PhD Studentship - Non-linear Cochlear Mechanics: Models and Measurements

Supervisory team: Ben Lineton

Project description

The mechanical response of the cochlea to sound exhibits an intriguing array of different non-linear phenomena, involving interactions across time and frequency. These remain poorly understood but can be assessed using otoacoustic emissions (OAEs): low-level sounds detectable in the ear canal.

OAEs are measured by presenting sound stimuli to the ear and measuring the response.

Though they are currently used in certain clinical applications (such as diagnosing cochlear impairments in newborn babies), many questions remain:

• How do features in the OAE signal relate to processes and pathologies within the cochlea?
• What is the optimum stimulus and recording method for assessing different cochlear impairments in different patients (e.g., children)?

This project will explore:

• Mathematical models of non-linear cochlear mechanics that underly the generation of different classes of OAEs.
• The design of stimulus and recording paradigms to optimise clinically relevant features of OAEs.
• Measurements of OAEs in human volunteers using different recording paradigms.

Entry Requirements

A very good undergraduate degree (at least a UK 2:1 honours degree, or its international equivalent).

Closing date: applications should be received no later than 31^st August 2024 for standard admissions, but later applications may be considered depending on the funds remaining in place.

Funding: Funding for tuition fees and a living stipend are available on a competitive basis. Funding will be awarded on a rolling basis, so apply early for the best opportunity to be considered.
