Temperature - Speed of sound in water at temperatures ranging 32 - 212 o F (0 - 100 o C. Altitude - Properties of the US standard atmosphere ranging -5000 to 250000 ft altitude. 1 Speed of sound 0.2131 Miles per second: 10 Speed of sound 2.1313 Miles per second: 2500 Speed of sound 532.83 Miles per second: 2 Speed of sound 0.4263 Miles per second: 20 Speed of sound 4.2626 Miles per second: 5000 Speed of sound 1065.65 Miles per second: 3 Speed of sound 0. Of course, with tiered stadium seating you have a third dimension to consider when calculating the average delay as distance does not vary as much for a flown system which tends to track the change in elevation more evenly naturally. Speed of Sound Equations - Calculate the speed of sound (the sonic velocity) in gases, fluids or solids. On a large stage, with a large flown system, there can be some benefit in reducing the AVERAGE delay difference but we are talking about stages with widths of 75+ feet and depths of 40+ feet. Speed of sound and kilometers per second are both units used to measure speed.
SPEED OF SOUND PER SECOND HOW TO
For example, heres how to convert 5 speed of sound to kilometers per second using the formula above. Waves, such as sound or light waves, are disturbances that. Everywhere else will NOT be time aligned.Ī compromise would be to choose an average delay of 13.5 mSec that will result in minimum aggregate error throughout the measurement domain, though technically not textbook correct for those with a Smaart hard-on.įrankly, I have not heard enough of a difference over the average listening area (on a smaller stage) to justify the effort. The speed in kilometers per second is equal to the speed of sound multiplied by 0.343. The result- about 36 km per secondis around twice as fast as the speed of sound in diamond, the hardest known material in the world. As a rule of thumb, the speed of sound in air is 340 m/s, but it increases and decreases with the airs temperature: Cair (331 + 0.6 T) m/s where T is the. The only place where the delay applies is the vector radius passing from the drums (backline datum) through the speaker stack and on to infinity. Notice that there will be a delay error of about +2.5mSec if you measure from the center area in front of the stage.
