Back voice

Sound perspective of a person heard as if speaking with his back facing the listener. This effect is related to the direct sound recording technique and incorporates the sonic physical qualities resulting from such a situation. The high frequency content of the signal is being altered by the microphone placement. In that situation, the listener translates the signal by understanding the emitter positioning sonically.


  • Spatial coordinates are embedded into the sound from its point of recording
  • The loss of high frequencies can potentially result in a loss of intelligibility

Complementary effect: Sound distance
Opposite effect: Frontal voice

(Chion, 1994)
