This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


Bone conduction devices (BCDs) are hearing aids which are given to people with a mixed or conductive hearing loss to improve their hearing. These devices deliver sounds to the patient by sending vibrations through the skull to stimulate the hearing organ. This study is looking to see if patients with a smaller degree of mixed or conductive hearing loss than would normally be considered for a BCD also benefit from a BCD when we compare their speech understanding with their conventional hearing aid.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

24 Jun 2024 30 Sep 2026

Participants will be invited to two appointments at the hospital. At the first appointment an audiologist or a member from the research team will talk through the study and ask the participant to sign a consent form. A hearing test and some listening tests with the participant's current hearing aid(s) will be conducted. In addition, the participant will fill in some questionnaires about how they are feeling, and how well they are listening with their hearing aid(s). The local audiologist who is part of the research team will then fit a BCD on a softband for the participant to try out for 2 weeks. In about 2-6 weeks, the participant will come back to the hospital once for some more listening tests, this time with the BCD fitted in the previous appointment. A few more questionnaires on how listening with the BCD was and how it was different to their regular hearing aid(s) will also be filled out by the participant.


Adults (18 years of age and above) who are willing and able to provide written informed consent and are air conduction hearing aid (ACHA) users (including bilateral hearing aid users) with a recent fitting (<6 months)

You can take part if:



You may not be able to take part if:


1. Inability to wear ACHA consistently2. Inability to perform English speech tests and complete questionnaires independently3. Rapidly changing or fluctuating hearing loss

During the study period we do not anticipate any problems, but if any occur you can contact your local department for advice. The study hearing aid is fitted on a softband, which may or may not cause some discomfort when worn for a longer period of time.
