Sound Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.
Barometric Pressure - Barometric Pressure is the pressure on earth that is caused by the weight of the air above us. It is sometimes the atmospheric pressure. It should be entered in millibar.

STEP 1: Convert Input(s) to Base Unit

Atmospheric Pressure: 101325 Pascal --> 101325 Pascal No Conversion Required
Barometric Pressure: 6921.213 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p = P_atm-P_b --> 101325-6921.213

Evaluating ... ...

p = 94403.787

STEP 3: Convert Result to Output's Unit

94403.787 Pascal --> No Conversion Required

FINAL ANSWER

94403.787 ≈ 94403.79 Pascal <-- Pressure

Total Atmospheric Pressure given Sound Pressure

Go Atmospheric Pressure = Pressure+Barometric Pressure

Barometric Pressure given Sound Pressure

Go Barometric Pressure = Atmospheric Pressure-Pressure

Sound Pressure

Go Pressure = Atmospheric Pressure-Barometric Pressure

Sound Pressure Level in Decibels (Root Mean Square Pressure)

Go Sound Pressure Level = 20*log10(Pressure RMS/20)

Sound Pressure Formula

Pressure = Atmospheric Pressure-Barometric Pressure
p = 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 = Atmospheric Pressure-Barometric Pressure to calculate the Pressure, The Sound Pressure is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal. Pressure is denoted by p symbol.

How to calculate Sound Pressure using this online calculator? To use this online calculator for Sound Pressure, enter Atmospheric Pressure (P_atm) & Barometric Pressure (P_b) and hit the calculate button. Here is how the Sound Pressure calculation can be explained with given input values -> 94403.79 = 101325-6921.213.

FAQ

What is Sound Pressure?

The Sound Pressure is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal and is represented as p = P_atm-P_b or Pressure = Atmospheric Pressure-Barometric Pressure. Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth & Barometric Pressure is the pressure on earth that is caused by the weight of the air above us. It is sometimes the atmospheric pressure. It should be entered in millibar.

How to calculate Sound Pressure?

The Sound Pressure is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave. In air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal is calculated using Pressure = Atmospheric Pressure-Barometric Pressure. To calculate Sound Pressure, you need Atmospheric Pressure (P_atm) & Barometric Pressure (P_b).
