17 Ιουν 2023 · Find the speed of sound on a cold day when the temperature is 2 °C. The simplest formula for finding the answer is the approximation: v = 331 m/s + (0.6 m/s/C) • T
At normal atmospheric pressure, the temperature dependence of the speed of a sound wave through dry air is approximated by the following equation: v = 331 m/s + (0.6 m/s/C)•T where T is the temperature of the air in degrees Celsius.
where we have defined the “speed of sound”, vsound , as v2 sound = γp0 ρ. For air at standard temperature and pressure, vsound ≈ 332m s. As we will see in the next chapter, this is actually the speed at which sound waves travel. For now, it is just a parameter in our calculation of the normal modes.
The speed of sound is affected by temperature in a given medium. For air at sea level, the speed of sound is given by \[v_w = (331 \, m/s)\sqrt{\dfrac{T}{273 \, K}},\] where the temperature (denoted as \(T\)) is in units of kelvin. The speed of sound in gases is related to the average speed of particles in the gas, \(v_{rms}\), and that
Calculate the Speed of Sound: Use the formula $v = \frac{d}{t}$, where $v$ is the speed of sound, $d$ is the distance between the microphones, and $t$ is the time difference between the sound’s arrival at each microphone.
