When you are talking you send your sound pressure, but around you is the atmospheric pressure and your waves are on top of that. You are changing a bit but not noticable that nearly static air pressure. http://en.wikipedia.org/wiki/Atmospheric_pressure
Internal Static Pressure, as it pertains to HVAC AHU's: it is the static pressure losses, which the fan needs to overcome to create a certain amount of CFM flow through the unit. It may or may not include those losses created by the filter boxes, dampers, louvers, etc. All other static pressure losses not considered internal can be notes as ESP (External Static Pressure). The absolute value of the sum of the ESP and ISP is referred to as Total Static Pressure (TSP), which is the pressure that the fan will have to overcome to generate the rated CFM.
The main difference of static pressure and dynamic pressure is:- static pressure is exerted by fluid at rest but dynamic pressure is pressure exerted by fluid in motion.
for fresh air static pressure it shoul be high are low
Static pressure certainly does affect flow rate. Static pressure can slow or speed up flow rate based on the liquid.
By grounding.
it works with the difference between pitot pressure and static pressure

For a gas it is the value of u+pv where u=internal energy p=pressure v=volume

No, it is not static
for fresh air static pressure it shoul be high are low
what is 99'' of static pressure equal to in hg(mercury)
Static pressure certainly does affect flow rate. Static pressure can slow or speed up flow rate based on the liquid.
Static pressure can be caalculated by simply measuring the height of the faucet from the highest fixture above this faucet and times the height by .434 for static pressure
The CFM of the equipment are given, how to calculate Static Pressure for it.
As your static pressure increases your Amp draw will drop
absolute pressure
