Sound intensity I is a measure in W/m² that is a energy quantity of sound.
Loudness is the quality of a sound that is the primary psychological correlate of physical strength. Better use the sound pressure in pascals (Pa = N/m²) because this sound field quantity makes the effect of moving our ear drums.
Measuring intensity and feeling the loudness does not relate good. Perceived loudness varies from person to person and cannot be measured this way.
A A-weighting filter attempts to adjust sound measurements to correspond to loudness as perceived by the average human.
Units used trying to measure loudness are Sone (loudness N) and Phon (loudness level L).

∙ 14y agoOur ear drums with the ear/brain system are moved only by sound pressure motions. The sound pressure is the effect, but the sound power (sound intensity) of the source is the cause.
The anwer is not so easy like it looks.
Scroll down to related links and look at "Subjectivly perceived loudness ".

∙ 15y agoThe word loudness belongs to psycho acoustics and tells how we feel this sound, that is not measuring the sound like we do with a sound pressure meter. Listening to music means motion to the ear drums. Only sound pressure moves the ear drums. The energy or the sound intensity is much less important here. Sound intensity belongs more to the noise fighters.

∙ 14y agoIn physics, intensity (watts/m²) is a measure of the time-averaged energy flux. The word "intensity" here is not synonymous with "strength", "amplitude", or "level", as it sometimes is in colloquial speech. To find the intensity, take the energy density, that is, the energy per unit volume, and multiply it by the velocity at which the energy is moving. The resulting vector has the units of power divided by area - i.e. W/m². In physics, energy (Joules) is a scalar that describes the amount of work that can be performed by a force, an attribute of objects and systems that is subject to a conservation law. Different forms of energy include kinetic, potential, thermal, gravitational, sound, light, elastic, and electromagnetic energy. The forms of energy are often named after a related force. Any form of energy can be transformed into another form, but the total energy always remains the same.

∙ 8y agoFirst you must understand the concept of power. It refers to the rate at which energy is transferred or converted. The SI unit for energy is the joule; the unit for power is the joule/second, which has the special name watt. Intensity means how concentrated this power is - in other words, power per unit area (of a cross section). The SI units are watts / square meter.In the case of a sound, other things (and especially the frequency) being equal, a more intense sound is perceived as louder.

∙ 10y agoSound intensity is a sound energy quantity. Intensity is very close related to energy.
Sound pressure is a sound field quantity. That is close related to the amplitude.

How does sound travel in solid liquid and in gas . explain?
Sound travels by particles (such as atoms or molecules) bumping into other particles, thus transferring the energy, in form of a sound.
Is a humming sound at the circuit breaker a concern?
No. As the "Related links" explain below, it is normal when you are using copious amounts of electricity.
What is the Difference between sound power level and sound pressure level?
Sound power or sound intensity I is a sound energy quantity.Sound pressure p is a sound field quantity.Sound intensity is sound pressure squared. I = p².See related link.
Sound energy as a carrier of energy?
Yes. Sound energy is a carrier of energy.
What is Vibration of molecules energy called?
Gravitational Energy.
How are light and sound related?
they are related by that light can turn into sound energy
What energy is related yo your eardrum?
Sonic (sound) energy is related to your eardrum.
What is the energy of a sound wave closely related to?
It is most closely related to its amplitude (loudness, magnitude) because this is determined by the energy used to create the sound. Louder noises generally take more energy to create.

It is most closely related to its amplitude (loudness, magnitude) because this is determined by the energy used to create the sound. Louder noises generally take more energy to create.
Is the amount of energy in a sound wave per unit of time and is also related to the loudness of a sound.?
Yes, it is.
Explain how intensity sound and energy are relaxed?
Explain how intensity sound and energy belong together? Answer The frequency tells you the tone pitch, which is a measure of the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. The colloquial word intensity (energy) tells you the loudness of a sound. In reality is meant the sound pressure level SPL of the sound which is no energy.
What is the definition for sound energy?
Acoustic energy is sound energy.The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing.Sound pressure is the effect and sound power (energy) is the cause.But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms. Think of sound pressure level meters (SPL meters).So better ask: What is sound pressure?Have a look at the related links.Note: There are comments associated with this question. See the Discuss:What_is_the_definition_of_sound_energyto add to the conversation. You all are idiotsThe definition of sound energy is energy that is produced by vibrating sound waves. It is a form of energy that is related to a disturbance of matter.
How are waves related to sound energy and seismic energy?
the energy in a wave begins to disperse as it gets farther from the point of origin, this is true for any wave including sound and seismic waves
How does sound travel in solid liquid and in gas . explain?
Sound travels by particles (such as atoms or molecules) bumping into other particles, thus transferring the energy, in form of a sound.
Explain how a speaker makes sound with electrical energy?
It transforms by the air so it get to our ears. I hope this helps!
What is a transformation of energy from a video game console?
It goes from electrical to sound, light, and possibly heat energy
What is the definition of sound volume?
Sound VolumeThe louder a sound, the more energy it has. This means loud sounds have a large amplitude. Think about what an amplifier does: it makes sounds louder. It is the amplitude that relates to how loud sound is.Scroll down to related links and look at "Sound volume".Acoustic energy is sound energy.The definition of sound says that it is a disturbance of energy that comes through matter as a wave, and that humans perceive sound by the sense of hearing.Sound pressure is the effect and sound power (energy) is the cause.Scroll down to related links and look at "Sound pressure and Sound power - Effect and Cause".But our eardrums are only sensitive to the sound pressure, and so are microphone diaphragms.
