Loudness is usually described in decibels, which is a logarithmic scale based on sound pressure level. If the threshold of hearing (for healthy ears) is taken as 2 x 10-5 Pascals, and this is called 0 db, then a fairly normal level such as you would find in a room in a house with the TV on is a sound pressure level 1000 times greater, ie 2 x 10-2 Pascals, and on the db scale this will be 60 db. Recommended maximum level for working is usually 90 db, above this ear defenders should be used.
See the Wikipedia article on 'Decibel'
(1 Pascal is 1 Newton per sq meter)
There are no normal or abnormal decibels. Decibels mean a ratio. For more about "decibels" look at the related links.
Loudness level LN is measured in phons and the Loudness N is measured in sones. Scroll down to related links and use the fine converter "Loudness level and loudness".
You can convert the loudness in sones to the loudness level in phons. 4 sones equals 60 phons. Scroll down to related links and read "Correlation between sones und phons".
Decibels can compare loudness
yes it is a unit of loudness
Loudness depends on the amplitude. square of amplitude is proportional to the loudness. Pitch is decided by the frequency. One can sing at higher pitch but at lower voice.
A normal conversation has a loudness (decibels level) of about 60 dB. As iy approached 70 dB it would be come loud.
68 decibels is the loudness of normal conversation, or perhaps a piano played gently.
Loudness level LN is measured in phons and the Loudness N is measured in sones. Scroll down to related links and use the fine converter "Loudness level and 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"
