We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels. “We are still close friends and I would not change that for anything! For example, infrared and visible energy from the Sun impinge on Earth at an intensity of 1300 W/m 2 just above the atmosphere. Water is much more dense than air, so the standard pressure is different. This unit is seldom used, however, because the human ear is very sensitive. She was born in Norwalk, Connecticut, and was a competitive dancer for over 10 years before starting her social media career. I hear people say "decibel" for sound intensity, but a dB is just the ratio between two sound intensity levels, so it's really not a unit. It determines the loudness of a wave that we feel. The resulting vector has the units of power divided by area (i.e., surface power density). 1 : the quality or state of being intense especially : extreme degree of strength, force, energy, or feeling. Thus, we define the relative sound intensity level as SL(dB) =10log I Io The unit of SL is called the decibel (abbreviated dB).
