Believe it or not the only thing I listen to is the machine. Every once in awhile you detect that something isn't right. Bearing going, header not jiving right, etc.
I do however sing to myself....alot....spare you the footage!
My wife has this white-noise machine supposed to drown out me snoring, it plays raindrop sounds on metal roof, seashore, or crickets and rain frogs
I cant sleep with that shît on
After a while, on that crickets and frogs one, I can hear someone screaming at 6 second intervals. Its faint, really far off, but I can hear it.
