Campaign to get hearing loops working Hearing loops, systems which helps clarify sound for people who are hard of hearing, often don't work according to a charity. Installed into buildings such as shops and theatres they direct sound and speech directly into hearing aids and cochlear implants. Hearing Link says loops often don't work or staff have not been trained in how to use them. Graham Satchell travelled to Eastbourne, where they are aiming to be a beacon of excellence for hearing impaired people.
