Podcast Summary: What's That Rash?

Episode: "Could headphones be damaging our ears?"

Date: March 10, 2026
Host: ABC News
Hosts: Norman Swan, Fiona Pepper

Brief Overview

In this engaging, question-driven episode, Norman Swan and Fiona Pepper explore the increasingly relevant question: are headphones damaging our ears? Prompted by several listener emails, they dive into the science of hearing, the history of headphones, how modern habits might be increasing our risk of hearing loss, and what we all can do to protect our ears—without giving up our favourite music or podcasts.

Key Discussion Points & Insights

1. Listener Questions: The Health Impact of Headphones

Timestamps: [01:45–02:32]

Mel: Asks if attending loud music events or using in-ear headphones leads to long-term hearing damage.
Alida: Wonders if the prevalence of earbuds is affecting hearing ability.
Katie: Is curious about the impacts of headphone use on hearing, ear health, cognition, and connection to the world.

Memorable Quote:

"I'm really excited to get into this one."
— Fiona Pepper [02:31]

2. Assessing Personal Risk: Noise Exposure Calculators

Timestamps: [02:32–03:43]

Fiona and Norman discuss their results from an online noise risk calculator, prompting reflections on subtle but cumulative exposures—like blasting show tunes in the car.
They clarify it’s not just single loud events, but chronic, frequent exposure that damages hearing long-term.

Memorable Quote:

"Turns out it is about chronic, long-term and frequent exposure to loud noise that really does do the damage."
— Norman Swan [03:22]

3. A Brief & Fascinating History of Headphones

Timestamps: [03:51–09:44]

Original in-ear headphones were patented in the 1890s for telephone users.
More mainstream access came from Britain’s Electrophone service (theater/opera by subscription) and the military’s telegraphy needs.
Evolution through stereo headphones (20th century), Walkman revolution (late 1970s), and early moral panics about youth and hearing loss.

Memorable Quotes:

"He patented a set of in ear headphones that are not actually that different to... what we would have these days."
— Fiona Pepper [04:43]

“When new technology comes along, it’s always doom and destruction, and then maybe it’s partial destruction, but not total doom.”
— Norman Swan [09:44]

4. The Science: How Hearing and Hearing Loss Work

Timestamps: [09:51–12:38]

They break down how sound reaches the brain: eardrum → middle ear bones → inner ear (tiny hair cells in fluid)—damage to those hair cells = hearing loss.
Bone conduction headphones and tests are discussed, with caveats: bone conduction bypasses the middle ear but can still damage the inner ear at high volumes.

Memorable Quote:

“These little hairs in your inner ear are very sensitive and they're the ones that get damaged with loud noise.”
— Norman Swan [11:29]

5. Prevalence and Population Risk

Timestamps: [12:46–13:45]

Workplaces like aviation and factories need hearing protection due to occupational risks.
The World Health Organization estimates over a billion young people are at risk for early hearing loss due to unsafe headphone/audio device use.

6. Hearing Loss: Social & Cognitive Consequences

Timestamps: [13:45–15:37]

Hearing loss possibly linked to cognitive decline and social isolation, though the relationship is complex and not fully understood.
Headphones may reduce day-to-day social connection, but can be beneficial for neurodivergent individuals (e.g., those with autism).
Noise-cancelling headphones are probably a better choice for hearing health—they allow users to listen at lower, safer volumes.

Memorable Quotes:

“Noise cancelling headphones are probably better for your hearing than non-noise cancelling. That’s because the noise cancellation allows you to turn down the volume.”
— Norman Swan [15:01]

7. Safe Listening Habits: Myths, Guidelines & Practical Tips

Timestamps: [16:44–18:07]

No strong evidence that noise-cancelling headphones cause "auditory processing disorder".
General advice: use the lowest comfortable volume, protect your ears at concerts/clubs/work, and take regular breaks.
The “80-90 rule”: Listen at no more than 80% volume for no more than 90 minutes per day.
Occupational exposures are still a major risk.
Earplugs are recommended for regular exposure to loud environments.

Memorable Quotes:

“Find the lowest level that you can achieve that you can hear it comfortably.”
— Norman Swan [17:11]

“Noise cancelling is a really good idea...But just keep that volume down.”
— Norman Swan [19:26]

8. Broadening the Picture: Brian Johnson & Hearing Aids

Timestamps: [18:07–19:18]

Celebrity "biohacker" Brian Johnson wears hearing aids due to, in his words, gunshot and music exposure in childhood—a reminder that hearing damage can’t be reversed; hearing aids are the only effective solution once hair cells are lost.

9. Practical, Personalized Takeaways

Timestamps: [19:18–19:47]

Bottom line:
- Keep volume as low as possible
- Noise-cancelling vs. in-ear/over-ear: use what’s comfortable, but volume is key
- Protect your ears in loud environments

Notable Quotes & Memorable Moments

“Sometimes, that’s the point—sometimes if you’re on a bus and you’re like, please don’t talk to me, I’m going to put on these big can headphones as a signal to leave me alone, please.”
— Fiona Pepper [14:52]
“It’s the volume that counts.”
— Norman Swan [15:37]

Conclusion

If you’re worried about headphone use and your hearing:

Keep the volume as low as possible.
Noise-cancelling headphones help you avoid turning up the volume in noisy environments.
Both in-ear and over-ear headphones can cause harm at high volumes; comfort and listening habits matter more.
Hearing loss is common, can be socially and cognitively isolating, and is essentially irreversible.
Take breaks, use hearing protection where needed, and remember: “It’s the volume that counts.”
