low vibrating hum sound with almost a rhythm to it that quickens at times, from 3 longer sounds with a pause to more rapid sounds. Sounds like a distant motorcycle or helicopter idling or a very low subwoofer, but it's like I feel it to my core. It isn't constant every day, but it happens frequently and right now I am hearing it very strongly. It almost makes me feel sick...like motion sick. It's hard to concentrate and it's making my head hurt. find a way to make it stop please. it's making me feel crazy
