Decibels are a measurement of the loudness of sound.
Sound is measured in units called decibels (dB). Decibels quantify the intensity or loudness of sound and are used to compare different levels of sound from quiet to loud.
As decibels increase, the volume of sound also increases. Decibels is a unit to measure the intensity of sound, so a higher decibel level indicates a louder sound.
Loudness or sound level is measured in units called decibels (dB).
Decibels
The loudness or volume of music is measured in decibels. Decibels are a unit used to quantify the intensity of sound.
An increase of 10 decibels represents a doubling of sound intensity. So, 10 decibels louder would sound noticeably louder, such as a car passing nearby compared to a quiet conversation.
