An anonymous reader writes "Depending on the level of hearing impairment, conventional aids may not be good enough and a hearing implant is the only option. Until now the required surgery to fit them has taken several hours. However, that is about to change. A new implant that can be fitted with outpatient surgery has been developed consisting of a 1.2mm electro-acoustic transducer, which is positioned at the so-called 'round window,' which is where the middle and inner ear connect. It then produces amplified mechanical vibrations that stimulate the auditory nerve. Even though the transducer is tiny, it can reach volumes of up to 120 decibels."
