Maximizing the slope of the psychometric function for speech-in-noise tests

The psychometric function measures how performance varies with speech level in a speech-in-noise task. It runs from chance to perfect via threshold. Its slope defines how much percent correct is gained per decibel of speech level. In general, the steeper the slope the better; a steeper slope ought to allow a higher resolution of test, which is needed to enable the detection of finer changes in performance that might be an early marker of a future hearing loss. The goal of this project is to research new methods to make the slope as steep as possible. It's quite easy to make a slope shallow but making it steep could be quite a challenge.

 You will learn about speech-in-tests, comparison of different signals and background sounds (and their construction), psychometric methods and signal detection theory. There will be scope for experimental research using normal-hearing and hearing-impaired participants and developing computer simulations of performance.

 You should have or expect to obtain a first class or upper 2.1 honours degree (or equivalent), or an MSc/MA, in neuroscience, psychology, audiology or other relevant scientific discipline. Research experience in auditory research will be an advantage. You will have excellent communication and team-working skills, be self-driven and highly motivated. You should also be eligible to apply for relevant research clearances that will be required including a check with the Disclosure and Barring Service.

The successful applicant will join a large and vibrant research cluster and benefit from strong supervisory and peer support.
