How is sound pressure converted to sound power level?
Sound power level is equal to sound pressure level and intensity level at a distance of r = 0.2821 m from the source at full sphere propagation. See related Link.
Calculate sound power level given sound pressure level?
Compare Sound power, Sound pressure, and Sound intensity. All share as level the same unit of measure: the decibel (dB). The term "sound level" is commonly substituted for each. As characteristic impedance of air we use the round value Z = 400 N·s/m³ (Pa·s/m). Then the "sound level", that is the sound pressure level Lp and the sound intensity level LI is exactly the same as a decibel value. The sound power or acoustic power is the sound energy constantly transferred per second from the sound source. A sound source has a given constant sound power that does not change if it is placed in a different room environment. Sound power is a theoretical value that is not measurable. It is calculated and expressed in watts and as sound power level LW in decibels. A sound source produces sound power and this generates a sound pressure fluctuation in the air. Sound power is the distance independent cause of this, whereas sound pressure is the distant-dependent effect.
What is the different between devices and appliances?
The most probable difference between the two: 1. Device - does not consume power 2. Appliance - consumes power
What is the Difference between 12 volt and 18 volt drills?
12 volts is less of power than 18 volts drill
What is the difference between vo2 max and pvo2 max?
pVO2 max = power at VO2 max. I think it's the power output (in watts) that is generated while cycling at VO2 max
What is the difference between a commercial and a regular microwave?
The commerical microwave has more power then a regular microwave which has a smaller level of power.
How do you know the difference between the high pressure power steering line and the low pressure line on a 1998 Mercury Mountaineer?
High pressure line gets very hot.
What is the difference between a Acura Integra ls and a ls special?
Trim level such as the interior, power windows seats ect.
What the difference between process piping and power piping?
What the difference between process piping and power piping?
How is sound pressure converted to sound power level?

In the water analogy of an electric circuit what corresponds to the power supply the resistor and potential difference?
Power supply: Water pump, producing pressure at its output valve.Resistor: A section of pipe. Flow of water loses energy on the way through, due to friction with the pipe's interior wall.Potential difference: Difference in water pressure between the beginning and end of the pipe section.
What is suction power?
A force over an area produced by a pressure difference
What is the difference between the power lines phase 1 level 6 and the power lines 2 phase 7?
Helpful. What you call "power lines 1 level 6", it has to make 10 and there are six powercells. What you call "power lines 2 level 7" is has to make 21 and there are more than six which is 9 powerce.
What is the difference between power and current?
It's the difference between pressure and flow. The pressure is measured in volts, and the current in amps.Current is the flow of electrons.Power=VIcosϕV=voltageI=currentCosϕ=cosine of angle between V and IAnswerCurrent is a drift of electric charge, expressed in amperes. Power is the rate of doing work, expressed in watts (equivalent to a joule per second).
What is the major difference between the political parties and the pressure groups?
The objective of political parties is to attain power and form the government, whereas the aim of pressure groups is only to influence the decision-making of the government
What is the difference between the resolving power and the magnifying power?
help!
Does a height of a dam make a difference on the amount of energy the dam produce?
Yes. The height of the water level above the turbine affects the water pressure, and therefore the amount of power that can be generated.
