Edit: Wow "Please don't be surprised if I pull out my computer at dinner and begin handling some of my email. I have difficulty hearing when there is noise; at dinner, when people are speaking to each other, I usually cannot hear their words. Rather than feel bored, or impose on everyone by asking them to speak slowly at me, I do some work."
Auditory confusion: This can occur when there is difficulty locating and isolating individual sounds in an environment where there are multiple sources of conflicting noise. “Cocktail party deafness” is one example of auditory confusion when background noise competes with foreground.
Auditory stimulus bound effect: Stimulus bound effect describes the ability to ignore irrelevant auditory stimuli in the immediate environment. Individuals who suffer from stimulus bound effect are easily distracted by irrelevant auditory stimuli.
The radio is the worst. If I read lyrics I can get them memorized or sing along no problem. But I can hear a song 100 times and still not know many of the words. It still amazes me that people can actually hear all the words and make them out while I have absolutely no trouble remembering the notes/instrumentation etc...
