The sound pressure decreases with distance r in a free field (direct field).
The next question is. How does the sound decrease with increasing distance? After which law?
The sound pressure p diminishes with distance after the 1/r law. Sound pressure decreases inversely as the distance increases with 1/r from the sound source. The Sound pressure level (SPL) decreases by (−)6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.
Sometimes it is said, that the sound decreases with with 1/r², the inverse square law. That is really wrong.
Equations: p2 / p1 = r1 / r2 and p2 = p1 x r1 / r2 or r2 = r1 x p1 / p2
p1 = sound pressure 1 at reference distance r1 from the sound source.
p2 = sound pressure 2 at another distance r2 from the sound source.

What is force times distance divided by time?
force overcome (newtons) * velocity (metres per second) = power (watts)
How far can you travel at 45 mph?
Speed = distance/timeYou have been given the speed and time. You need to find distance. In order to determine the distance, you must rearrange the equation for speed by multiplying both sides of the equation by time, isolating distance. Then plug in your known values and solve for distance.Speed x time = distance47mph x 1/2h = 23.5 mi
Is the cellular respiration process more complex than its equation?
The equation contains the reactions involved, but the actual interactions taking place are complex. The equation is neither...it's just the way it's expressed in writing
What is the importance of the water potential?
Water potential is just like it sounds: the potential for water to move from one place to another. It is generally expressed as an equation, and there are two different types if you're talking about plants or about soils. This is the plant equation: Water potential = osmotic potential + pressure potential + height (usually ignored.) Plants use this to move water on a short term distance. (long term is through the xylem, where tensions, rather than pressures, are used.)
What is the balance Equation of solvay process?
The overall equation is: CaCO3(s) + 2NaCl (aq) Na2CO3(aq) + CaCl2(aq),
What is the equation for converting water from a distance to mass and volume?
There is no such equation, what do you mean by "water from a distance".
What are the three ways to write speed equation to find the time distance and speed?
The basic definition of speed is: speed = distance / time Solve this equation for distance, or solve it for time, to get two additional versions of the equation.
What the equation for speed?
Distance ÷ Time (distance divided by time)
What is the equation for ideal mechanical?
The equation for ideal mechanical advantage is: Output force/input force, Or input distance/ output distance.
Equation to find speed?
Speed = (Distance)/(Time to cover the distance)
Is distance vector or scalar with example equation?
Distance is a scalar. But displacement is a vector.
The equation for speed is?
speed = distance/time
What does the equation distance time defines?

What is the equation used to find the image distance?
To obtain this type of numerical information, it is necessary to use the Mirror Equation . The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows:1/f =1/d0 + 1/d1.
Which equation is used to find average speed?
The equation is Average Speed = Distance Travels/Time. Just answered it Correct!
