noise. This also applies to people without hearing aids who have had implants fitted to
help with hearing loss. Dr Richard Turner is looking for a solution to this problem. Although
sounds are never
20 repeated , he believes they do share some similarities. He and his
colleagues have worked on a mathematical system using
21 algorithms which replicate
how we hear sounds. To allow this system to be ‘trained’, they have applied procedures
used in machine learning and found that many different sounds can be described using a
limited number of
