Got a p.m. and need to explain more clear ...
An independent study on which one is better Oticon v.s. Phonak BTE hearing aids, other BTE hearing aids can be included in the independent study.
then a separate study with cochlear implants. Cochlear Americas v.s. Adanced Bionics and other cochlear implants one more ? There are three cochlear implant companies ? Which one is clearly the best CI in an independent study.
Not BTE hearing aids v.s. cochlear implants.
Thank you.
