Children with active ear infections are at a higher risk of a painful condition called barotrauma, which is experienced when the middle ear attempts to equalize to the changes in pressure.
Irrespective of the technique that is used, the implantation of a bone-anchored hearing device or an active middle ear implant should be taken into consideration preoperatively in order to restore complete hearing in cases of congenital atresia.
It has been recently shown that mechanical stimulation of the round window membrane with an active middle ear prosthesis produces cochlear microphonics and stapes velocities that are functionally equivalent to acoustic stimulation [ 26].
"This gives us a lot more active ears and eyes," says Hmer. Knowles now spends a considerable part of his time coordinating company research programs, including those at U.S. bioengineering subsidiary Genentech (66% owned) and the group's Syntex research labs in California.

Volkow is an innovative brain researcher who is director of the National Institute on Drug Abuse in Bethesda, Md. She recruited 47 people and placed an "active" phone next to one ear (the phone was on — generating radiation, but silent, so that Volkow could eliminate the effects of sound and conversation).
Increasing evidence demonstrate that the inner ear is an active immune organ rather than an 'immunologically privileged organ' that was generally accepted previously [36].
Each dairy cow was equipped with an active tag applied to one ear and a reference tag was fixed to a pillar of the barn.
Spontaneous otoacoustic emissions are one manifestation of an active process that improves the ear's performance in three ways [reviewed in [4] [6]].
These results show for the first time that autophagy is an active process during early inner ear development that provides the energy required for the clearing of dead neuroepithelial cells and for the generation of neuronal otic precursors.
