Patient Care | June 2018 Hearing Review
A review of hearing aid/ALS compatible systems, as well as how and where to find them
There’s no doubt about it: hearing aids change lives. Families are reconnected, employment is preserved, and social activities are enjoyed once again. Hearing aids give back the valuable connection that sound offers us. With the recent advancements in hearing aid technology like Bluetooth connectivity, noise cancellation, wind reduction, and customizable apps, users are increasingly satisfied with their investments in their hearing health.
Radio frequency, infrared, hearing loop, and Wi-Fi streaming audio systems are all applicable for hearing aid users. Here is a brief review of these technologies, as well as information about the ALD Locator app and website that can help your patients find them in their own communities.
Still, there are difficult listening situations that even the most advanced hearing aids struggle to overcome. Stadium events, classroom lectures, and church services, for example, all pose unique challenges for hearing aid users. Distance from the speaker, background noise, and poor acoustics can contribute to a frustrating and tiring listening experience that hearing aids cannot alleviate entirely.
Helping your patients set reasonable expectations of what hearing aids can and cannot accomplish goes a long way towards ensuring they are satisfied with their purchase. You can help by giving patients the knowledge they need to navigate the difficult listening situations they will inevitably encounter daily.
Assistive listening systems (ALS) can be a very effective companion technology to hearing aids. Educating hearing aid users on the role they play can be a key factor to long-term patient satisfaction in your practice.
Figure 1. How do Assistive Listening Systems (ALS) work? ALS are comprised of several devices working together.
Understanding ALS Technology
ALS systems work by eliminating background noise and increasing signal-to-noise ratio, thereby delivering clean crisp audio directly to the user (Figure 1). The Americans with Disabilities Act, or ADA, requires that all public venues which rely on amplified audio have an assistive listening system installed and that hearing-aid compatible receivers be readily available. There are four primary types of ALS technology patients may encounter. Helping patients understand how to utilize each technology to improve their hearing in different environments is crucial:
While most venues are required to provide assistive listening to their patrons, it can sometimes be difficult to determine which venues are compliant. Signage indicating the presence of ALS is required by law (Figure 2) and will indicate whether the venue has an induction loop or another type of technology. If a venue has a hearing loop installed, it will be indicated with assistive listening signage featuring the letter “T.”
Figure 2. Signage helps consumers with hearing impairment identify venues where ALS technology is available.

ALD Locator
Assistive listening is an amazing complement to hearing aid technology, but many users are not aware that their favorite venues may have a system installed. ALDLocator.com was created so that patrons can find venues that offer assistive listening (Figure 3). Users can search by location or search for their favorite venues by name to determine if an ALS system is available, and, if so, what type. Patrons can also post reviews of the ALS system, or request a compliant venue be added to the locator. Additionally, the ALD Locator has a convenient mobile app for iOS and Android, making it easier than ever to find assistive listening on the go.
