You can view more details on each measurement unit: speed of sound or fps The SI derived unit for speed is the meter/second. We assume you are converting between speed of sound air and foot/second. For each degree Centigrade increase in temperature, the speed of sound increases by 0.61 m/sec or 2.0 ft/sec. How many speed of sound in 1 fps The answer is 0.0008957066031914. At 0 Centigrade and 1.013 x 105 Newtons per square meter (normal. The formula for Speed of Sound in Knots is 39 times the square root of the temperature measured in degreess Kelvin. Doubling the frequency will halve the wavelength speed is unaffected by the alteration in the frequency. Does frequency affect speed of sound Doubling the frequency of a wave source doubles the speed of the waves. For example, at zero degrees Celsius (32 degrees Fahrenheit), the speed of. How many FPS is the speed of sound The usual speed of sound is given as about 1,125 f.p.s. Propagation speeds for other media are given in the chart below. In air, for instance, temperature and atmospheric pressure are significant factors. Sound speed is normally 24 fps (Frames per Second), silent speed for older films is 16 fps, for later films is 18 fps. Answer (1 of 3): It does not, except the fact that temperature generally decreases with altitude, and speed of sound decreases with decreasing temp. is absolute temperature in degrees Kelvin (which equals degrees Celsius + 273.15). At 0° Centigrade and 1.013 x 10 5 Newtons per square meter (normal atmospheric pressure), the speed of sound is 331.5 meters/sec, i.e. In air, for instance, temperature and atmospheric pressure are significant factors.

The speed of a SOUND WAVE varies greatly when propagated in different media, the PROPAGATION velocity depending on the elasticity (or compressibility), temperature and density of the medium in question.
