That’s not very common for a good reason given that airports create a lot of noise pollution.
Are airports louder than train stations? Near freight trains and air port and the freight trains are much worse for me personally. Though I would hope passenger train systems are designed for less noise.
Passenger trains are a lot less loud than planes taking off https://www.chem.purdue.edu/chemsafety/Training/PPETrain/dblevels.htm
