A low hum in Unites States of America, Mckinleyville

An extremely low frequency sound that I can barely hear but at the same time is extremely loud, especially in my bathroom and my bedroom. Seems to not exist outside or for other people. When sound is at its worst i swear it is similar to a helicopter hovering overhead. No, Im glad that I finally found a person or group who hears the same things that I do and that I may not be crazy afterall.
