Overpressure given Sound Pressure Level in Decibels Calculator

Overpressure - (Measured in Pascal) - Overpressure for a charge exploded on the ground surface.
Sound Pressure Level - (Measured in Decibel) - Sound Pressure Level is the pressure level of a sound, measured in decibels.

STEP 1: Convert Input(s) to Base Unit

Sound Pressure Level: 25 Decibel --> 25 Decibel No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (dB)^(1/0.084)*(6.95*10^(-28)) --> (25)^(1/0.084)*(6.95*10^(-28))

Evaluating ... ...

P = 3.04879178090486E-11

STEP 3: Convert Result to Output's Unit

3.04879178090486E-11 Pascal -->3.04879178090486E-14 Kilopascal (Check conversion here)

FINAL ANSWER

3.04879178090486E-14 ≈ 3E-14 Kilopascal <-- Overpressure

< 17 Parameters of Vibration Control in Blasting Calculators

Burden Suggested in Langefors' Formula

Go Burden in Langefors' Formula = (Diameter of Drill Bit/33)*sqrt((Degree of Packing*Weight Strength of Explosive)/(Rock Constant*Degree of Fraction*Ratio of Spacing to Burden))

Frequency of Vibration given Acceleration of Particles

Go Frequency of Vibration = sqrt(Acceleration of Particles/(4*(pi)^2*Amplitude of Vibration))

Burden Suggested in Konya Formula

Go Burden = (3.15*Diameter of Explosive)*(Specific Gravity of Explosive/Specific Gravity of Rock)^(1/3)

Amplitude of Vibrations given Acceleration of Particles

Go Amplitude of Vibration = (Acceleration of Particles/(4*(pi*Frequency of Vibration)^2))

Distance from Explosion to Exposure given Overpressure

Go Distance from Explosion to Exposure = ((226.62/Overpressure))^(1/1.407)*(Maximum Weight of Explosives per Delay)^(1/3)

Overpressure due to Charge Exploded on Ground Surface

Go Overpressure = 226.62*((Maximum Weight of Explosives per Delay)^(1/3)/Distance from Explosion to Exposure)^(1.407)

Amplitude of Vibrations using Velocity of Particle

Go Amplitude of Vibration = (Velocity of Particle/(2*pi*Frequency of Vibration))

Frequency of Vibration given Velocity of Particle

Go Frequency of Vibration = (Velocity of Particle/(2*pi*Amplitude of Vibration))

Frequency of Vibrations caused by Blasting

Go Frequency of Vibration = (Velocity of Vibration/Wavelength of Vibration)

Burden given Stemming at Top of Borehole
