Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter.
Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
Sound intensity is a physical quantity that measures the amount of sound energy passing through a unit area, expressed in watts per square meter. Loudness, on the other hand, is a perceptual response to sound intensity and is subjective. In general, as sound intensity increases, the perceived loudness also increases. However, the relationship between intensity and loudness is not linear but follows a logarithmic scale.
Yes the loudness of a sound is called its intensity.
Intensity refers to the amount of energy an sound wave carries, while loudness is the perception of that intensity by the human ear. Intensity is measured in watts per square meter, whereas loudness is measured in decibels. So, while intensity is a physical quantity, loudness is a subjective experience.
Loudness is related to the amplitude of a sound wave. The higher the amplitude of a sound wave, the louder the sound will be perceived by our ears. Amplitude represents the intensity or strength of the sound wave.
My sources tell me that it is in fact legal.

Loudness is really a subjective measure and is often confused with objective measures in decibel units of sound pressure or sound intensity.
Loudness is related to the amplitude of a sound wave. The higher the amplitude of a sound wave, the louder the sound will be perceived by our ears. Amplitude represents the intensity or strength of the sound wave.
If the amplitude of a sound wave increases, the loudness or volume of the sound also increases. This is because amplitude is directly related to the intensity of the sound wave, which our ears perceive as loudness.
Loudness is the colloquial term and intensity is the scientific term. More the intensity higher the loudness. Same way in case of light, higher the intensity of radiation, we call colloquially that as more brightness.

By its amplitude. Really loudness is sound intensity & intensity depends on square of amplitude ie. higher the amplitude higher the intensity which means higher the loudness.
Intensity is the perceived loudness of a sound, which is related to the amplitude of the sound wave. The greater the amplitude, the higher the intensity, resulting in a louder sound. Intensity is typically measured in decibels (dB).
