In our office, we counsel all our patients on the different types of Assistive Listening Devices (ALDs). While patients hear much better with well-fitted hearing aids, there are still unavoidable scenarios in which even the most cutting-edge technology may not be enough.
What are Assistive Listening Devices (ALDs)
- Assistive listening Devices (ALDs) can be used with or without hearing aids. They help reduce background noise, enhance sound clarity, and improve communication.
- When hearing aids alone do not help, assistive listening devices help fill the gaps. They improve speech clarity and reduce background noise in challenging environments like theaters, classrooms, public spaces, and at home.
- Assistive listening devices come in many forms to match different needs. From amplified phones and TV streamers to FM systems, hearing loops, and alerting devices, these tools support communication, safety, and independence for people with hearing loss.
- An audiologist can help you choose the right technology to work with your hearing aids and lifestyle.
Hear Better in Public Places
Public spaces can be challenging for people with hearing loss, but assistive listening devices make it easier to understand speech and stay engaged. Whether you’re attending a concert, worship service, or city council meeting, ALDs help bridge the communication gap.
Induction loops, FM systems, and other sound processors cut through background noise, making it easier to hear in group settings. These assistive listening systems are vital tools for inclusion, access, and better communication.
As audiologists, we often recommend ALDs as part of a complete hearing care plan. While hearing aids are the first step, ALDs provide significant support in specific settings where even advanced hearing aids may struggle.
ALDs are helpful for people of all ages and hearing levels, especially those who attend events, travel, or work in public spaces.
What Types of Assistive Listening Devices (ALDs) Are Available?
Telecoil or T-Coil:
A telecoil (also known as a t-coil) is a small copper wire inside many hearing aids and cochlear implants. It allows the hearing instrument to pick up magnetic signals directly from compatible devices, such as phones or loop systems, bypassing the microphone.
When activated, the telecoil eliminates background noise and improves speech understanding.
Not all hearing aids have t-coils, but they’re available in many models. Talk to your audiologist to see if your hearing aid includes a telecoil and how to use it in everyday situations. It’s a small feature that can make a big difference in sound quality and access.
As you will read below, there are several ways to access a T-coil.
Amplified Telephones:
Amplified phones increase the volume of incoming calls to help users hear voices more clearly. These phones often come with tone control to improve speech clarity and have extra-loud ringers to make sure you don’t miss a call. Some models can be used with hearing aids using telecoil (t-coil). Amplified phones are simple to use and highly effective.
Hearing Aid Compatible Phones:
Hearing aid-compatible phones are designed to work well with hearing aids and cochlear implants. These phones reduce interference and feedback and are equipped with t-coils or digital wireless technology to transmit sound more clearly.
Most modern smartphones are HAC-rated, and the Federal Communications Commission (FCC) requires mobile phone providers to offer hearing aid-compatible options. These phones use radio signals, induction, or Bluetooth signals, to send sound directly to hearing aids or listening devices.
Whether for personal or professional use, a hearing aid-compatible phone improves communication and makes phone calls easier for anyone wearing hearing aids or listening devices.
Assistive Listening Devices for Television:
Television can be difficult to enjoy when speech sounds are unclear or the volume is too loud for others in the room. ALDs for TV are assistive listening devices that stream audio directly to your hearing aids, listening devices, or headphones.
These systems may use Bluetooth, infrared, or radio waves to send sound to the listener. Many models include individual volume controls and work with or without hearing aids. Some connect through a base station at the TV, while others pair wirelessly. With increased clarity TV listening becomes more enjoyable and accessible.
FM Systems for Public Settings:
FM systems are widely used in classrooms, churches, theaters, and meeting halls. These assistive listening systems use radio signals to send sound from a speaker’s microphone directly to a receiver worn by the listener. The receiver can be a hearing aid, listening device, or headphones.
FM systems reduce background noise and make speech clearer, especially in large or noisy spaces. Teachers, tour guides, and public speakers often wear a transmitter microphone, while listeners use a portable receiver with headphones, hearing aids or listening devices.
For individuals with communication disorders or moderate to severe hearing loss, FM systems help bridge the gap in public communication and offer a more inclusive listening experience.
Alerting Devices:
Alerting devices use flashing lights, vibrations, or loud sounds to notify people about important events. These can include alarm clocks, doorbells, baby monitors, smoke detectors, or phone ringers.
They’re especially helpful for people who don’t wear hearing aids at night or in quiet settings. Many systems connect to a central base that alerts users with a visual or vibrating signal. For example, a vibrating alarm clock placed under a pillow can wake someone up safely, while flashing lights may signal a visitor at the door.
Alerting devices play a vital role in the safety and independence of those with hearing loss.
Inductive Loop Systems
Induction loop systems, also called hearing loops, are a type of assistive listening technology found in many public spaces. A loop of wire installed around a room transmits sound directly to hearing aids equipped with a telecoil (t-coil).
This creates a direct, clear connection that filters out background noise. Hearing loops are popular in theaters, churches, auditoriums, and even taxis. Users simply switch their hearing aids to the “T” setting to hear the speaker clearly.
Why Are Assistive Listening Devices Necessary?
Even the best hearing aids can struggle in complex listening environments. Assistive listening devices provide targeted support by improving signal-to-noise ratio, enhancing speech clarity, and offering more control in challenging situations.
They allow people with hearing loss to participate more fully in social, work, and public settings. Whether through a loop system in a theater or a personal amplifier at dinner, ALDs improve the quality of life for people with hearing loss.
Are Assistive Listening Devices Required?
In many public venues, yes. According to the Americans with Disabilities Act (ADA), certain public spaces must provide assistive listening systems, especially where audio communication is essential.
Facilities like courtrooms, conference centers, theaters, and public transit hubs are required to offer some form of assistive listening for people with hearing loss. This often includes induction loops, FM systems, or infrared devices.
Compliance helps ensure that people with hearing loss can access the same information and experiences as others. For businesses and public institutions, having these systems in place is not just helpful—it’s the law.
If you manage a venue or business, consult with an audiologist or hearing specialist to determine the best system for your space.
Where Can I Get More Information About ALDs?
To learn more about assistive listening devices, hearing loops, and telecoil-compatible technology, speak with an audiologist. They can guide you through available systems, show you how they work, and help you choose the best options for your lifestyle and needs.
You can also try ALDs in-clinic to see how they complement your hearing aids or other listening devices. Whether you’re new to hearing instruments or seeking better sound support, there’s an assistive technology solution for you.
