The auditory threshold is used as the reference sound pressure p0 = 20 µPa = 2 × 10 −5 Pa. The threshold of hearing corresponds to the sound pressure level Lp = 0 dB at f = 1 kHz. Sound intensity I as Sound energy quantity: The auditory threshold is calculated as the reference sound intensity I0 = 10 −12 W/m 2.

If the sound pressure from a rifle shot is measured to 134 dB at 1.25 feet - the reduction in sound pressure level at distance 80 feet can be calculated as dL = 20 log ((80 ft) / (1.25 ft)) = 36 dB Sound Pressure (p) is the difference between the pressure caused by a sound wave and the ambient pressure of the medium the sound wave is passing through. The Sound Pressure Level (SPL) in decibels = 20 x the logarithm of the ratio of the sound pressure to the reference sound pressure … 2019-10-15 Our sound pressure example is typical of all root power quantities (sound field) calculations.

Sound intensity I as Sound energy quantity: The auditory threshold is calculated as the reference sound intensity I0 = 10 −12 W/m 2. Sound level SPL, pressure, pascal, and intensity level (SIL) conversion: Speed of sound in air and the significant temperature calculation: Table of sound pressure levels − Sound pressure and intensity: Speed of sound (velocity of sound) in humid air calculation: Microphone sensitivity conversion dB re 1 V/Pa − Transfer factor mV/Pa Reference sound pressure p 0 = 20 μPa = 2 × 10-5 Pa ≡ 0 dB Field sizes as the sound pressure, will always be shown as RMS value. The sound pressure p is the sound pressure that is specified as an rms value and of the static pressure p St (air pressure) of the surrounding air is superimposed. p total = p St + p Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave.In air, sound pressure can be measured using a microphone, and in water with a hydrophone. Sound Pressure Level is easier to measure compared to Sound Power Level, which explains why NVH requirements of electrical machines are sometimes given in Sound Pressure Level.

PSI is the most common standard to measure pressure.
