The sound of water flowing through rapids.

My grandma¹s house is built right next to a small river, this was the sound that put me to sleep every night.

Rain outside my window in the garden. Maybe not the MOST, but it’s up there.

Light rain on leaves

Crashing waves at the beach. Seagulls are little assholes but they add to the effect for me

The sound of rain on a tent mixed with a crackling fire, very relaxing.

My cat purring.

creaky wooden ship on stormy seas or rainy day steam train noises are so nice for me

The gentle thrum of a Federation starship’s warp core.

Wind blowing though pine trees.

I have this memory from when I was a kid. I was standing in the middle of the woods at my grandparents, watching big fluffy snow flakes fall around me. The only sound I could hear was a light breeze blowing through the pine trees. I don’t know why but it almost felt magical. To this day I still love that sound.

Cat’s purr

I can’t decide, there are too many:

Mongolian throat singing with little to no instruments.

The sound of a plane cabin (I think its brown or pink noise)

The fire crackling of a fire place or furnace.

Ocean waves or waterfall or river noise.

Slowly and softly played piano.

A stew slowly cooking.

Sound of gentle brushing your head hair.

Locally, indoors? Silence.

I like to be able to hear whatever is going on outside. Ideally, that would also be silence, but if something is going on outside, I like to be alert and aware of it.

I’ll also take a little rain and occasional thunder outside, as usually people aren’t acting a fool outside during rainy weather.

Train whistle in the distance. Light rain and thunder.

A babbling brook.
