AARP Article Cites Reasons to Treat Hearing Loss
The article mentions the brain changes that studies have shown may happen when hearing loss remains untreated, potentially causing visual and sensory processing centers to access the auditory cortex, which can result in deterioration of the cortex over time.

White Noise May Improve Auditory Perception
The data of the research group showed that white noise significantly inhibited the activity of the nerve cells in the auditory cortex. Paradoxically, this suppression of the neuronal excitation led to a more precise perception of the pure tones.

Researchers Identify Brain Regions in Blind Individuals Responsible for Sharpened Auditory Function
Research has shown that people who are born blind or become blind early in life often have a more nuanced sense of hearing, especially when it comes to musical abilities and tracking moving objects in space (imagine crossing a busy road using sound alone). For decades scientists have wondered what changes in the brain might underlie these enhanced auditory abilities.

CILcare Initiates Second Phase of Tinnitus Research Project DETECT
In Phase 1, CILcare was reportedly able to correlate electrophysiology, manganese-enhanced magnetic resonance imaging (MEMRI), and behavioral assessments that define a preclinical model for detecting tinnitus. In Phase 2, CILcare will adapt the preclinical model to humans.

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.

Visual Cues May Help Amplify Sound, University College London Researchers Find
Looking at someone’s lips is good for listening in noisy environments because it helps our brains amplify the sounds we’re hearing in time with what we’re seeing, finds a new University College London (UCL)-led study.

Auditory Cortex is Nearly Identical in Deaf and Hearing People, Study Finds
Harvard University researchers and colleagues have found that the neural architecture in the auditory cortex—the part of the brain that processes sound—is virtually identical in deaf and hearing people. The study raises new questions about the role of experience in processing sensory information.
