There is no sound pressure, there is atmospheric pressure of 101.325 kPa equivalent to 760 mmHg (torr), 29.92 inHg or 14.696 PSI. The sound pressure is the local pressure deviation from the ambient atmospheric pressure caused by a sound wave.
No, sea-level pressure and station pressure are not the same. Station pressure is the atmospheric pressure measured at a specific location, while sea-level pressure is the station pressure adjusted to sea level using a standard formula to account for differences in elevation.
No, station pressure represents the actual atmospheric pressure at a specific location, while sea level pressure is adjusted for elevation. Sea level pressure can be higher than station pressure due to the effect of elevation on atmospheric pressure, but station pressure cannot exceed sea level pressure.
Station Pressure is the actual pressure the station records, however this isn't really used in meteorology as there is no comparsion due to elevation, therefore for a synoptic look, Station Pressure is converted to Sea Level Pressure.
The air pressure at sea level is typically around 1013 millibars or 29.92 inches of mercury.
Surface pressure is simply the air pressure at ground level, anywhere on Earth. Sea level pressure is an adjustment made so that we can compare pressure at stations of different elevations. Sea level pressure is surface pressure if it were taken at sea level. Small differences in air pressure are important in meteorology, which is why we measure pressure precisely. The problem is that pressure is a function of elevation to first order, and weather differences to second. That's why it must be adjusted to be meaningful. Otherwise we would think that Denver, CO is always under an extreme low pressure system.
Sea level pressure, sometimes as mean sea level pressure.
Do you mean speed of sound at sea level? Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".
The speed of sound has nothing to do with the sound pressure, like "at sea level" or on top of a mountain. But the speed of sound has very much to do with temperature. Scroll down to related links and look at "Calculation of the Speed of Sound".
The velocity of sound in air at sea level at normal temperature and pressure is 3.4329 metres/second.
Sea level pressure.
No, sea-level pressure and station pressure are not the same. Station pressure is the atmospheric pressure measured at a specific location, while sea-level pressure is the station pressure adjusted to sea level using a standard formula to account for differences in elevation.
the atmospheric pressure below sea level is highter (novanet)
Speed of sound in air is dependent on the air pressure, and air pressure is dependent on height above sea level. Up high, pressure is lower and speed of sound is different.
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.
The speed of sound has neither to do with the sea level nor with Tucson. Speed of sound has mainly to do with the temperature of the air. Look at the link: "Speed of Sound in Air and the effective Temperature".
The answer is sea level. Because atmospheric pressure decreases when altitude increases
It is greater.
