Protect & Improve Your Hearing & Brain Health | Dr. Konstantina Stankovic

What It Covers

Dr. Konstantina Stankovic explains how hearing loss affects 1.5 billion people globally, its direct link to dementia and cognitive decline, practical protection strategies including magnesium supplementation and safe noise exposure limits, tinnitus mechanisms and treatments, and emerging regenerative therapies for restoring auditory function.

Key Questions Answered

• •Noise exposure limits: Safe listening is 80 decibels for eight hours, halving time for every three decibel increase. Concerts at 110-120 decibels require 30-decibel attenuation earplugs. If others hear your headphones, volume is too loud. Two noise traumas close together cause synergistic damage worse than either alone, similar to concussion vulnerability.
• •Magnesium protection: Studies in military personnel show magnesium supplementation before noise exposure reduces hearing loss. Magnesium threonate crosses the blood-brain barrier most effectively. Population studies link higher magnesium serum levels with better hearing preservation. Take magnesium before concerts or loud events as preventive measure against cochlear damage from artillery or amplified music.
• •Hidden hearing loss: Standard audiograms miss 90% of auditory nerve damage. People can lose most cochlear synapses connecting hair cells to neurons while maintaining normal hearing test results. This causes difficulty understanding speech in noisy environments and tinnitus. New tests measuring speech-in-noise comprehension identify at-risk individuals before traditional hearing loss appears on standard testing.
• •Hearing-dementia connection: Hearing loss directly correlates with cognitive decline and dementia risk, costing nearly one trillion dollars annually in lost productivity and healthcare. Cochlear implants improve tinnitus in 75% of recipients, with 10% experiencing complete resolution. Restoring peripheral hearing function allows brain recalibration, suggesting early intervention prevents downstream cognitive deterioration and social isolation.
• •Fetal hearing development: The cochlea fully forms during second trimester, allowing fetuses to hear maternal voice in utero. This early auditory exposure tunes infant auditory cortex to specific voice frequencies. Children reach adult ear size around age 10. Younger individuals show greater vulnerability to noise damage than adults at identical sound intensities, requiring stricter protection.
