Hearing Aid Static with Cell Phone
Its not uncommon for hearing aid users to experience some level of interference when using cell phones. Unfortunately, there is no one easy solution for this problem. Interference may occur with all cell phone manufacturers as well as with all hearing aid manufacturers. The interference is usually caused by either radio-frequency or low frequency baseband signals, but could also be caused by light ballasts and walkie-talkies in the area. But you should first figure out if it is cell phone interference or hearing aid feedback or whistling.
If it is feedback then you should contact your Hearing Care Professional for solutions. If it is cell phone interference then the best suggestion is to simply try different phones and different carriers until you find one that works best for you. In the United States three different technologies are used for transmission (CDMA, TDMA and GSM) and one may work better with your particular hearing aid. Contact your cellular service provider and they can tell you which technology they are using. If you are unable to find a phone that works to your satisfaction you may want to consider using an additional accessory, such as a neckloop. This works through the telephone coil of your hearing aid and lessens the interference because you are increasing the distance between the hearing aid and the phone. Several cell phone manufacturers offer this option with some of their models. You should be aware that there is hope for better compatibility in the future. The FCC recently passed a ruling requiring cell phone manufacturers to produce at least a few phones that have significantly reduced interference within the next few years.
