In what unit is the loudness, or intensity, of sound commonly measured?

Explanation

The loudness, or intensity, of sound is commonly measured in decibels, a logarithmic unit that reflects how the human ear perceives changes in sound intensity. Because the scale is logarithmic, a relatively small increase in decibel level actually represents a much larger increase in actual sound energy. Prolonged exposure to sounds above roughly 85 decibels, such as loud machinery or concerts, can gradually damage hearing over time. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
