Changes in endolymphatic potential and crossed olivocochlear bundle stimulation alter cochlear mechanics.
Mechanical nonlinearity in the cochlea produces acuoustic distortion products that can be measured in the ear canal. These distortion products can be altered by changes in the endolymphatic potential as well as by stimulation of the crossed olivocochlear bundle, which provides efferent innervation to cochlear hair cells.
