He’s heard the expression
“the silence is deafening”
and he could never understand it.
Today they studied his eyes,
he staring into the the equipment,
lights changing and flashing,
they sitting, repeating “Blink.” 
Soon he understood what it was.
to be “blinded by the light”, and while
he waited for his eyes to undilate,
he imagined blindness, and
understood for the first time
in is life how a deaf person
might crave noise of any sort.
