Suppose we have two unrelated sound sources of unequal SPLs (e.g. 80 and 74 dB SPL. Using the above procedure we can show that the two intensities are 10-4 and 2.5x10-5 W/m 2 respectively. If we add these together we get 1.25x10-4 W/m 2 which if we convert back to decibels gives us approximately 81 dB SPL.

Intensity level is measured in dB. See @Vintage answer. Secondly, they are not measures of loudness. Loudness is measured in phons, and is equal to the sound intensity level (SIL) at a frequency of 1000 Hz.Thus, the intensity level is the comparison of one intensity to another and may be expressed: Intensity level = 10 log 10 (I 1 /I 0) (dB) For instance, the difference between intensities of 10-8 watts/m 2 and 10-4 watts/m 2, an actual difference of 10,000 units, can be expressed as a difference of 4 bels or 40 decibels.Sound Intensity. Rate of energy flow across a unit area (power per unit area). Sound Intensity Level (IL) = , where watts/meter. In a free field, intensity varies as for an omni-directional source. This corresponds to a 6 dB decrease in intensity for each doubling of distance from the source.Elin grabbed my scarf as I struggled to my feet.
