Episode 5: The Hidden Connection: Hearing, Brain Health & How You Age
Most hearing tests only tell you part of the story. In Episode 6, audiologist Craig Lett explains how hearing loss affects your brain, sleep, balance, memory, and cognitive health — and how Ear360, the world's most comprehensive hearing assessment, is changing the way we approach hearing care.

A quick hearing check tests your ability to hear sound. But it doesn’t explain how your hearing affects your sleep, memory, balance, tinnitus and brain health.
In Episode 5 of Resonate the Podcast, Lesleigh Smith sits down with Craig Lett to discuss how there is more to hearing than most of us realise.
Craig is a senior audiologist at Resonate Health and PhD candidate at the University of Auckland. He was instrumental in developing Ear360, the world’s most comprehensive hearing assessment. Ear360 goes far beyond testing hearing ability, exploring the connection between hearing and other areas of your life, such as balance, sleep, tinnitus, memory, and cognitive fitness. In this conversation, he and Lesleigh unpack:
The science behind Ear360
- How hearing loss affects the brain, cognition, and mental workload
- The links between hearing, balance and sleep
- The invisible consequences of untreated hearing loss
- Why Resonate Health developed Ear360
- How much more there is to hearing than most of us realise
- How a whole-of-person approach to hearing care could change how we age.
