The reason why road crews the world over test microphones by saying One … two … one … two is not, as popularly imagined, that road crew can't count.

The practical reason is this - when the voice says One into the microphone, the Wah sound of One gives the sound engineer at the desk a reading for the bass response on the microphone.

The when the voice says Two ino the microphone, the Tah sound of Two gives the engineer the treble response on the microphone.

Repeating the phrase allows the engineer to balance the higher and lower pitches of the microphone sound.

So next time you hear a roadie endlessly intoning One ... two ... one ... two, sometimes followed by a raised voice Yah and Hey for the volume readings, you'll know why.
