Loudness is a subjective perception of each individual. Your neighbor's music is loud, but yours played at the same volume is not.

Subjective - but hardly a scientific answer. Assuming both pieces are played at the same power output from identical equipment, their intensities and loudness will obviously be the same. "Loudness" is a function of the human hearing's frequency response, not a measure of how to annoy your neighbours.

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".
There are the loudness level LN in phons and the loudness N in sonesScroll down to related links and look for more on correlation between sones and phons.
The quality or state of being loud.
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.
No, a drawing of an atom is not a scientific definition. A scientific definition of an atom would describe it as the smallest unit of matter that retains the properties of an element.

The unit of relative loudness is the sone. The unit for absolute loudness, or loudness level, is the phon. Both relative and absolute loudness are perceptual measures that vary from person to person.The unit used to measure sound pressure is the dB (decibel). Since dB measures the power of a sound wave, a physical characteristic, it is not a perceptual measure but a scientific one (thus perception of the sound has no effect on it).Read more: What_is_the_unit_of_relative_loudness
