Support us Participate in our research Seeking research participants with standard hearing Do you often struggle to understand someone when there is noise around or over a distorted phone line? We call this “listening effort”, and it leads to tiredness and reduced quality of life. This is especially a problem for those with hearing loss. If we could measure listening effort then we would be able to find out which hearing aid designs and programmes reduce listening effort the most, and therefore maximise the benefits obtained from the hearing aids. In this project, we will develop a new way of measuring listening effort using near infra-red light.
