Commercially Available Low Cost Hearing Aids and these Limitations

  • Masafumi Nakagawa

Abstract

The incidence for the congenital profound sensori-neural deafness in birth will be one to two out of 500 cases or 0.2% to 0.4%. Now we can screen out the newborn deaf baby with accuracy using the mass screening system with the automated ABR (Auditory Brainstem Response) and/or the OAE (Oto Acoustic Emission). Some of them will be able to improve their hearing acuity with surgical technology of the cochlea implants. However, this story is only affordable in the developed countries.
