Perfect pitch

Allen has Perfect Pitch.
Well, he calls it Absolute Pitch.
Musicians and experts tend to call it that instead of the pedestrian term Perfect Pitch.
He can hear a sound and tell you what note on the scale it is.
That coffee mug is a B flat.
That siren is a C sharp.
That woman is screaming in a high A.
And that explosion is… well… after the bright flash and shock wave and the wall of flame, Allen can’t tell us what its note was.
I think the Geiger Counter clicks a D.
But I don’t have Perfect Pitch.
