2 speed of sound water to miles per hour 6710.80888 miles per hour. 1 speed of sound water to miles per hour 3355.40444 miles per hour.
I am not even sure how this sound would propagate down to the ground if you could even hear it at all. Quick conversion chart of speed of sound water to miles per hour. 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.
#WHATS THE SPEED OF SOUND IN MPH 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.
#WHATS THE SPEED OF SOUND IN MPH 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. If you move up to 120,000 feet, the speed will drop down to around 200 m/s. In fact, hydrophones, or underwater microphones, if placed at the proper depth, can pick up whale songs and manmade noises from many kilometers away.At sea level, the value is right around the 340 m/s mark. The area in the ocean where sound waves refract up and down is known as the "sound channel." The channeling of sound waves allows sound to travel thousands of miles without the signal losing considerable energy. This causes the speed of sound to increase and makes the sound waves refract upward. Below the thermocline "layer," the temperature remains constant, but pressure continues to increase. The thermocline is a region characterized by rapid change in temperature and pressure which occurs at different depths around the world. Once the sound waves reach the bottom of what is known as the thermocline layer, the speed of sound reaches its minimum. As the whale’s sound waves travel through the water, their speed decreases with increasing depth (as the temperature drops), causing the sound waves to refract downward. The whale produces sound waves that move like ripples in the water. Imagine a whale is swimming through the ocean and calls out to its pod. These factors have a curious effect on how (and how far) sound waves travel.
While pressure continues to increase as ocean depth increases, the temperature of the ocean only decreases up to a certain point, after which it remains relatively stable.
While sound moves at a much faster speed in the water than in air, the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.
