It is well-established that high levels of noise exposure can lead to hearing loss and tinnitus (i.e. a ringing or buzzing in the ears). It has also been suggested that noise from modern urbanised society is sufficient to cause some degree of “hidden” or sub-clinical hearing damage which is not readily detected using conventional hearing tests. However, there is also some research to suggest that low-to-medium levels of noise exposure may help to “toughen-up” the ears so that they are less susceptible to damage from subsequent high levels of noise exposure. This could explain some of the variability in individuals’ susceptibility to noise-induced hearing problems, where previous noise exposure earlier in life may serve to have a protective effect. Nevertheless, the precise mechanisms and timescale of this toughening effect remains to be determined, and it is unknown how long-lasting this toughening effect is after exposure to noise or after a period of prolonged quiet time, nor what is the precise “dose” of noise exposure required to develop this toughening of the ears. It is also possible that other factors such as the type of noise (i.e. pleasant vs unpleasant), cognitive abilities such as selective attention, and auditory processing skills, may provide a “top-down” contribution to this toughening effect.
This project aims to explore the different effects that noise exposure can have on our hearing, from early childhood up until older age, while also accounting for factors such as cognitive and auditory processing skills. The project will involve a variety of different experimental methods including questionnaires and interviews, auditory psychophysical testing, clinical audiological measures, cognitive testing and electrophysiology.
Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree (or equivalent) in a related area/subject. Candidates with previous laboratory experience, particularly in cell culture and molecular biology, are particularly encouraged to apply.
