The most annoying sound.. Short answers please!

Yup, no random calls on my home phone anymore since I got rid and mobile is on silent.  Bliss.

All of the above! Doorbell and home phone were the worst, removed doorbell, and home phone no longer works! Aaaah.

Other people eating/chewing. Fork scrape in a plate. Anything loud and piercing like a squeal or siren. 

Another one. The noise of a bus letting air out suddenly. At least that’s what I think it’s doing. Loud, sudden and unexpected. A recipe for displeasure.

are you calling us whinning?  <--joke

Whining kids

and making those memories even stronger

though it might have practical application, if you manage to tie them to something you're easily forgetting,

I do forget names in about a week if I do not use them, especiallty those with few lettes

I used to adress one women with a name Judy for 2 months - ''hello Lucy, how are you?''. another workmate told me to stop calling her wrong name unless I want to be lynched LOL

Number 1 for me is people eating, especially with their mouths open or chewing... Argh it's like I can still hear the sound now. 

Then it's knife and forks scraping the plate.

The underground tube noises.

Chair scraping the floor.

Water pouring into a jar... Argh writing this is making me hear them all! 

Car Horns; I automatically assume it's due to me.

hedge trimmers.

nightmare wake up ringtone in a city

everytime I planned to sleep longer

you should bash parent's heads, it's their fault

Babies crying. Literally evokes this deep instinctual feeling in me to want to pick the child up and bash it against something until it stops.

Don't worry, I don't have kids.

Cheery whistling.

ice cream van chimes: the most desolate, ennui inducing sound ever at a distance and horrifically deafening up close. 

Aggressively ringing phones - especially old school ones. 

Taps dripping.

Engines running whilst stationary.

Loud cars, especially with deep engine noise.

Petrol strimmers/ hedge trimmers.

Leaf blower

Car/Home alarms unnecessarily going off

a loading door "alert" 

Electric Car/Lorry in reverse

Appliance finishing or plug being turned on

Smoke alarm battery dying... in the next door flat and they're on holiday

scraping the floor with a chair during classes at school

scraping styrofoam

whistles (like those used by PE teachers)

that one makes me go mad - breathing over my ear

People when they blow on something.....goes right through me

alarms

People whistling 

My tinnitus - like a dentist's drill.
