jet engines are far louder, particularly at take-off (max thrust).

el trains clock in at about 90 decibels along the brown line, if they are at speed. comparable to standing close to a gas lawn mower.

some of the screeching around curves can get pretty irritating in a "nails on a chalk board" kinda way, but we live next to a straight run of track, so it's just that deeper rumble of a fast moving train on an elevated steel structure, no screeching.

commercial jet engines vary anywhere from 120 - 140 decibels at take-off. military jets, like the kind that might fly in and out of NAS oceania can be even louder if they have their afterburner on.


coincidentally, we also live directly underneath the approach path to one of ohare's runways, so we also get jets flying overhead all day long to compliment the el trains. but we're about 10 miles from the end of the runway, so the planes are still several thousand feet up in the sky and not quite so loud, though still very, very audible, especially those old MD-80s.

we also live close to swedish convenant hospital, so we get a lot of ambulance sirens as well.

ah, the symphony of the city. i find dead quiet places to be a little spooky. where's the noise?
