Last week, several West Seattle residents reported being bothered by a loud droning low-frequency hum that could be heard at night. One resident even managed to catch some great audio of the sound, which you can here archived here on the West Seattle Blog. Her recording starts with some typical street noises, but the hum kicks in around :30.
This hum has been heard off and on throughout the years. I remember hearing it when I lived on Alki, it was something that echoed through the air in the wee hours of the late summer nights, when the city was sleeping. I worked night shift, so I was awake when most people were not. I always wrote it off to the multitude of light and heavy industry sites within a few miles, from cargo containers being loaded at the shipyards, to the steel mill right beside the West Seattle bridge.
But this time, residents complained, and all the businesses in the area claimed it wasn't them. So what, then, could be the cause?
Some people think they have found the answer. But frankly, I have my doubts. Just because you see something on the evening news, that doesn't make it true! Even Jim Forman seems skeptical about this one.
