End of game timing Q

[Camron Rust]

I once had a game where the a foul or violation was called (OOB?) just as tie was expiring for the quarter. It was so close to the horn that the horn had just started sounding but the stopping of the clock was so quickly after that you barely heard a blip from the horn. I was puzzled for a moment before realizing what happened. I don't remember the exact play, but time had expired and if we were not listening carefully or it had been noisy, we would have never heard the horn.
