John is registered blind, and relies on his hearing to get around in his everyday life. But as he has got older, he’s started to notice his hearing deteriorate. He wants to know – is there anything available in between the initial solution of wax removal, and the final destination of hearing aids? He emailed Inside Health to ask James Gallagher to investigate.

James speaks to Nish Mehta, an Ear, Nose and Throat surgeon at Royal National ENT Hospital, to find out how we hear, and learn about the different causes of hearing loss. He then visits UCL Ear Institute to undergo a hearing test with audiologist Dr Hannah Cooper, and see the potential future of hearing tests with Professor Maria Chait, an auditory cognitive neuroscientist.

But hearing in day to day life is not as simple as in a science laboratory. James meets Kevin Munro, Professor of Audiology at the University of Manchester, in a noisy café to discuss hearing aid technologies and learn about their latest advancements.
