They are not related, really. There are many forms of energy that have nothing to do with sound. Heat is a common from of energy that does not make any noise. Electricity is another. Sound is simply a moving wave of high and low pressure areas. Like ocean waves have an amplitude that correspond to the difference in height between the peak and the trough of the wave, sound waves have an amplitude corresponding to the difference between the pressure of the high and low pressure regions. The greater the difference, the greater the amplitude and the greater the intensity of the wave, and the louder the sound. But intensity is not the same as energy and I'm frankly not sure how you determine the "energy" of a noise. Presumably it depends on the intensity, the frequency, and the medium it's traveling through. Anybody else know? You do really measure the sound pressure with a sound pressure level meter. Microphones and eardrums are only sensitive to the sound pressure. Forget the energy if you are listening to music. An other thing is fighting the noise pollution. Only there you need to calculate the power and the energy. Scroll down to related links and look for more on decreasing of sound pressure with distance.

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.
What does the amplitude of a sound wave determine?
Amplitude is the energy of a sound wave, which we also call Loudness
What units are used to measure sound loudness and softness?
Units used to measure loudness are Sone (loudness N) and Phon (loudness level L). Scroll down to related links and look at "Loudness - Wikipedia" and "Sound level change and the change of the respective factor of volume and loudness".
What unit is used to measure sound and loudness?

What is the loudness of a sound?
Loudness of a sound can be measured by a sound pressure level meter. It belongs to psycho acoustics.Loudness is a subjective measure, which is often confused with objective measures of sound prtessure such as decibels or sound intensity. Filters such as A-weighting attempt to adjust sound measurements to correspond to loudness as perceived by the average human. However, as the perception of loudness varies from person to person it cannot be universally measured using any single metric. Loudness is also affected by parameters other than sound pressure, including frequency and duration. In acoustics volume is related to amplitude, sound pressure, and dynamics.There is subjectivly perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).Scroll down to related links and look at "All about loudness".
Are loudness and pitch related?
No, pitch is related to wave frequency, loudness is related to wave amplitude.
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.
What property of sound describes your awareness of the energy of a sound?
loudness
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.
How is amplitued related to loudness?
(amplitude)2 is directly proportional to loudness.
What is the energy of a sound wave most 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.
How is the loudness related to amplitude?
The higher the amplitude the greater is the psychoacoustic feeling of the loudness.
What is meant by the loudness of sound?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength (amplitude). It is a feeling, which is neither the sound pressure as field quantity nor the acoustic intensity as energy quantity. Scroll down to related links and look at "Loudness - Wikipedia".
What is loudness mesured in?
Loudness level LN is measured in phons and the Loudness N is measured in sones. Scroll down to related links and use the fine converter "Loudness level and loudness".
Is the measure of loudness frequency or decibels?
The decibel is a measure of loudness. Frequency is related to pitch.
Is loudness related to the frequency of soundwaves?
No.
The loudness of a sound is related to what?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of sound pressure.
