Loudness and the Decibel Scale. Another property of sound or noise is its
loudness. A loud noise usually has a larger pressure variation and a weak one
The decibel scale is a reflection of the logarithmic response of the human ear to
... The sound intensity in decibels above the standard threshold of hearing is ...
We often use this logarithmic scale to describe the intensity of sound.
Jun 10, 2016 ... You have to think about the decibel scale very carefully, because it's a
logarithmic scale and it works in a different way to the scale on a ruler, ...
A readable explanation of the decibel scale (dB scale), including dBA and dBC.
Also phons and sones, noise units for measuring loudness.
A decibel dB(A) is a unit of measurement that indicates how loud a sound is.
Humans can hear sounds between 0 and 140 decibels.
A unit of a logarithmic scale of power or intensity called the power level or
intensity level. The decibel is defined as one tenth of a bel where one bel
represents a ...
