Phone Accessibility Information
The FCC uses a technical standard to determine whether a handset is hearing aid compatible. The newest technical standard is known as the 2019 ANSI Standard, and handsets that meet it will be labelled as “hearing aid compatible.”
Older ANSI standards used a M and T rating system that the 2019 ANSI Standard does not use. The “M” rating is for reducing interference with hearing aids operating in acoustic mode—from M1 to M4, with M4 being the best.
The “T” rating is for their ability to operate with hearing aids that contain a telecoil (a tightly wrapped piece of wire that converts sounds into electromagnetic signals) and operate in inductive coupling mode—from T1 to T4, with T4 being the best. The FCC considers a handset to be hearing aid compatible under this older standard if it is rated at least an M3 (for acoustic coupling) and at least a T3 (for inductive coupling).
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.
