belli and decibelli
Decibels measure loudness by quantifying the intensity of sound waves. The higher the decibel level, the louder the sound.
You can measure the sound pressure with a sound pressure level (SPL) meter. Loudness ist a psycho acoustical sensation.
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".
The loudness of sound is determined by the amplitude of the sound wave. A larger amplitude produces a louder sound. Decibels (dB) are used to measure loudness on a logarithmic scale.
The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.

The loudness of sound is also known as the sound intensity, which refers to the measure of the energy carried by sound waves. It is perceived by humans as how loud or soft a sound is. The unit used to measure sound intensity is decibels (dB).
The loudness of sound is determined by the amplitude or intensity of the sound wave. Greater amplitude or intensity results in a louder sound. The unit used to measure loudness is decibels (dB).
The measure of the loudness or intensity of sound is called decibels (dB). It quantifies the level of sound pressure that is perceived by the human ear. The higher the decibel level, the louder the sound.

Feelings of loudness are different from person to person. So don't talk of "measuring" the "loudness".For psycho acoustic values we have units to express loudness:Sone (loudness N) and Phon (loudness level L).You can really measure the sound pressure with a sound pressure level meter. That is measured in dB SPL. Loudness is a subjective measure but sound pressure is an objective measure. But that is different. Don't mix it up.
