A low, vibrating sound that rarely stops. Often it has a pulsing quality. Sometimes it sounds bearably distant, at others unbearably close. Classic descriptions of a car or truck idling or a distant aircraft faintly shaking the windows are accurate. More noticeable at night and indoors, but present outdoors and during the day as well.
