Adobe Audition CC: Explaining Amplitude Statistics
There are 16 different measurements in this window, with four that are truly important.

Possibly Clipped Samples. This should always be 0. Any other number means that your audio is too loud and, most likely, distorted.

For me, this is the most essential measurement. I don’t release any audio that has the potential to be distorted.

Peak Amplitude (and its cousin: True Peak Amplitude). This measures the loudest portion of your clip. This should be any number smaller than 0 dB.

I used to look exclusively at this number, but I’ve learned that peak values are deceptive. I generally want my peaks between -6 and -3 dB. Also, click the small “home base” shaped icon to jump to that portion of your clip with the loudest peak. This simplifies fixing a problem.

ITU-R Loudness. This measures the average level of your clip. It is much more representative of the volume of your clip than peaks. After distortion, this is the most important reading.

For the web, I want this ±1 of -16 LUFS. Most of my mixes end up around -16.5 to -17 LUFS. (1 LUFS is, essentially, 1 dB.)

NOTE: Broadcast and cable require average levels closer to -24 LUFS. The web isn’t that restrictive.

Using Visual Loudness for Better Wayfinding | Viget
Well-designed interactive experiences use loudness to help identify and amplify wayfinding systems. Because, if everything screams all you will hear is noise. Emphasis used properly—like a loudspeaker in a crowded room—can help guide attention more effectively. Careful use of visual loudness helps illuminate priority.
