It depends on where you are raised.

I need to make deals in cities like New York, or London or Paris, Frankfurt, or Madrid.

At buildings, specially hotels in those cities there is a constant hum, low level noise all the time that is specially present when you need to sleep.

People that are raised in cities are hearing this sound all the time. I was raised outside them so for me this sound is alien but for those people it means "home".

It was incredible being in Paris or Madrid center with COVID and hearing birds as background instead of road sounds.

I need birds or sea waves or tree leaves sounds in order to work and focus. Cars or air blowers sounds are really distracting for me.
