Pulsing light in Australia, Box Hill South
Pulsing, almost stuttering, single-frequency drone of estimated frequency 150 - 200 Hz. Only noticeable inside the house, at night, and more prominent when laying down. My spouse cannot hear it. I am guessing it’s a strange form of tinnitus. The sound pulses, almost stutters.
