Is there a problem?
Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of hearing).
Reference sound pressure level Lpo = 0 dB-SPL (Threshold of hearing level).
Get sound pressure p when entering sound pressure level Lp = 92 decibel (dB).
Sound pressure p = po×10^(Lp/20) Pa (= N/m²) = 2×10^−5×10^(92/20) Pa = 0.796 Pa.
What else can I help you with?
A vacuum cleaner produces sound with a measured sound level of 64.0 dB. What is the pressure amplitude of the sound mPa?
Sound level Lp = 64 dBSPL equals what sound pressure p (rms)? The sound pressure is: 0.0317 pascals (Pa) = 31.7 millipascals (mPa) The reference sound pressure is: p0 = 20 μPa = 2 · 10-5 Pa (0 dB) The "sound pressure amplitude" is 1.414 larger than the rms value of the sound pressure, that means 44.8 mPa. Amplitude means always the peak value. There is an easy to use calculator. Scroll down to related links and look at "Conversion of sound units (levels)".
What is the difference between sound pressure and sound power, and how do they relate to each other in the context of acoustics?
Sound pressure refers to the force exerted by sound waves on a surface, measured in units like pascals. Sound power, on the other hand, is the total energy output of a sound source, measured in watts. In acoustics, sound pressure is directly related to sound power, as the intensity of sound waves determines the pressure they exert. Sound power is the source of sound pressure, with higher power leading to higher pressure levels.
What determines the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
How many decibels in a pascal?
1 pascal (Pa) is equivalent to 94 dBSPL. Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of hearing) Reference sound pressure level Lpo = 0 dB-SPL (Threshold of hearing level) Get sound pressure level Lp in dB when entering sound pressure p = 1 Pa: Lp = 20×log (p / po) dB = 20×log (1 / 2×10^−5) = 20×log (1 / 0.00002) = 20×log (50000) = 94 dB.
What measures the loundness of sound?
You cannot "measure" the subjective loudness feeling in decibel with a "dB"-meter. You can measure the objective sound pressure with a "sound pressure meter" that shows the sound pressure in pascals or the sound pressure level SPL in dB or dBA.
What is the unit for the for the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
What is the gadget to measure sound volume?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).

What unit is used to measure volume in science and how loud is it?
Take a sound pressure level meter (SPL meter). Try to measure the sound pressure p in pascals or in decibels.

What is larger atmospheric pressure or sound pressure?
Atmospheric pressure is typically larger than sound pressure. Sound pressure levels are typically measured in decibels (dB) and represent fluctuations in air pressure caused by sound waves. Atmospheric pressure, on the other hand, is the pressure exerted by the weight of the atmosphere on the Earth's surface, which is typically higher than sound pressure levels.
Human ear is sensite to sound intensity ranging in db min and max?
That is not correct. The human ear drums are only sensitive to the sound pressure variations. Also the microphone diaphragms are moved by the amplitude of sound pressure variations. At 0 dBSPL, the threshold of hearing, the sound pressure is 20 micropascals. At 134 dBSPL, the threshold of pain, the sound pressure is 100 pascals.
What determines the volume of sound?
The volume of a sound is measured by the sound pressure in pascals or newtons per square meter. The sound pressure level is measured by a sound pressure level meter (SPL meter).
How is an ear like a microphone?
The microphone has a diaphragm that is moved by the sound pressure of the sound waves. This sound pressure, measured in pascals, is converted by the microphone to the electric audio wave. Our auditory system has two ear drums that are similar to the microphone's diaphragm that delivers the sound wave to the inner ear. Only sound pressure (pascals) is moving the ear drums. Sound intensity (power) has nothing to do with this.
How many decibels in a pascal?
1 pascal (Pa) is equivalent to 94 dBSPL. Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of hearing) Reference sound pressure level Lpo = 0 dB-SPL (Threshold of hearing level) Get sound pressure level Lp in dB when entering sound pressure p = 1 Pa: Lp = 20×log (p / po) dB = 20×log (1 / 2×10^−5) = 20×log (1 / 0.00002) = 20×log (50000) = 94 dB.
Human ear is sensite to sound intensity ranging from db?
The human is is not sensitive to sound intensity (energy), but the human ear is sensitive to sound pressure or to sound pressure level (SPL). It is ranging from 20 micropascals to 150 pascals, that is a SPL of 0 dB (threshold of hearing) to 137.5 dB (threshold of pain).
