Guide to coping with hearing aid feedback
Assistive Listening Devices ALDs are personal technologies that can help you communicate in one-to-one conversations. They are hand-held amplifiers with microphones that bring the sound you wish to hear closer to your ears. These small devices capture the sound you want to hear and may filter some background noise.
A Pocketalker is an inexpensive, wired, example of this type of device. There are other personal devices, such as wireless FM devices and propriety devices that are sold by audiologists as ancillary equipment to various brands of hearing aids and cochlear implants. An example of how you might use this type of device is communicating with a family member at a large family gathering.
Your family members speak one at a time into the microphone, and the sound is transmitted to your hearing device reducing competing noise, so you can understand them more clearly.
Several types of Assistive Listening Devices ALDs are available to improve sound transmission for people with hearing loss. Some are designed for large facilities such as classrooms, theaters, places of worship, and airports.
Other types are intended for personal use in small settings and for one-on-one conversations. All can be used with or without hearing aids or a cochlear implant. Assistive Listening Systems ALSs are the gateway through which people with hearing loss access the sound being transmitted through a public address system or sound system.
If a person wants to conveniently connect to one of these systems, it is useful for their hearing device have a telecoil. ALS for large facilities include hearing loop systems , frequency-modulated FM systems , and infrared systems.
All assistive listening systems should be usable by people with hearing aids, with hearing aids but no telecoil, and without hearing aids. People who do not have hearing-aids and people do not have telecoils in their hearing aids can use a hearing loop, FM or IR system if they have a receiver that is connected to headphones. Hearing Loops or Induction Loops consist of a copper wire place around a room, theater or counter which is connected via a special loop driver to a public address or sound system.
An electromagnetic field is created that connects to a telecoil in hearing aids, cochlear implants or telecoil receivers. Hearing loops are simple, discreet and effective. Users simply switch their devices to the telecoil program and automatically receive clear customized sound directly to their ears.
People who do not have hearing aids or who do not have access to telecoils in their hearing aids or streamer need to use a hearing loop receiver and headphone to connect to the system. For more information, go to our Hearing Loop Technology page. A telecoil, also called a t-coil, is a wire that is installed inside many hearing aids and cochlear implants to act as a miniature wireless receiver.
It was originally designed to make sounds clearer to a listener over the telephone. It also is used with a variety of other assistive listening devices, such as hearing loop or induction loop systems, FM systems, infrared systems, and personal amplifiers. Telecoils expand the usefulness of hearing aids and cochlear implants , especially in environments where it is typically challenging to hear clearly. Telecoils, also called t-coils, are built into many hearing aids, all cochlear implants and some streamers.
T-coils are an essential component for anyone wishing to easily and directly access an assistive listening system. The telecoil works by receiving an electromagnetic signal from the hearing loop and then turning it back into sound within the hearing aid or cochlear implant.
Many cochlear implants have a telecoil built into the sound processor, or can use an external telecoil accessory with both hearing aid compatible telephones and public loop systems. A simple switch or programming maneuver performed by the user activates this function.
When being fitted for a hearing aid, insist that it include a telecoil. For cochlear implants, ask for the telecoil feature to be activated. For the first time since I lost most of my hearing, I went to a musical performance and used a hearing loop.
The live music was perfectly clear, perfectly clean and incredibly rich. How many Americans live with hearing loss? According to the National Institute on Deafness and Other Communication Disorders, there are more than 36 million Americans with hearing loss, 10 percent of the U.
Why are hearing loops needed? Yet, for many people with hearing loss, the sound becomes inaudible and unclear when live speakers or recorded broadcasts are at a distance, there is room noise, and when room acoustics cause reverberation of sound. A hearing loop electromagnetically transfers sound signals directly to hearing aids and cochlear implants equipped with a telecoil t-coil receiver.
How many hearing aids have the telecoil necessary to receive hearing loop input? If the 51 completely-in-the-canal aids are not included, the percentage increases to In a recent survey, 84 percent of HLAA members reported having t-coils in their hearing aids.
All new cochlear implant models now have t-coils. The Guide can be found at hearingloss. Can hearing loops serve those without telecoils or without hearing aids or cochlear implants? Yes, like other forms of assistive listening systems, hearing loops come with portable receivers and headsets for those who do not have telecoil-equipped hearing aids. What does a hearing loop cost?
Cost considerations must factor in the size of the space and building design of designated venue to be looped. There is no cost to the user with telecoil-equipped hearing aids. Hearing loops harness magnetic energy. So, is magnetic interference problematic?
There are two concepts to consider: 1 Magnetic interference caused by the room loop itself; 2 Stray electromagnetic interference EMI in the room caused by other sources that can interfere with the use of telecoils worn by the listeners. Hearing loops emit a magnetic field which can create potential for interference with electronic equipment. However, if the loop is installed correctly meeting international standards IEC this will be avoided.
Stray EMI is caused by old non-flat computer monitors, old fluorescent lighting, old dimmer switches, transformers, and motors. This EMI has the potential to adversely affect the ability of the telecoil receiver to receive a good signal from the loop. It can cause distortion that will be heard when the telecoil is active.
This can also happen using a telecoil with a hearing-aid-compatible phone. Interference-free installation is nearly always possible if done correctly and adhering to standards. Like electronic computers, magnetic induction loop technology began more than half a century ago. However, it enjoys a new form with new amplifier technology and new computer-modeled designs for complex installations.
It can also be used with wireless microphones to hear one or more companions at home, in the workplace, and while traveling. It is very portable. However, it is expensive, is limited to a 30 foot range, and will not allow you to couple connect to a large-area listening system such as a loop, FM or IR system. To connect, you need a telecoil inside the hearing aid or cochlear implant.
This circuit does not add any cost to the hearing aid or cochlear implant and provides an easy and discrete way to hear via a loop system. The user simply activates the telecoil on the hearing aid or cochlear implant and walks into the looped room and begins to hear. Bluetooth is a relatively short-range wireless technology frequently used to connect cell phones, televisions, computers, tablets and, recently, hearing aids and cochlear implants.
Hearing device Bluetooth technology is sometimes proprietary—that is, designed for a specific brand and or model of device. While this technology is evolving, it is still generally not suited for long-range transmission in a large venue like an auditorium or theater. Can hearing loops be used in adjacent rooms? Yes, with professional design that controls sound spillover. Are there advantages to using hearing loops for home TV listening and in public settings?
A hearing aid or cochlear implant compatible loop system delivers sound that is customized to individual listener needs. Telecoil only is desired when the listener wants to hear only what is coming through the loop and not the outside world. It also allows the listener to hear and monitor his or her own voice. This is especially important for people with more severe hearing loss. The main advantage to using a hearing loop system is that all the listener needs to do is activate the telecoil — there is no extra equipment required.
Can hearing loops work in transient venues such as airports, ticket windows and drive-up order stations? How do you know if the venue is looped? The New York City Transit Authority, for example, has installed hearing loops at subway information booths. All the listener needs to do is switch the hearing aid or cochlear implant to the telecoil mode. What if the loop does not seem to be working? Like any technology, systems require periodic checking.
If properly installed and checked, hearing loops require little or no maintenance to work reliably. The listener also needs to periodically check that the t-coil function on the hearing aid or cochlear implant is operating efficiently and programmed according to user needs. Who makes hearing loops and where can they be purchased? A variety of American and European manufacturers are designing and marketing hearing loop amplifiers for a wide variety of installations in the home, workplace, theater, house of worship, transportation, health care, and education settings.
Hearing Loss Prevalence in the United States. An advantage of this system over an infrared system is, it is not affected by direct sunlight. A disadvantage is, it offers less confidentiality because the signals cannot be contained within a given space.
For those who have telecoil-equipped hearing aids and cochlear implants, neck loops eliminate the need for headphones. A transmitter sends speech or music from a public address or sound system to an IR receiver using invisible infrared light waves. This technology is line of sight and cannot be used outdoors during the daytime due to being affected by light.
Because IR signals are sent and received in a straight line, users are encouraged to sit as centrally as possible; those sitting in balconies or other areas with poor sight lines may experience interference or receive no sound signal at all.

Not Ready for a Hearing Aid But Need a Little Help?
Explore our range of modern hearing devices, learn about our ever-expanding technology, and find the hearing aid that will help you reconnect with the things and people you love. Hearing aids are small but powerful electronic devices designed to discreetly assist your hearing. Powered by batteries, hearing aids include three essential parts: the microphone, amplifier, and speaker. Through the microphone, sounds in your environment are picked up and converted into a digital signal. The amplifier increases the power of the signal, which is then sent into your ear through a speaker also known as a receiver.

Most patients develop tinnitus as a symptom of hearing loss, caused either by age, long-term hearing damage, or acute trauma to the auditory system. According to the general scientific consensus, hearing loss causes less external sound stimuli to reach the brain. In response, the brain undergoes neuroplastic changes in how it processes different sound frequencies. Tinnitus is the product of these maladaptive neuroplastic changes. Patients with hearing loss and tinnitus may find relief from the use of hearing aids and other sound amplification devices. Hearing aids are small electronic devices worn in or behind the ear. Hearing aids can augment the volume of external noise to the point that it covers masks the sound of tinnitus. This makes it more difficult to consciously perceive tinnitus and helps the brain focus on outside, ambient noises.
