Why do whispers, soft tapping, and rustling pages trigger warm, tingling waves in some people but leave others completely unaffected? In this episode of Earvangelism, we explore the deeply personal and surprisingly emotional world of ASMR.
We break down what ASMR is, how the auditory system processes these intimate sounds, and why the brain sometimes interprets them as calming, safe, and pleasantly immersive. Along the way, we look at attention, memory, binaural recording, and how ASMR sits at the intersection of sound, emotion, and human connection.
This episode is an invitation to understand how sound shapes not just what we hear, but what we feel.

Why does the world sometimes feel like it has no middle volume? This episode of Earvangelism unravels the science of auditory recruitment, where damaged hair cells in the ear distort how we experience sound.
We’ll talk about how this phenomenon blurs the line between silence and noise, how it affects communication and comfort, and why understanding it reveals so much about the delicate relationship between the ear, the brain, and perception itself.

They both make things louder, so what’s the big deal? Quite a lot, actually. In this episode, we look at the growing world of over-the-counter hearing amplifiers — how they compare to prescription hearing aids, when they might help, and when they might do more harm than good.
From custom fitting to feedback control and brain adaptation, we’ll dive into the science of why “louder” doesn’t always mean “clearer.” If you’ve ever wondered whether those online amplifiers are worth it, this one’s for you.

Have you ever cringed at the sound of your own voice on a recording? You’re not alone — and there’s real science behind that discomfort. In this episode of Earvangelism, we explore why your voice sounds so different when played back, and what it reveals about how your hearing actually works.

From the physics of bone conduction to the quirks of recording technology, we’ll unpack how microphones, skull vibrations, and brain expectations all shape the voice you think you have. And we’ll ask a deeper question: why does hearing ourselves from the outside feel so strangely personal?

What if you could hear your eyes move? Or your own heartbeat echoing in your skull?
In this episode of Earvangelism, we explore Superior Canal Dehiscence Syndrome (SCDS) — a rare and fascinating condition where a tiny hole in the inner ear blurs the line between sound, balance, and self-perception.
We’ll unpack the anatomy, the surreal symptoms, the challenges of diagnosis, and how surgical repair can help patients reclaim their sense of silence.
Join us as we dive into the “third window” of the inner ear — and discover what happens when hearing turns inward.

In a world full of sound, our brains are expert editors — deciding what’s worth hearing and what’s not. This episode of Earvangelism dives into the phenomenon of selective hearing: the fascinating intersection between perception and attention.

We’ll explore the neuroscience behind why some sounds capture our attention while others fade into the background. From survival instincts to modern distractions, and from romantic frustration to neural efficiency, selective hearing reveals how finely tuned — and biased — our auditory systems really are. By the end, you might rethink what it truly means to “listen.”

What if everyday sounds like chewing, tapping, or breathing made your skin crawl or sent your stress levels through the roof? In this episode of Earvangelism, we dive into misophonia — a condition where ordinary sounds trigger intense emotional and physical reactions. We’ll explore what science knows so far, why it happens, and how people cope with it. Whether you’re an audiologist, a healthcare professional, or someone who struggles with sound triggers, this episode will help you understand misophonia’s impact on the brain, behaviour, and daily life.

In this episode of the Earvangelism Podcast, we unpack the key factors that determine how effective hearing aids truly are. From the degree and type of hearing loss, to the role of technology, fitting formulae, and audiologist expertise, through to the brain’s remarkable ability to adapt — we explore why success with hearing aids depends on much more than the device itself.

You’ll hear why consistency is critical, how patient feedback shapes customization, and why encouraging friends or loved ones to give their hearing aids a real try can make all the difference. Finally, we step back to remind ourselves of an important truth: no matter how advanced the technology becomes, nothing compares to the natural hearing we’re born with — which makes protecting our ears more important than ever.

In this episode of the Earvangelism Podcast, we dive deep into the world of hearing aids . We’ll explore what hearing aids actually are, the key components that make them work, and how modern programs adapt to different listening environments. You’ll also learn about the different styles available — from discreet in-the-canal devices to behind-the-ear models — and the differences between tubes and wires.

Whether you’re curious about how these tiny technologies restore clarity, considering hearing aids for yourself or a loved one, or simply want to understand how they enhance everyday life, this episode will give you clear insight into one of the most important tools for better hearing.

They promise peace and quiet at the push of a button — but what’s really going on inside your noise-cancelling headphones? In this episode of Earvangelism, we break down how these devices actually work, why they feel so effective in loud environments, and the surprising ways they can both help and harm your ears. Are they the ultimate tool for focus and calm, or could constant use come at a cost? Tune in to find out what the science says — and how to use them wisely.
