Sound Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure = Total Atmospheric Pressure-Barometric Pressure
P_s = P_atm-P_b
This formula uses 3 Variables

Variables Used

Pressure - (Measured in Pascal) - The Pressure refers to the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Total Atmospheric Pressure - (Measured in Pascal) - The Total atmospheric pressure refers to the force exerted by the weight of the atmosphere on a surface, typically measured in pascals (Pa) or atmospheres (atm), at sea level averaging 101,325 Pa.
Barometric Pressure - (Measured in Pascal) - The Barometric Pressure refers to the force exerted by the atmosphere at a given point, measured using a barometer, typically in inches of mercury in (Hg) or (mb).

STEP 1: Convert Input(s) to Base Unit

Total Atmospheric Pressure: 101325 Pascal --> 101325 Pascal No Conversion Required
Barometric Pressure: 100525 Pascal --> 100525 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_s = P_atm-P_b --> 101325-100525

Evaluating ... ...

P_s = 800

STEP 3: Convert Result to Output's Unit

800 Pascal --> No Conversion Required

FINAL ANSWER

800 Pascal <-- Pressure

Sound Pressure Level in Decibels (Root Mean Square Pressure)

Go Sound Level in Decibels = 20*log10(Pressure RMS in Micropascal/(20*10^(-6)))

Total Atmospheric Pressure given Sound Pressure

Go Total Atmospheric Pressure = Pressure+Barometric Pressure

Barometric Pressure given Sound Pressure

Go Barometric Pressure = Total Atmospheric Pressure-Pressure

Sound Pressure

Go Pressure = Total Atmospheric Pressure-Barometric Pressure

Sound Pressure Formula

Pressure = Total Atmospheric Pressure-Barometric Pressure
P_s = P_atm-P_b

What is Barometric Pressure?

Barometric Pressure is the pressure caused by the weight of the air above us. The barometric pressure also varies based on altitude.

How to Calculate Sound Pressure?

Sound Pressure calculator uses Pressure = Total Atmospheric Pressure-Barometric Pressure to calculate the Pressure, The Sound Pressure formula is defined as the local variation from the ambient atmospheric pressure caused by a sound wave, typically measured in pascals (Pa). Pressure is denoted by P_s symbol.

Here is how the Sound Pressure calculation can be explained with given input values -> 94403.79 = 101325-100525.

FAQ

What is Sound Pressure?

The Sound Pressure formula is defined as the local variation from the ambient atmospheric pressure caused by a sound wave, typically measured in pascals (Pa) and is represented as P_s = P_atm-P_b or Pressure = Total Atmospheric Pressure-Barometric Pressure. The Total atmospheric pressure refers to the force exerted by the weight of the atmosphere on a surface, typically measured in pascals (Pa) or atmospheres (atm), at sea level averaging 101,325 Pa & The Barometric Pressure refers to the force exerted by the atmosphere at a given point, measured using a barometer, typically in inches of mercury in (Hg) or (mb).

How to calculate Sound Pressure?

The Sound Pressure formula is defined as the local variation from the ambient atmospheric pressure caused by a sound wave, typically measured in pascals (Pa) is calculated using Pressure = Total Atmospheric Pressure-Barometric Pressure. To calculate Sound Pressure, you need Total Atmospheric Pressure (P_atm) & Barometric Pressure (P_b). With our tool, you need to enter the respective value for Total Atmospheric Pressure & Barometric Pressure and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
