The telecoil is a hearing aid component that has been used for years to help people hear on the phone and in some venues. But not until recent years has there been a movement to install induction loop technology into public buildings so hearing aid users can hear better via the telecoils in their hearing aids.
Way back in the day when Mr. Bell (among others) discovered electricity it was generated from a single source to a specific device to make it operate. However, while it took Mr. Edison’s invention to provide a practical application for the discovery, it wasn’t until Nikola Tesla discovered that winding coils of copper wire around a central core and applying an electrical power source produced an electro-magnetic field. This field emanated from the coiled wire and from there uses for electricity expanded tremendously and thousands of inventions followed.
From electric motors to telephones to auto applications, the list is endless. With micro-miniaturization, even hearing aids benefit from an electrical coil called a telecoil or T-Coil. Though tiny compared to the one pictured above, T-Coils are extremely powerful and versatile.
In our last post we discussed the benefits of wireless technology as it applies to hearing aids and also to the available accessories that make them more of a pleasure to use. There is also a growing organization that works to promote the installation of induction loops in large auditoriums like churches and theaters, etc. This is a loop of copper wire that completely surrounds a room and turns sound waves into an electro-magnetic field. The field is then converted back into sound by the T-Coils in hearing aids enabling the user to hear a speaker or music directly in their hearing aids with little to no background noise.
Although the majority of hearing instruments today are equipped with T-Coils as standard equipment there are a number of hearing aids available that don’t have them making the induction loop technology unavailable to the user. If your current hearing aids don’t have a T-coil, it could be worthwhile to consider replacing them with updated versions with a T-Coil. It could possibly be that your hearing aid has a T-Coil already and you may not be aware of it. Sometimes they just need to be activated by your hearing professional. If you have a custom hearing aid and it does not have a T-coil already, it may be possible to have one put in your hearing aid for a fee. “Will these hearing aids have T-Coils?” is a question you should be sure to ask your hearing aid provider prior to purchasing a hearing aid.
In our next blog you may look forward to learning more about other devices that can work with T-coils.
