• The cochlea forms a key element of the human auditory system in the temporal bone. Damage to the cochlea continues to produce significant impairment for sensory reception of environmental stimuli. To improve this impairment, the optical cochlear implant forms a new research approach. A prerequisite for this method is to understand how light propagation, as well as scattering, reflection, and absorption, takes place within the cochlea. We offer a method to study the light distribution in the human cochlea through phantom materials which have the objective to mimic the optical behavior of bone and Monte‐Carlo simulations. The calculation of an angular distribution after scattering requires a phase function. Often approximate functions like Henyey–Greenstein, two‐term Henyey–Greenstein or Legendre polynomial decompositions are used as phase function. An alternative is to exactly calculate a Mie distribution for each scattering event. This method provides a better fit to the data measured in this work. We studied the light scattering by tissue phantoms in the context of optical cochlear implants. We present a phase function that can model the scattering pattern of those phantoms very well. These scattering angle distributions are supported by experimental investigations.
