Fuel stations which insist on having all pumps beep at a very high pitch at every user prompt, or at times for no apparent reason.
Get six or seven people within aural proximity filling their vehicles with fuel and this very well can push me over the edge at certain stations.
repetitive sneezing, coughing... I feel terrible about this, and my close family even apologizes when they sneeze or cough more than once because of me. I am getting better with this, however I see no use for certain gas stations that beep... I mean what population of people does this beeping benefit? Is the benefit to this population worth the risk of annoying the hell out of the consumer? I am even trying to think about neurotypical folks here as well, I find it hard to believe that they are not at least somewhat aggravated or annoyed by this sonic belligerence.
Certain types of chewing by certain people. Lets not forget those few folks that decide to open up cokes and start munching on kettle fried chips during meetings / presentations during utter silence.
Further to the above point, if people are being hyper-cognizant about the volume of their chewing or eating behaviors it annoys me even more. Or even other behaviors such covering ones mouth with their hands during conversations at lunch. I mean if they were speaking with their mouth full I probably wouldn't notice, however by drawing my attention to their mouth by covering it with their hands increases the likelihood of me actually seeing them speak with their mouth full (which I assume is what they are trying to prevent in the first place).
Oddly enough banging electronic music, with repetitive hooks, beats, melodies, stabs, clicks, pops, beeps etc. are completely soothing and energizing to me. When I first heard a hard 4/4 time dance track I thought "This is the shixt that goes on in my head all the time anyway; its great that there is an entire genre that is dedicated and is constantly evolving from such repetition".
