My friend wears a hearing aid – can he use a mobile phone?
Most new models of hearing aids are immune to radio frequency interference from GSM phones that are more than 2 metres away. Some are also immune to interference when the phone is brought up to the same ear as the hearing aid. The result depends on the level of immunity designed into the hearing aid, the nature of the hearing loss and the type of mobile phone. Unfortunately many types of older hearing aids may be susceptible to interference making it very difficult to use a mobile phone.
