Plain English Summary
Background and study aims
Current mobile telephone technology reduces the range of sounds transmitted, which is considered to be acceptable to users with normal hearing. However, it's a known issue that hearing impaired individuals can be negatively affected by this. Goshawk is developing a medical device which Goshawk believes can improve the user experience. Previous trials in a laboratory setting showed 70% of users expressed a preference for the Goshawk-processed audio compared to standard mobile phone calls. This study aims to show that using the device in a commercial mobile phone network improves the user experience of mobile telephone calls.
Who can participate?
Men or women with a known or suspected hearing impairment.
What does the study involve?
Participants are given access to the Goshawk service, which consists of a web-based hearing assessment tool and a real-time audio compensation service applied to the user's mobile telephone (via the Goshawk SIM). The sound enhancement is based on the user's hearing test results, from the web-based hearing assessment tool.
What are the possible benefits and risks of participating?
The possible benefits are improved audio quality on mobile telephone calls, resulting in an improved user experience. There are no known side effects to the use of this service, in conjunction with the standard mobile telephones available on the market.
Where is the study run from?
The study will be run from the Goshawk offices in Compass House, Isle of Man.
When is the study starting and how long is it expected to run for?
Recruitment for the study has provisionally started. The intervention part of the study is due to commence on 1st May 2018 and is expected to run for 4 to 8 weeks. Recruitment will continue until the target number of users is between 50 and 100.
Who is funding the study?
The study is being funded by a combination of Goshawk, Isle of Man Government Department of Health and Social Care and Manx Telecom.

Intervention
Upon commencement of the trial, users will be granted access to the Goshawk product, which delivers real-time audio enhancement over communications networks (initially to mobile telephones, but also applicable to fixed telephony or VoIP applications). Thereafter, any and all calls made using the Goshawk service (via an enabled SIM in their mobile telephone) will be subject to intervention, until the end of the trial (either by normal expiry, or by a user request to leave the trial). The device enhances the user experience of mobile telephone calls

Primary outcome measures
User experience measured by an online questionnaire and audibility testing at baseline, at start of service activation, after 4 weeks of use and after deactivation of the service. The audibility test will be conducted by a trial administrator who will conduct verbal testing over the telephone (with the service active), utilising 'Harvard Sentences' (as developed by the IEE, a series of phonetically balanced sentences). The user will be asked to repeat the sentence to the administrator. The first three timepoints will involve testing using 3 of 10 sentences. The last timepoint will use all 10 sentences.
Secondary outcome measures
Improved user experience of mobile telephone as measured by call time/frequency increase.
