Phone Accessibility Information

The Federal Communications Commission (FCC) has passed a set of rules located under 20.19 (h) that is designed to make mobile phones more accessible to persons with disabilities. The FCC then created 2 rating system to help consumers with hearing disabilities find a phone that will work with their hearing aids. These rating systems are rated under an M value and a T value.

Wireless phones rated “M3” or “M4” meet the FCC requirements for hearing aid compatibility. The “M” refers to using the phone with a hearing aid in the microphone setting. The higher the “M” rating, the more likely it is you will be able to use the phone with your hearing aid on the microphone setting. Thus, M4 is the “better” or higher of the two ratings.

The “T” rating refers to using the hearing aid set on the telecoil. The higher the “T” number the more likely you will receive better interoperability performance between your phone and hearing aid in the telecoil setting. Thus the T4 is the “better” or higher of the two ratings. Reduced feedback and reduced background noise are additional benefits of using a hearing aid set on telecoil during phone use.

Below we have created a chart that gives the hearing aid values. For more info on any phone please call our business office or visit the manufacturer’s website for the most recent updated information.
