Earlier quoted context omitted.
One thing I've noticed is that people in the UK are way more considerate about and sensitive to noise whereas the opposite is true to Asians. Go to China and the level of ambient noise is much higher, whether that is people talking louder or having no qualms playing music from their phone speakers at any time of the day. So at a guess, I think that cultural conditions probably lend themselves to people of Asian herit…
I cannot comment about Asian culture but conditioning does have a large part to play in how people sleep. Personal anecdote: when I grew up my parents lived on a busy main road so I was used to sleeping in noisy conditions. I then moved to a quiet village - I love how silent it is on a night - but I now cannot sleep in hotels nor anywhere else unless it's absolutely silent.
They say in the army, your survival is predicated on being able to catch a wink wherever possible.
As for sleeping in quiet places, one thing I've noticed is that my tinnitus is only audible when I am not in a city, as such there have been times where I remember I have tinnitus and am temporarily unable to sleep because of it.
