Somehearing devices are more immune than others to this interference noise, and phonesalso vary in the amount of interference they generate.The wireless telephone industry has developed ratings for some of their mobilephones, to assist hearing device users in finding phones that may be compatiblewith their hearing devices. Not all phones have been rated. Phones that are ratedhave the rating on their box or a label on the box.The ratings are not guarantees. Results will vary depending on the user’s hearingdevice and hearing loss. If your hearing device happens to be vulnerable tointerference, you may not be able to use a rated phone successfully. Trying out thephone with your hearing device is the best way to evaluate it for your personalneeds.M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely togenerate less interference to hearing devices than phones that are not labeled. M4 isthe better/higher of the two ratings.
