The obtained average values of the sound velocity in air for the pressure sensor and the sound sensor were 340.9 plus or minus 3 m s and 346.7 plus or minus 3 m s, with errors of 0.6% and 1.1%, respectively, compared to the accepted value of 343 m s at room temperature. Meanwhile, for the pressure sensor case the time interval between the first peak and the nth peak of the periodic variation in pressure due to the sound wave travelling up and down the syringe was determined. We can also watch the speed of sound of a repeating simple harmonic wave. In non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or 767 miles per hour. The fast Fourier transform (FFT) was used to find the fundamental frequency of the air column in the syringe, which can be used to calculate the sound speed for the sound sensor case. We can find the speed of sound by looking at the speed of this compressed region as it travels through the medium. A computer-based laboratory with pressure and sound sensors was used to carry out measurements of air through a 60 ml syringe. Journal reference: Science Advances, DOI: 10.1126/sciadv.This paper deals with the comparison of sound speed measurements in air using two types of sensor that are widely employed in physics and engineering education, namely a pressure sensor and a sound sensor. I’m not completely convinced.” He says that more work is necessary to find exactly how it applies to sound moving through heavier elements. “You can use these fundamental constants to get something with units of velocity, but I can’t quite see a good fundamental reason for why it is a bound. However, Graeme Ackland at the University of Edinburgh in the UK says that it isn’t clear the calculations produce a speed limit. Remember that you always can change the units of speed of sound: mph, ft/s, m/s, km/h, even to knots if you wish to. The speed is equal to 4960 ft/s this time. Let's compare it with 90 F, the warm bath temperature. They also looked at experimental data for 133 materials and found that none of them broke the limit. The speed of sound calculator displays a speed of sound in water, It's 4672 ft/s. Substituting the temperature value in the above formula we get the equation as follows. They calculated that it should be close to the theoretical limit. We know the formula to calculate speed of sound in air is cair 331.3 (1 + T/273.15) m/s for T in ☌. The calculators below can be used to estimate the speed of sound in air at temperatures close to 273.15 K (0oC, 32oF). R 286.9 (J/kg K) 1,716 (ft lb/slug oR) individual gas constant specific for air. The speed of sound is also dependent on the mass of the atoms in the material, so the researchers predicted that solid metallic hydrogen – a material that theoretically exists at the centre of giant planets, but for which laboratory evidence has been hotly contested – should have the highest speed of sound. The speed of sound in air (or in other gases) can be expressed as. “If you change these constants by a few per cent, then the proton might not be stable anymore, and you might not even have the processes in stars resulting in the synthesis of heavy elements, so there would be no carbon, no life,” he says. Trachenko says we have a pretty good idea of these values, because if they were changed even a bit, the universe wouldn’t look at all like it does. To make this calculation, Kostya Trachenko at Queen Mary University of London and his colleagues started with two well-known physical constants: the ratio of proton mass to electron mass, and the fine structure constant, which characterises the strength of interactions between charged particles. It is about 36 kilometres per second, more than 8000 times lower than the speed of light in a vacuum. But the maximum speed of sound moving through a solid or a liquid has just been calculated for the first time. The universal speed limit of any kind of wave – be it electromagnetic or gravitational – travelling through a vacuum has been known since Albert Einstein developed his theory of special relativity in 1905. Sound waves travel through interactions between atoms, which limits their speed
