When the basilar membrane vibrates up and down in response to the sound wave, the hair cell cilia are displaced 1. st. in one direction then in the other; i.e., 1. Many factors can affect transduction efficiency. Not all viral particles floating in culture medium can eventually transduce (or infect) the cells.
