A low hum in Lutsen MN 55612

Sounds like a Diesel engine idling off in the distance, it is faint but constant and it will also fluctuate wooo...wooo... woooo.. My house is built on ledge rock overlooking Lake Superior. I�m wondering if the combination of the Great Lake and ledge rock acts as an amplifier. I can only hear the sound inside my home that is built into the ledge rock. If I go outside I can�t seem to hear or feel the sound as easily. I have turned off all the power to my home so I know it isn�t something mechanical in my house. I seem to be able to hear the hum better than my wife.

Low frequency hum, always same frequency, I'd estimate around 50hz (at least my perception). I only hear it at/in my home, if I'm at another location, I don't think I've ever heard of it.

Low, soft rumble - as if a large truck were idling in the distance - it varies, but not rhythmically - I can almost "feel" the vibrations. Most predominantly at night, in the bedroom on the

Low hum, sometimes pulsating, sometimes not. It is very loud. It sounds like a propeller airplane way off in the distance, but it doesn�t go away. Or an 18-wheeler on a busy freeway,

Dull Hum The hum sound has been present the entire time I've owned this particular home. It sounds like a truck idling in my driveway and disrupts my sleep. My bedroom is on top of granite

It is an extremely low vibrational hum that can be felt in my body. I just want to point out 1. It feels like it comes from he Earth. 2. My microphone can pick up the sound from my sound boo
