A low hum in Pongakawa, Bay of Plenty
Low frequency hum - like twin diesel engines occasionally resonating louder. I used to live near the beach south of Auckland. I believed it was a local generator. Then I thought it was a distant ship with twin engines doing some sort of a dredging operation. Then I heard it 100 kms away in the mountains! I�m convinced it is a long distance wave form. Wooden houses behave like a bass speaker box. I wonder if the evenings are worse because the lower ionosphere reflecting the (radio?) waves back down to earth, thereby reaching a large geographical spread.
Changes with weather: I�m aware that there are air mixing propellers in the surrounding kiwi fruit orchards, I�ve heard them, I�m very sensitive to them. However they are powered during winter nights when a frost is expected, it�s been summer for the last 6 months, yet I hear the hum. They also free-wheel in the wind, but there often is nil wind, and I hear the hum. I recall once the hum stopped suddenly.

Write it down while you still remember the details. We will look for the others.
If this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
