Hearing loss has emerged as one of the most significant modifiable risk factors for cognitive decline and dementia. Recent advances in hearing technology have opened new frontiers in understanding how auditory rehabilitation can influence brain plasticity and cognitive health.

The ECHHO Program (Enhancing Cognitive Health through Hearing Optimization) represents a pioneering initiative that integrates clinical evidence, user data, and innovative hearing aid technologies to explore the link between hearing aid use and cognitive outcomes. This program provides new insights into how personalized amplification strategies, real-life data collection, and machine learning can support cognitive engagement and reduce listening effort.
