"loudness" can be measured using any units of power (energy per time). However most commonly it is measured in decibels (abbreviated dB, a logarithmic scale of power) referenced to the quietest sound a normal human can hear.
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).

The loudness of a sound is measured in decibels, dB. One dB is a just distinguishable increase. Ten dB sounds twice as loud.
A sound level meter will not (usually) measure real sound energy.
It measures dBA, a spectral curve that approximates the hearing sensitivity over the frequency range over which a human being hears.
im not sure what your question but if it is what is the measurement of sound it is decimals
sound frequency of an individual is same . loud means high pitch. soft means low pitch
The loudness or softness of sound is measured in Decibels
The amplitude is related to the loudness of the sound.
there must be air so the force of it makes the woosh sound.
Amplitude of a sound wave is the height between the peak (top most part of the wave) and the trough (bottom most part of the wave).
decibels
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".
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
Amplitude is the energy of a sound wave, which we also call Loudness
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"
Loudness is affected by parameters other than sound pressure, including frequency and duration. also sound wave amplitude
intensity :)
intensity
Volume
It depends on the amplitude.
Amplitude of a sound wave determines LOUDNESS.
vibration remember please i'm your teacher and i know you are in wiki

pleasant sound? softness and low pitch unpleasant sound? loudness and low pitch

Sound has two quantitative qualities that we usually measure and those are amplitude and frequency. So I am asuming you are referring to the loudness and softness as the amplitude quantity. The louder a sound, the more energy it carries. So, a loud sound, using your descriptive terms, has more energy than a soft sound, which has less amplitutde.
Basically it is amplitude.
