Phonak Cognitive Well-Being

Phonak encourages a shift in the narrative from focusing solely on audibility to emphasizing the holistic benefits of hearing care, with a particular focus on the relationship between hearing health and cognitive health.

ECHHO Program

The Enhancing Cognitive Health with Hearing Optimization (ECHHO) program aims to equip hearing care professionals with resources to better integrate the topic of cognitive health into their discussions with clients.

The program will include:

  • Research findings on the relationship between hearing loss and cognition.
  • Expert guidance on how to promote cognitive health in audiological care.
  • Evidence-based explanation on the role of cognition in audiological clinical counseling.

The ECHHO program will be rolled out in Fall 2023.

Latest evidence

Phonak supports research and innovation in hearing healthcare. We are committed to driving evidence in the field of holistic hearing care and healthy aging.

The most recent studies, ACHIEVE (Aging and Cognitive Health Evaluation in Elders) and ENHANCE (Evaluation of Hearing Aids and Cognitive Effects) incorporate longitudinal observations, best practice audiological management, randomized control hearing interventions, and comprehensive cognitive assessments to provide more insight into the causal relationship between hearing loss and cognition.

Both studies were supported by Sonova’s research program and an in-kind donation of Phonak hearing aids.


The purpose of the ACHIEVE study is to determine whether best-practices hearing intervention and/or successful aging health education can slow the trajectory or prevent cognitive decline in older adults.

This study is a multi-center randomized control trial. The 977 participants were randomized to receive either hearing intervention or a healthy aging education program. 

The ACHIEVE study is led by Co-Principal Investigators Frank Lin, MD, PhD and Josef Coresh, MD, PhD from the Johns Hopkins Bloomberg School of Public Health.

Key findings

Treating hearing loss in older adults who had more risk factors for cognitive decline slowed down loss of thinking and memory abilities by 48% over 3 years. 3


In the ENHANCE study, 160 participants who received hearing intervention, including hearing aid fitting, were followed up for 3 years and their performance on a computerized battery of cognitive tests was compared to 102  participants of the Australian Imaging Biomarker & Lifestyle Study of Ageing (AIBL) who did not receive hearing intervention.

The ENHANCE study is led by Principal Investigator Professor Julia Sarant, PhD from the University of Melbourne.4

Key findings

Hearing intervention with hearing aids may delay cognitive decline and the timely management of hearing loss may facilitate maintenance of cognitive abilities.
