Project title: Developing an objective measure of afferent hearing damage based on a novel type of auditory brainstem response

Sensorineural hearing damage can affect different elements of the inner ear and/or auditory nerve, such as sensory cells, afferent synapses or auditory nerve neurons. For some of these elements, damage or dysfunction may manifest as overt hearing loss, but for others, the effects on hearing thresholds may be minimal, and thus remain “hidden” to standard audiometric tests. Whilst such hidden hearing loss (HHL) may be a predominant driver of suprathreshold hearing deficits, such as difficulty understanding speech in noise, tinnitus or hyperacusis, there is currently no accepted diagnostic test for HHL. A reliable, quantitative measure for HHL would enable to assess the true state of an individual’s hearing status and help to elucidate underlying pathophysiology – a necessary precondition for developing new or individualized hearing treatments.

This project will seek to develop such a measure using a novel type of auditory brainstem response (ABR) designed to be exclusively sensitive to afferent (audiometrically hidden) auditory damage. After establishing the response’s normative properties (i.e., in young, normal-hearing subjects), we will then characterize its dependence on age and audiometric status (hearing thresholds and otoacoustic emissions, or OAEs).

This project would be particularly well-suited for graduates from audiology or life sciences with a keen interest in numeracy and computation. You will join a large and vibrant research cluster and benefit from strong supervisory and peer support. You will learn how to conduct advanced audiometric tests (including OAEs) and ABR recordings, as well as process ABRs using the cutting-edge computational and statistics tools, implemented in Matlab and R. You should have, or expect to obtain, a 1st- or 2.1-class bachelor’s, or a master, degree in a relevant scientific discipline, be self-driven and highly motivated, and have excellent communication and team-working skills. You should be eligible to apply for relevant research clearances that will be required including a check with the Disclosure and Barring Service.

How to apply:

All applications should be made directly to the University (https://www.nottingham.ac.uk/pgstudy/how-to-apply/apply-online.aspx), selecting PhD Medicine (36 months duration) as course.
