Is this something I should be concerned about?

The MBTA has been installing these things at all of the above ground stations that give off a sound that only birds can hear to get rid of pigeons on the platforms. I first came across them a few months ago at the Beachmont station on the blue line. Here's the thing: I can hear them... and it hurts. Jessica thought I was crazy, but it started before I even knew they were there. I just hear a high pitched noise and feel a bunch of pressure in the back of my head. Now they are putting them all over the place. I really don't like the implication: that i must be somehow pigeon like, but I don't see an alternative explanation.
