To ensure everyone benefits from advances in technology, the Federal Communications Commission ("FCC") has approved standards and passed regulations for digital wireless device use with hearing aids. In 2001, the FCC modified the exemption for wireless phones under the Hearing Aid Compatibility Act of 1988 in light of the rising number of wireless calls to emergency services and the growing trend among wireless carriers to move away from analog services in favor of more efficient and feature-rich digital services.
The FCC defines Hearing Aid Compatiblity (HAC) for cell phones in terms of two parameters; radio-frequency (RF) emissions and telecoil coupling. HAC-compliant device packages are marked with "M" or "T" ratings. The M-rating refers to the microphone mode. The T-rating refers to the telecoil mode. Only phones that meet HAC compliance will be labeled as such. If you see a "M3", "M4", "T3" or "T4" on the box then the phone has been designated as HAC compliant. Cell phones that comply with the FCC's hearing aid compatibility rule must receive a minimum rating of M3 for RF emissions and T3 for telecoil coupling.
