Users of hearing aids often experience disturbances due to EMI (electromagnetic interference) from various types of electrical devices including digital mobile phones.

 

The rapid pulsation of radio signals from digital mobile phones can give rise to a buzzing, humming, squealing, or squelch inside the hearing aid for the user. The level of interference depends primarily on the electromagnetic immunity of the hearing aid, but also on the type of mobile phone, its output power and the separated distance to the hearing aid.

 

To improve this compatibility between digital phones and hearing aids Sony-Ericsson, along with manufacturers of hearing aids, and independent research centers are conducting joint projects and studies to reduce the effects of interference.

 

Analog phones provide the least risk of any electromagnetic interference that might be picked up by the users hearing aid.

 

For digital mobile phones, a person wearing a hearing aid should use the Hands-Free devices to enable them to use the phone without placing the phone at their ear, thus avoiding the risk of disturbance in the hearing aid.
