Study period


Each year in the UK, around 7,500 people are affected by single-sided deafness (SSD). That is, when there is a substantial hearing loss in one ear and little or no hearing loss in the other ear. Individuals with SSD can use one of several hearing-assistive devices to help aid their listening abilities. Some devices simply re-route sounds from the deaf ear to the hearing ear. Other devices attempt to restore hearing in the deaf ear.

There is currently very little research which has studied the impact of SSD on health and well-being. We also have a poor understanding of whether the various hearing-assistive devices for single-sided deafness improve the health of individuals with SSD.

This study aims to improve our understanding of SSD and its impact on the quality of people’s lives. We aim to achieve this by working with people who have direct experience of SSD and clinicians with experience of treating those with SSD.

Describing health conditions in this way is central to recognising what hearing services are needed to assist those with SSD and to justify their provision on the NHS. It also helps us to understand whether current treatments for SSD are helpful to patients, how we should measure the benefits of any new treatments that come along in the future, and what those with SSD think are the most important problems that future treatments should target.

We would like to hear from anyone who may be interested in taking part in this research:

Do you have SSD or know someone who does?
Are you a Clinician who has knowledge of the function and impact of devices used to aid SSD?
