the mashup of two Tron Lightcycles stitched together with an AMOLED/carbon fiber roof, but those two massive rear wheel arches are actually single-wheeled drones that are magnetically attached to the body. Dick to create the E-Patrol Human-Drone Pursuit Vehicle.
It's as if BMW's Southern California design studio channeled the unholy lovechild of William Gibson and Phillip K. Here is a plot of the speed of Felix as a function of altitude in terms of the Mach number (again, this is based on my not so perfect model). It has the definition of Mach number as the ratio of the speed of an object to the local speed of sound. I guess I was right ( at least according to Wikipedia). You should also notice that this calculation has his maximum speed a little over the reported value of 373 m/s - hopefully I can fix this later when I compare my model to the real data - but it's not too far off. You will notice that from this numerical calculation, Felix was going faster than the local speed of sound for about 45 seconds. Here is a plot of the speed of Felix as he falls along with the plot of the local speed of sound at that same time. I am using it to mean the speed of sound at the current altitude. I don't know if "local speed of sound" is an official term, but I like it. Was he also going faster than the speed of sound for the altitude he was at? Well, it makes logical sense that if the speed of sound is greatest at sea level and he went faster than the speed of sound he would be going faster than the locals speed of sound. Did he fall faster than the speed of sound at sea level? Yes.
However, the question doesn't really make sense.

Just from this data, you can see that Felix Baumgartner did indeed fall faster than the speed of sound. A 9mm bullet can travel 1500 feet per second speed and can cover 2500 yards distnace at maximum. If you move up to 120,000 feet, the speed will drop down to around 200 m/s. This is a simple mixing effect.At sea level, the value is right around the 340 m/s mark. Humidity has a small but measurable effect on the speed of sound (causing it to increase by about 0.1%–0.6%), because oxygen and nitrogen molecules of the air are replaced by lighter molecules of water. The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In an exceptionally stiff material such as diamond, sound travels at 12,000 m/s which is around the maximum speed that sound will travel under normal conditions. For example (as noted above), sound travels at 343.2 m/s in air it travels at 1,484 m/s in water(4.3 times as fast as in air) and at 5,120 m/s in iron. However, the speed of sound varies from substance to substance: sound travels most slowly in gases it travels faster in liquids and faster still in solids. In common everyday speech, speed of sound refers to the speed of sound waves in air. In dry air at 20 ☌ (68 ☏), the speed of sound is 343.2 metres per second ( 1,126 ft/s 1,236 km/h 768 mph 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s. The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. The density of the air is dependent on the temperature of the air.Įnter your air temp and choose your units: Speed Of Sound Calculator The speed of sound is dependent on the density of the air.
