Shelly Horton on why proactive hearing health is an act of love

For journalist and TV presenter Shelly Horton, looking back at video clips from her milestone 50th birthday brings a flood of pure joy. Held on a boat slicing through the sun-drenched waters of the Gold Coast, the event was affectionately dubbed the “Shellebration”. The soundtrack to that day was a beautiful, chaotic symphony: the thrum of the boat engine, the splash of the wake, music playing, champagne flutes clinking and a crowded deck of her absolute favourite people all talking over one another.

“I just love those sounds,” Shelly says, her face lighting up as she watches the footage. “They take me straight back.” But amid all that joyful noise, the emotional anchor of the entire celebration was a touching, brilliant speech delivered by her father. It’s the kind of milestone memory we all strive to hold onto — yet Shelly points out that our capacity to truly live in these moments relies entirely on an invisible cognitive superpower we frequently take for granted: the “cocktail-party effect”.

As Specsavers senior audiologist Melissa Chandler explains, “The cocktail-party effect is our brain’s remarkable ability to isolate a single voice in a crowded environment while tuning out background distractions. A healthy auditory system acts like a sharp social lens, letting you focus on your conversational partner while reducing the interference of the surrounding ambient noise.”

But when our hearing begins to shift, that vital filter loses its clarity. Crucially, as Shelly has noticed, this change doesn’t mean the world suddenly goes quiet. Instead, it gets overwhelming. “What I find so interesting about hearing loss is it’s not actually about the world being too quiet,” she notes. “It’s actually about being too busy. It’s where you can’t filter out the clatter of the plates or the music from the person sitting right next to you.”

Chandler adds that when that inner cognitive filter degrades, navigating a busy social environment can turn into an exhausting mental workout. “The mental energy required to piece together words in a noisy room causes a very specific kind of fatigue,” she explains. “To cope, many people adopt subtle, subconscious behaviours — leaning in uncomfortably close to catch sentences or relying heavily on reading lips to fill in the blanks.”

Eventually, the sheer energy required to keep up becomes too taxing. Recent YouGov consumer research commissioned by Specsavers Audiology reveals the hidden scale of this social retreat.

Among Australians who struggle to catch conversations in noisy settings, a staggering 61 per cent resort to pas
