3D Printing Improves Cochlear Implants for Users

A team of engineers and clinicians have used 3D printing to create intricate replicas of human cochleae and combined it with machine learning to advance clinical predictions of ‘current spread’ inside the ear for cochlear implant (CI) patients. ‘Current spread’ or electrical stimulus spread, as it is also known, affects CI performance and leads to 'blurred' hearing for users, but no adequate testing models have existed for replicating the problem in human cochleae – until now.

Male Mosquitoes’ ‘Phantom Tone’ Helps Amplify Sound of Female

The mixing of the two sounds, of the female wingbeat and the male’s own wingbeat, generates an additional distortion tone, or ‘auditory illusion’ that’s only present in the antennae (or in the ears of mammals). The flagella’s spontaneous vibrations change to be the exact same frequency as the female wingbeat, to maximally amplify the illusion.

Researchers Identify Brain Factors Linked to Success of Cochlear Implants

Using data from brain imaging techniques that enable visualizing the brain’s activity, a neuroscientist at the University of Geneva (UNIGE) and a Parisian ENT surgeon have managed to decipher brain reorganization processes at work when people start to lose their hearing, and thus predict the success or failure of a cochlear implant among people who have become profoundly deaf in their adult life. The results of this research may be found in Nature Communications.
