Constructive Interference
Two voices, one diaphragm, no border.
Two waves that meet in phase
do not fight.
They add.
●
The microphone between them
is forty years old
and holds one opinion about
the world:
pressure.
A diaphragm twelve microns thick,
a coil, a magnet —
the whole apparatus of its judgment.
It cannot hear a border.
No one ever told it
there is one.
●
The note
they are both screaming
is an A.
Four hundred and forty hertz —
the pitch the planet agreed to call true in 1939,
the year it agreed on nothing else.
Two voices arriving at
the same frequency from
opposite sides of one diaphragm
do a thing physics names
without ceremony.
In phase,
they do not cancel.
They sum.
The film swings further
than either mouth could swing it
alone,
and what comes back
through the speakers
is not two people
being loud near each other.
It is one
waveform.
Louder than
the arithmetic of two.
This has never once made
an exception for whose lungs.
●
Their foreheads are
touching. Behind them
the city goes
the colour of a struck match.
Neither is winning.
●
A note
lasts four seconds.
It is longer than
the border,
which is a century old at most,
and which
the air has never agreed to
observe.
●
The microphone files it
the only way it can — as
amplitude.
It does not know
it just did the thing
the negotiators could not.
It only knows the reading ran high,
and held,
and that for the length
of one breath
it could not tell
two enemies apart.
●
Neither,
briefly,
could anyone.

The train arrives after midnight carrying soaked commuters and one screaming drunk philosopher. Somewhere at the edge of the observable universe, matter collapses into impossible density. Nobody looks up from their phones.
