I listened intently but heard nothing, “There’s no sound. You’re imagining it.”
He insisted but older ears don’t hear as well as the young. Faintly, I thought I heard the noise bothering him but where did the noise come from?
It was only after an intense search I realised the source of the sound. I turned the switch to off.
“It’s gone!” he yelled but I didn’t hear him.
At a frequency too high for my ears, I’d never noticed the high pitch tone coming from my hearing aid when the battery ran low.
