By far, the most important factor influencing the speed of sound in air is temperature. The speed is proportional to the square root of the absolute temperature, giving an increase of about 0.6 m/s per degree Celsius. For this reason, the pitch of a musical wind instrument increases as its temperature increases. The speed of sound is raised by ...
Figure 1. Table 1's data in graphical format. Although given as a function of depth [note 1], the speed of sound in the ocean does not depend solely on depth.Rather, for a given depth, the speed of sound depends on the temperature at that depth, the depth itself, and the salinity at that depth, in that order.
CRC cites American Institute of Physics Handbook (AIPH) table 3f-2 for this value, but in AIPH table 2f-6 there are elastic constants reported that yield 3700,1570, 2620 WEL: 2680: AIPH: 3700: 1570: 2620: Table 2f-6. Calculated from Young's modulus of 147 GPa (lower than commonly accepted for Platinum), Poisson's ratio of 0.39, density of 21370 ...
English: Graph of the speed of sound in water vs temperature. Tabulated values (circle markers) from "The Engineering Toolbox" [1] . Smooth continuous line is a 3rd degree polynomial fit (see below) calculated on the tabulated data, accurate within 0.1%.
The speed of sound at room temperature (20°C) is 343.15 m/s. [4] Using the formula =, we have: Typical female voices range from 1.3 metres (4 ft) to 2 metres (7 ft). Typical male voices range from 2.2 metres (7 ft) to 4 metres (13 ft).
Changes in the speed of sound are primarily caused by changes in the temperature of the ocean, hence the measurement of the travel times is equivalent to a measurement of temperature. A 1 °C (1.8 °F) change in temperature corresponds to about 4 metres per second (13 ft/s) change in sound speed.
Thus speed of sound in gases with higher molar mass have lower speed of sound). -- Jon Ayre 14:20 9th Dec 2005 (GMT) 331.5+0.607*T(degrees celsius) meters/second. -- Monohouse 2006 The linear formula commonly used for the speed of sound as a function of temperature is the first-order approximation of the square root formula.
Comparison of the 1962 US Standard Atmosphere graph of geometric altitude against air density, pressure, the speed of sound and temperature with approximate altitudes of various objects. [ 1 ] The U.S. Standard Atmosphere is a static atmospheric model of how the pressure , temperature , density , and viscosity of the Earth's atmosphere change ...
