  Gravitational waves are oscillations of space-time that are created, for
example, in black hole mergers. If these waves travel through another massive
astrophysical object, they will undergo an effect called gravitational lensing,
that will distort and deflect them. This effect can create multiple images of
the gravitational wave signal, and interference between them. In this document,
we describe the sonification process of the gravitational lensing effect on
gravitational waves. Sonification is the translation of data into sound. The
wave nature of sound creates interference between waves in a natural way. This
has allowed us to reproduce the interference produced by the superposition of
gravitational wave images, characteristic of the gravitational lensing effect.
