Uhhhhhh
The most annoying sound I have ever hated since I was born is when someone is scratching a plate with a fork like this
while they are eating.
And guess what? There is a much worse!
When someone takes the bite off of a fork with their teeth and it makes a sound 
Toaster popping.
I can’t even put what one specific sound I hate most because I have hypersensitivity to stimuli so like…I hate TONS of different sounds…some ones I’ve always hated even before my hypersensitivity though are people chewing w their mouths open, or bones being popped like when people crack their knuckles.
My actual favorite sound that I really like I think is rain. I love the sound of storms, of rain on the roof of a car (so long as I’m not driving lol), maybe just falling water in general. When I was little I found the sound of the shower very soothing and would curl up on the laundry basket in the bathroom while my mom showered and take a nap.
Here’s mine.
I hate the sound of vacuum cleaners
And my mum does it every single day 
The faint sound of the geese migrating way high up in the sky at night.
There is this door near where I like to sit at the clubhouse. It makes the most obnoxious squeaking sound when people go through it. Metal rubbing against dry wood. It’s driving me crazy.
hahaha love that movie
I LOVE the sound of leaves rattling in the wind.
I strongly dislike the sound of… I don’t know, I can’t think of anything.
I love thunder and lightning! Birds singing on a cold spring day. Or that sad sounding lonely night bird when I can’t sleep in the summer.
Love the sound of the sea. Can hear it every day. I’m very lucky 
also love sound of the rain. And birds
Least favourite sound - motorbikes and thunder. If i hear thunder (fortunately rarely in Cape Town) my heart starts racing and I go into panic mode.
