Optacon users are busy responding to the buzz. We feel it as well as hear it and I don't think it bothers us for that reason. If it were a steady buzz, a sound that continued at the same pitch and level all the time, I think most people could tune it out. As it is, the intermitent nature of the buzz would be annoying to some people. Others would have a legitimate auditory problem with it. I know that because I could never sit anywhere near a photocopy machine. The hum of the thing did something inside my head. I could operate a copy machine and it did not bother me, but I couldn't sit next to one for any extended period. I summary, some people who are not directly using the Optacon might find the buxx unsettling because of something in their auditory mechanisms.
