About Hearing Aid Compatibility

As wireless carriers move from analog to digital services, accessibility for the deaf and hard of hearing is a concern. Digital technology means more features and improved efficiency -- but some digital phones can cause interference for hearing aid users.

To make sure the deaf and hard of hearing can use digital wireless devices, the Federal Communications Commission (FCC) updated the Hearing Aid Compatibility Act of 1988 ("HAC Act"), passing regulations to increase the number of hearing aid-compatible wireless devices.

Along with many others in the wireless industry, we strive to ensure accessibility for all individuals, including deaf and hard of hearing consumers.

  • M-Ratings and Hearing Aid Immunity

    Phones with an M-Rating of M3 or M4 meet FCC requirements and are less likely to generate interference to hearing devices than phones that are not labeled. M4 is the better/higher of the two ratings.

    Hearing devices may also be measured for immunity to this type of interference. Your hearing device manufacturer or hearing health professional can help you find results for your hearing device. The more immune your hearing aid is, the less likely you are to experience interference noise from mobile phones.


  • T-Rating and Compatibility with Hearing Aids with Telecoils

    A telecoil is a small device that is built into some hearing aids for use with the telephone as well as assistive listening devices. Not all hearing aids have telecoils. Phones with a T-Rating of T3 or T4 meet FCC requirements and are more likely to work well for people who use hearing aids with telecoils with telephones. T4 is the better/higher of the two ratings.

Try Before You Buy
