Click For Summary
Noise levels in high-rise buildings, particularly above the 80th floor in urban centers like New York or Seoul, can be significant due to constant traffic sounds, including car horns and sirens. Residents may find it challenging to tolerate this noise, especially when considering the volume of sounds from below, which can be comparable to hearing an airplane at high altitudes. The World Health Organization recommends a maximum noise level of 40 dB outside bedroom windows at night, indicating concerns about urban noise pollution. Despite the height, the sound from the city can still penetrate high-rise apartments, affecting residents' comfort. Ultimately, individual tolerance to such noise levels varies, and living in a skyscraper with open windows may not be ideal for everyone.

What is the noise level at a high rise building if one was supposed to leave the window open in a balcony on the 80-th floor and above in an apartment on a skyscraper built in the city center of a large city like New York or Seoul, with all this car traffic underneath with their horns and sirens blowing full blast all day?

I mean, I can hear the engine of a small airplane in the sky when it's flying 1000 meters above me very loud, so I guess it must be the same when I am above ground at 500 m and the traffic is below me.

I must conclude that I could not tolerate so much noise. Am I right?

You live in a skyscraper where you can open a window? Where?

Oh, I guess there will be many apartments on the 75th floor and above in Miami or Hong Kong say, complete with balconies to lounge outside.

I wish I were living in one but no! I am just asking what's the situation with all this traffic and city noise below your feet.
 
I am following someone on Youtube who has built a rocket shaped (4 proprllers) drone for the world speed record ... He was having problems with internal heat from electical control gear and battery inside the sealed rocket (about 1kw waste heat) Speed is 500km/hr , I suggested a 4mm hole in the tip of the nose and 8mm hole at rear which should alow sufficient air cooling .. I said this will increase thrust because the air exiting is hotter .. a bit similar to a ram jet ... was I correct...
Quick question that I haven't been able to find the answer to. Greenhouse gasses both warm and cool the atmosphere by slowing heat loss to space. But what would happen without GHGs? I read that the earth would be colder (though still relatively warm), but why? Without GHGs the atmosphere would still be a similar mass and still warmed by conduction from the surface, yet without a means to radiate that heat to space. Why wouldn't the atmosphere accumulate heat over time, becoming warmer? How...
