Cortical sensitivity to binaural amplitude-modulated sounds

Each year at the British Academy of Audiology conference, nearly 100 posters are presented about the latest research projects that have been undertaken. Prizes are awarded by a panel of judges and this year there were joint winners. The following report is from one of the winning projects that looked at cortical sensitivity.
