Are My Hearing Aids Compatible with My Cell phone?
wearing hearing instruments can struggle occasionally with hearing on their
cellular phones. Firstly, if you are purchasing a new mobile phone, you
may want to investigate the phone model of interest for its Hearing Aid
Compatibility (HAC) rating. Most of the newer cellular phones are HAC.
The Federal Communication Commission (FCC) defines hearing aid
compatibility based on two parameters, the radio frequency (RF) and
telecoil (T-coil) coupling (T). Hearing aid compliant mobile phones are marked
and ranked with an “M” or “T” rating. The “M” rating refers to the
microphone modes or RF emissions and the “T” rating refers to the T-coil
mode. The minimal standard required by the FCC for a cellular phone to be
considered hearing aid compatible is M3 and T3. If you are considering a mobile
phone with a T rating, you will want to confirm with your audiologist that your
hearing instruments have a T-coil. Once you have confirmed the availability
of a T-coil, you will also want to ensure that it is activated in your hearing
instruments. The activation of the T-coil in your hearing instruments
will aid the “T” rated cellular phone’s ability to couple with your hearing
instruments. The higher the “T” rating, the more likely you will have a
stronger T-coil connection between the mobile phone and your hearing
instruments. The T-coil connection allows for increased volume in the
hearing instruments while on your cellular phone without having to worry about
“whistling” or feedback. If you are curious about your T-coil instrument
compatibility with your cellular phone, contact your audiologist today. Another way hearing aids can be compatible
with cellphones is through direct connection via Bluetooth in the hearing aids,
also known as direct connectivity. In
order to utilize direct connectivity, your cellphone must have Bluetooth capabilities. Both Smartphone options, Iphones and Android phones, have options for direct connectivity to the Phone for phone calls.
