The intensity of sound pressure is measured in decibels. dB. Named after Bell the inventor of the telephone, and founder of the Bell Laboratories. This is a ratio, and is a non-SI unit - an associated or derived unit.
One Bel is a sound that sounds twice as loud as another, and equals 10 decibels. Note that as this is named after a person, the 'bel' part is capitalized, e.g. dB.
Loudness is measured in decibels (dB), which quantify the intensity of sound. A sound level meter is typically used to measure loudness, with higher decibel values indicating louder sounds.
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 most common measure used for sound and noise is decibels (dB). Decibels measure the intensity or loudness of a sound, with different levels corresponding to different sounds and their impact on human hearing.

the decibel (dB)
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
decimals
The 'phon' unit is used to measure subjective loudness perception, which is how loud a sound is perceived by the human ear. It is based on the equal loudness contours at different frequencies and is used to quantify the perceived loudness level of a sound.
You can measure the sound pressure with a sound pressure level (SPL) meter. Loudness ist a psycho acoustical sensation.

it is a respect for our culture and nation :)
