Do EMFs present a problem for hearing aids?
The power used by hearing aids is very small, there are few mains-frequency EMF problems associated with their use as far as we are aware. If switched to inductive loop mode, hearing aids can buzz close to high power electricity cables or transformers. Hearing aids are often sensitive to microwaves, especially digital pulsing ones such as are emitted by GSM mobile phones and base stations. These can cause buzzing noises and a high pitched whine. Wireless Local Area computer networks can cause clicking / scratching sounds, as can some 3G mobile phone systems. The hearing aids should be protected by good design, but often aren’t.
