So, as always, I am listening to music, through my main system, and I......

freak out.......Behind my audio rack, I start hearing a sound, that is loud, frightening, and somewhat familiar...but have not heard it in a very long time. I have different components in my rack since last time I heard it. It is a sound, as if a component, is going into self destruction. Not through the speakers, which are to the left of my rack. I lower the music, and the noise stops. I play the music again, nothing, but music, and then...the noise is back. I lower the music, again, and I hear this buzzing coming from behind my amplifier, which is at the top of the rack. I start to reach behind my rack, and put my head near the amplifier, listen to this buzz, and then, the noise stops. I stand there in silence, and wait, until, the buzz comes back, which it does. Can't put my finger on which component this buzzing is coming from. After a brief moment of silence from my system and I, and a simple investigation, I calmly, discover the culprit. The wall behind my audio rack / system, is an exterior wall, and on the exterior side of the wall, back to back with my rack, is a Palm tree, home............ to a family of Cicadas. What a relief. I do not remember them, being this loud. In a month, they will be gone. Enjoy !, stay safe, and be well. Always, MrD.
