Telephone Use with Hearing Aids

During the holidays, we have the opportunity to spend time our family members and friends who we might not get to see often throughout the rest of the year. Why not enhance your daily communication with those close to you by improving hearing ability on the telephone? Understanding speech on the phone is a significant area of difficulty for the majority of individuals with hearing loss.
Our ability to understand speech is augmented by the cues provided by looking at someone’s face when they are talking and by binaural listening (hearing with two ears). Communication via the telephone can be extremely difficult due to the loss of visual cues and relying on only one ear. In the past, individuals with hearing aids may have experienced whistling when attempting to use the telephone in conjunction with their hearing aid. The technology available today allows for improved telephone communication.
Hearing aids can now come equipped with a telecoil to improve telephone use. The telecoil circuit allows for electromagnetic communication between the telephone and the hearing aid by positioning them appropriately close together – a program button can be provided on the hearing aid if an individual has difficulty with maintaining the position of the phone. How do you obtain the most optimal telecoil response with a hearing aid? Your landline phone should have at least a 100 milliamps per meter (mA/m) magnetic strength in order to achieve a good connection to the hearing aid telecoil. If your phone is not emitting a strong enough magnetic field, a magnet can be placed on the phone receiver. Cell phones should have a minimum of a M3/T3 rating. The M refers to use with the hearing aid microphone; whereas the T refers to the use with the hearing aid telecoil. The higher the rating, the better compatibility is with the hearing aid – M4/T4 provides the best compatibility.
Even more exciting … some of the hearing aid manufacturers have recently developed technology that allows the hearing aid to automatically send the telephone response to both hearing aids simultaneously to regain the binaural listening, which is lost with traditional telephone use. In addition, many hearing aids are Bluetooth compatible to allow for hands-free cell phone use without having to take out the hearing aids to use a hands-free Bluetooth device for the cell phone while driving.
Individuals with a more severe degree of hearing loss may require use of a captioned telephone or phone relay service. Captioned telephones have a visual display of every word that the person you are communicating with to improve your ability to understand speech on the phone. IP Relay Service is available for individuals who use American Sign Language as their primary means of communication to allow for telephone communication.
Remember to enjoy your holiday season and keep in touch with the ones you love!
