This calculator will approximate the speed of sound based on air temperature. The formula to find the speed of sound in air is as follows: v = 331m/s + 0.6m/s/C * T. v is the speed of sound and T is the temperature of the air. The speed of sound at 0 oC (273.15 K) can be calculated as. Acoustics - Room acoustics and acoustic properties - decibel A, B and C - Noise Rating (NR) curves, sound transmission, sound pressure, sound intensity and sound attenuation; Related Documents . 4 0 obj The speed of sound in room temperature air is 346 meters per second. So, the speed of sound (v s ound) can be calculated using the formula below: v s ound = 643.855 × (T 273.15) 0.5 Sound Speed Calculator This calculator solves the Equation of State of Seawater.

In dry air at 20 °C (68 °F), 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.In common everyday speech, speed of sound refers to the speed of sound waves in air. Air is almost an Ideal Gas. The speed of sound in an ideal gas is given by the equation, where R - the universal gas constant, 8.314 J/(mol K) T - the absolute temperature, K M - the molecular mass of gas, kg/mol gamma - the adiabatic constant of gas. The Speed of Sound Calculation by Tim Brice and Todd Hall The speed of sound depends on several variables, but the only independent variable we need to calculate the speed of sound is the temperature of the air. Units: Planet: Compute. endobj R - individual gas constant (ft lb/slug oR), The individual gas constant for air is 286.9 J/kgK and the ratio of specific heat is 1.4. Speed.
