Age-Related Central Auditory Processing Disorder (CAPD): Could It Be Causing Your Hearing Issues?
Central Auditory Processing Disorder (CAPD), also known as APD, is a condition where the brain struggles to process and understand sounds despite the ears functioning well. While commonly associated with children, CAPD can also affect adults, particularly older individuals, as their auditory system ages. Common symptoms include difficulty understanding speech in noisy environments, trouble following complex instructions, and challenges in reverberant settings. Diagnosis is often delayed because s...

Protecting Your Child's Hearing
Hearing loss, traditionally associated with older adults, is increasingly affecting children and teenagers due to prolonged exposure to loud noises, particularly from personal audio devices like headphones and earbuds. With statistics showing that one in five U.S. teenagers and 15% of children aged 6–19 have some form of hearing loss, noise-induced hearing loss has become a significant concern. To mitigate this risk, it is crucial to educate children about safe listening practices, such as keep...

Aging Actively
Active aging focuses on enhancing healthy life expectancy and quality of life, with hearing playing a crucial role in maintaining overall well-being. Hearing loss, now the fourth leading cause of years lived with disability, significantly impacts physical and mental health, cognitive function, social interaction, and independence in older adults. Emerging evidence suggests that untreated hearing loss may contribute to cognitive decline and even early signs of dementia, while interventions like he...

Face Masks and Hearing Aids
The COVID-19 pandemic has significantly impacted hearing healthcare, particularly for individuals with hearing impairments. Wearing masks to prevent the spread of COVID-19 creates two main challenges: visual and acoustic barriers. Visually, masks block lip-reading, which is crucial for many hearing-impaired individuals, though clear masks have partially addressed this issue by allowing mouth visibility. However, research shows that clear masks may also negatively affect high-frequency sounds like...

October is for Football – and protecting your hearing!
October is National Protect Your Hearing Month, highlighting the importance of safeguarding against noise-induced hearing loss (NIHL), which affects millions of Americans. The article explores how common sounds, including stadium noise at NFL games, can be damaging. For instance, Arrowhead Stadium holds the record for the loudest NFL crowd at 142.2 decibels, surpassing the sound of a jet engine and classified as "painful and dangerous." Even with limited attendance during the pandemic, NFL teams ...

The Problem with Frequency Compression and Music
Modern hearing aids include a feature called "frequency compression," which lowers the pitch of high-frequency harmonics. While this can be beneficial for speech, it often causes dissonance and distortion in music due to its reliance on precise harmonic frequencies. The article explains that altering these harmonics, even slightly, disrupts musicality, particularly when dealing with instruments like flutes or violins, which share identical harmonics at exact frequencies. Three audio examples demo...
