Low throbbing I am able to hear many things others cannot, such as the humming of electronics (lights, CRT monitors/TV's, etc.), music being played far away, road construction several miles away, etc. However, I struggle to hear some sounds others can hear, such as human whispers. This recent throbbing/pulsating sound does not match anything from my prior experience, though is most closely related to large equipment sounds. As this sound continues through day, night, weekends, and a recent heavy snow storm, I'm not able to determine any correlation with construction projects in the area. If there's additional information I can provide, I can be reached at markais@gmail.com

the accounts read alike, found by meaning rather than by shared details
Write it down while you still remember the details. We will look for the others.
