FCC HAC Information

Hearing Aid Compatible

The use of some wireless devices near some hearing devices (hearing aids and cochlear implants), may cause users to detect a buzzing, humming, or whining noise. Different hearing devices have different levels of immunity to this interference noise, and wireless devices also vary in the amount of interference they generate. In the event of this type of interference, a user should consult their hearing device supplier to discuss solutions.

The wireless device industry has developed a rating system to assist hearing device users in choosing compatible wireless devices. Zebra offers a number of wireless devices designed, tested and certified to potentially improve performance for users with hearing devices.

ANSI C63.19 Rating System for Wireless Devices

M-Ratings: wireless devices rated M3 or M4 meet FCC requirements and are likely to generate less interference than devices not labeled with an M rating. M4 is the better/higher of the two ratings.
T-Ratings: wireless devices rated T3 or T4 meet FCC requirements and are likely to be more usable with a hearing device’s telecoil (‘T Switch’ or ‘Telephone Switch’) than unrated devices. T4 is the better/higher of the two ratings. (Note: Not all hearing devices have telecoils.)

Hearing devices may also be measured for immunity to this type of interference. A user’s hearing device manufacturer or hearing health professional can assist in finding information for a specific hearing device. A hearing device with greater immunity to interference will be less likely to cause a user to experience interference noise from wireless devices.

Non-interference cannot be guaranteed. Results vary depending upon the hearing device and the user’s hearing loss. If a hearing device is vulnerable to interference, the user may not be able to use a compatible-rated wireless device successfully. Trying out a wireless device with a user’s hearing device is the best way to evaluate requirements for a user’s personal needs.
