Hearing health matters more than you think

When we change the conversation from hearing loss as a sensory problem to hearing care as part of healthy living, we can better help patients to connect socially and thrive mentally and emotionally. Phonak supports the holistic benefits of hearing care, with particular focus on supporting responsible conversations around understanding the link between cognitive health and providing tools to care for our overall well-being.

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

Two 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 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.

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
