U of Pittsburgh Researcher Working on Tinnitus Drug
The drug they’ve been focusing on, called RL-81, would be used soon after tinnitus develops, and recent research indicates it could remain effective much longer than they first expected.

Vanderbilt Researchers Receive $3.1M Grant for Customizable Cochlear Implant Programming
These models will ultimately enable development of next-generation programming strategies that rely on these computational simulations of implant performance to find programming settings that greatly improve sound quality for cochlear implant users compared to the traditional programming approach.
Study: Mosquitoes Can Hear Up to 10 Meters Away
Cornell and Binghamton University researchers found, reportedly for the first time, that mosquitoes can hear over distances much greater than anyone suspected.

University of Sydney and Cochlear Limited Study Speech Comprehension in Cochlear Implant Recipients
In the study, recently published in “Ear and Hearing,” experts have found a correlation between a computer model and the speech intelligibility in implant recipients. This might mean that by improving the performance of the model, the performance of individuals with cochlear implants may benefit in ways that have never before been explored.

Cochlear Implants: Considerations Regarding the Relationship between Cognitive Load Management and Outcome
This article examines listening effort, auditory working memory, speech-in-noise comprehension, and the large network of interconnected brain areas now known as the “listening connectome.” Written by Edward Overstreet, PhD, and Michel Hoen, PhD, they explain why traditional speech perception measures in quiet may be insufficient for evaluating the effectiveness of many of the latest advances in CI technology.

Cortical Neuroplasticity in Hearing Loss: Why It Matters in Clinical Decision-Making for Children and Adults
With a better understanding of cortical brain changes associated with hearing loss, the potential to develop objective brain-based tools (ie, biomarkers) increases. These tools may help clinicians determine when a patient should receive intervention, what kind of intervention or rehabilitation would be ideal, and may offer the ability to monitor how well a chosen intervention or rehabilitation method is working. Prominent researchers Anu Sharma and Hannah Glick explain why.

Research: ‘Context’ Matters When Brain Interprets Sounds
The brain’s interpretation of sound is influenced by visual cues and other senses to determine what we hear, according to research at NYU Langone Medical Center, where researchers found that hearing nerve cells rely on context to help interpret sounds.

How Noise Exposure Alters the Brain
Researchers have found that, in mice, prolonged noise exposure altered cells connected to the brain, and it’s likely that synapses become enlarged in noise exposure to create space for chemicals that deliver messages to the brain.

Cochlear Implant Used in Gene Therapy to Regrow Auditory Nerves
Researchers have for the first time developed a way of using electrical pulses delivered from a cochlear implant to generate neurotrophins which can help regenerate auditory nerve endings. Ultimately, the therapy could allow CI users to enjoy a broader dynamic and tonal range, and it also has implications for other devices used in deep brain stimulation.
