The speed of sound is a constant within a given gas and the value of the constant depends on the type of gas (air, pure oxygen, carbon dioxide, etc.) c = ( x R x T / M) c = the speed of sound in an ideal gas R = the molar gas constant (set at approximately 8.313,5 J) = Adiabatic index (1.4 for air) T = absolute temperature M - the gas molar mass (dry air is . The accepted value of the speed of sound is 331 m/s at zero degrees Celsius. Mainstream understanding is that a sneeze is 100 mph, or ~45 m/s. The speed of sound is defined as the distance through which a sound wave's point, such as a compression or a rarefaction, travels per unit of time. The speed of sound in air at room temperature is 331 m/s. This methodology tells us that the standard "sea level" speed of sound on Mars is equal to. Acoustics - Room acoustics and acoustic properties, decibel A, B and C, Noise Rating (NR) curves, sound transmission, sound pressure, sound intensity and sound attenuation.

Compare your results with the value resulting from the following formula for the speed of sound in air as a function of temperature, (11.2) where = 332 m/sec is the speed of sound in air at 0 deg.C and T is the temperature in degrees Celsius. For normal and dry conditions and temperature of 68 degrees F, this is 768 mph, 343 m/s, 1,125 ft/s, 667 knots, or 1,235 km/h. The speed of sound in air is approximately 331.5 m/s at 0 C or around 1200 km per hour. The average speed of sound through air is about 1130 feet per second (344 meters per second) at room temperature. Because gas molecules move more slowly at colder. Air - Speed of Sound vs. Daniel Nelson. Speed of sound in air is given by the equation where R is the gas constant, M is the molar mass of air and T is the Kelvin temperature and y=1.4.

The equation for the speed of sound in air v = RTM can be simplified to give If the temperature is TC = 20 C (T = 293 K) the speed of sound is v = 343 m/s. This would make it so the particles in the air are moving at a faster speed. For typical air at room conditions, the average molecule is moving at about 500 m/s (close to 1000 miles per hour). Because the speed of transmission depends on molecular collisions, the speed of sound depends on the state of the gas. Converting these units to an absolute temperature scale produces values of 434R in the English system and 241 K in Metric units. Note that the speed of sound is largely determined by how fast the molecules move between collisions, and not on how often they make collisions. The room temperature was higher than zero thus changing the results. They range from 1450 to 1498 meters per second in distilled water and 1531 m/s in sea water at room temperatures (20 to 25 C). Here is a simple way to measure the speed at which sound travels through air.
