Low pulsing hum like that of an idling engine or generator on the edge of perception. It seems to vibrate the ear drum at the tip of each pulse almost like the ear drum is spasming. I have a casual job which I ride to and as I ride home late at night I can hear it very clearly in the distance along the footpath, like a rumbling of thunder or a motorbike speeding, but as I go into the trees and the wooded area around my house it vanishes and is only audible as the humming sound indoors. As well as this, it is much more audible near walls than in the middle of rooms.
