Hearing Aid Compatibility | Tracfone Wireless

Cell phones using acoustic coupling technology are tested for reduced RF emissions according to the ANSI C63.19 standard.

Those that are considered passing (those with a rating of "good" or "excellent") for use with hearing aids set in microphone mode are assigned a rating of M3 or M4.

Cell phones using inductive coupling technology are tested for telecoil coupling capability according to the ANSI C63.19 standard.

Those that are considered passing (those with a rating of "good" or "excellent") for use with hearing aids set in telecoil mode are assigned a rating of T3 or T4.

The higher the "M" or "T" rating, the less likely the hearing aid user will experience interference while using a cell phone.
