Do you hate loud typing? Loud eating? Slurping?
You may have a condition known as misophonia.
I can’t stand it when someone behind me at a movie chews popcorn with his or her mouth open. I mean, I really can’t stand it.
I have misophonia, a condition with which certain sounds can drive someone into a burst of rage or disgust. Although only identified and named in the last 20 years, misophonia has been enthusiastically embraced, with websites, Facebook pages and conferences drawing small armies of frustrated visitors.
As a primary care physician, I find that misophonia can present some special challenges: At times, my patients can be the source of annoying sounds. At other times, the condition can be a source of special bonding if I realize that a patient is a fellow sufferer.
....
The range of responses to these noises is broad, from irritation to disgust to anger. Some sufferers even respond with verbal or physical aggression to those making the noises. One woman reported wanting to strangle her boyfriend in response to his chewing.
Researchers are only beginning to understand the science behind misophonia, but early data suggest a hyperconnectivity between the auditory system and the limbic system, a part of the brain responsible for generating emotions. Some studies have found associations between misophonia and other psychiatric conditions, such as obsessive compulsive disorder and post-traumatic stress disorder, but many sufferers appear to have no other major emotional problems. Dr. Schröder and other researchers are developing specific diagnostic criteria.
....
For me, one of the most frustrating aspects of misophonia is what I call the “incredulity factor.” For years, I could not believe that my friends and relatives were not getting as upset at what I considered rude behaviors. They were getting frustrated with me for focusing on sounds they did not really hear.

My god, I thought I was alone. I live in daily rage at the loud typers, slurpers, eaters, etc. It drives me to levels extreme anger to hear that repetitive shit. When I can I wear headphones with music blaring to block it all out.

Your constant whining is driving me bonkers. 
It makes me think about where the clipping is landing. If the clipper is clipping the nails over a wastebasket (ideal), it would still bother me, but not as much as imagining that nail flying onto the rug. or landing on a counter.
Eeeeeks, I'm squirming, just thinking of it.

Yeah, thought about mentioning it in my post, but figured people would take me for a real crazy. But here's the story, anyway.
I had a job that required me to travel. A good-sized expense account allowed me to stay in nice places, but even the nice places have people who miss a few things now and then.
This was one of my first jobs out of college, and I was finding that I didn't like travel all that well. Kind of depressed at being away from my home, I checked into my hotel room and sat down on the bed to make a phone call. I happened to look at a little tray that was next to the bed. It was supposed to have chocolates in it, but instead it had....nail clippings. The previous occupant's nail clippings.
That was it. I called the management, who had someone come and remove the clippings. That was the last night I spent "on the road."

I'm sitting here laughing, able to relate in so many ways, right down to the part where someone thinks you're nuts. In a rare moment that I didn't properly weigh my statements before opening my mouth, I said to my sister, "Everyone in our family has something wrong with their head." Her response was no big surprise, "Well maybe you do!" 
For example, some weeks ago the apartments next to this one were re-doing their paving. In their infinite wisdom, they also felt that they needed to jackhammer out the old (and perfectly nice even compared to our new concrete one) exit ramp instead of just paving on top of it, like they've always done. So, jackhammer noise all day long for several days.
There's a noise site I use often just for relaxation. I hadn't ever used it for sound masking. And yet, when I used the demolition sounds to mask out the industrial noise next door, it worked quite well! It didn't eliminate that noise entirely, but it merged with the site's noise enough that I could tune it out easier. And when they stopped, I often didn't know right away.
And when the neighbors' kid below me starts shrieking, music usually masks it just fine 
(Although earlier this evening I was using the Flying Fortress page to mask the screaming...)
but not to me.

..slurp, snort, cough, rustle, crinkle, crackle, slurp, slurp, CRINKLE, SLUUURRRPP, SNOOORT.
I'm ashamed (kinda') to admit this but I actually stood up once, turned around and told the couple behind me. "You either finish that fuckin' candy bar and your other assorted noises or I'll stick the thing up your asses" That was 12 years ago. I'm nicer now..I wait until the movie is over. 
I live next to a highway. 
But even when I lived in a quiet apartment, I never noticed that sound, and I've had cats for a few decades.
When my boyfriend is eating, I leave the room. He understands 
Gum snapping!!!! DO NOT DO THAT AROUND ME! I once was on a line in a store and the woman behind me snapped gum, maybe only once. I turned around and turned the high beams on her 
such that she sincerely apologized without my saying a word. 
Also, absent minded crushing of water bottles (e.g., the ones used by Poland Spring) that have been made kind of flimsy probably for recycling purposes. They make a crinkly kind of racket when nearly empty and pressure is applied. DON'T DO IT. I WILL GLARE AT YOU, TOO.
Last but by no means least, it is not necessary to POUND THE KEYBOARD and it contributes to Carpal Tunnel Syndrome SO DON'T DO THAT EITHER. 
People randomly whistling in public spaces... If I'm in a supermarket and I hear it, I try to move quickly out of earshot.
It evokes more feelings of irritation in me than anything else. I'm not sure why. I'm almost as irritated by other sounds, like repeated tapping, clicking pens, etc.
People are obnoxious.
Leaf blowers are the worst. And mowers. I cannot stand dance music leaking out of headphones. Don't get me started, LOL!
ear buds might go a long way in reducing frustration with noises that are cluttering, IMO.
I sometimes wear headphones to tune out other members of my family when they talk incessantly or ask stupid questions during a movie or football game. I once left my living room during my alma mater's football game because my MIL wouldn't STFU. She kept her motormouth running with such brilliant comments as repeating the score multiple times in a two minute period, asking if the coaches ever get stressed out, and just endless commentary.
