As far as the sound volume is considered, we perceive a 10x sound intensity as a 2x increase in sound volume. To further understand how loud 50 decibels is, let’s compare them to other noise levels: 60 Decibels. When compared to 60 decibels, 50 decibels will sound twice as loud. In reality, a 60 dB sound is 10 times more intense than a 50 dB ...Sound intensity (or sound pressure) is measured in decibels (dB). To better show how humans perceive sound intensity, the decibel scale is logarithmic.

A dB or decibel is a measuring unit that evaluates the relative power or intensity of sound, generally in contrast with a reference point. It is named after the famous Alexander Graham Bell, who is known for inventing the telephone. dB is a logarithmic unit, which means it displays numerical data of different values, confirming that it is not linear but formed on the power of 10.
