Overview Assistive Listening:

This 4-Person Assistive Listening System with Neckloops and ADA Plaque is a multichannel solution (in the 72-76 MHz band) to meet the needs of the Americans with Disabilities Act (ADA) standards for accessible design, useful for venues up to 100 seats. In addition to ensuring that public facilities are compliant; the system can also be used to improve comprehension by people who have difficulty hearing or understanding speech in various settings including meeting rooms, houses of worship, movie theatres, schools, public hearing rooms, and more. The audio is sent wirelessly straight to their ears, avoiding the degrading effects of noise and distance on speech intelligibility. This system can be expanded with as many R-120 Receivers and Neckloops as required.

Assistive Listening System includes:

  • (4)  Enersound R-120 Digital FM Receivers with LCD screen (no backlight)
  • (4)  Enersound Double Earphones for Audience
  • (1) Enersound T-500 17-Channel Base Transmitter
  • (2) Telecoil Neckloops
  • (1) ADA Plaque 
  • (1) ANT-500 Antenna

Assistive listening systems

Assistive listening systems are small personal devices designed to help people with hearing disabilities to improve their hearing skills. 

To put it in simple words, they are small amplifiers that help you bring the sounds closer to your ears. There are different types of assistive listening devices, either for one-on-one conversations or for public places and event venues.

These can be used for people with different degrees of hearing loss.

Assistive listening devices are small personal devices, which help improve listening and communication for people with different degrees of hearing loss (whether they use a hearing aid or not).

They are small handheld devices, which bring the sound you want to hear closer to your ears. They are not a replacement for hearing aids, but they can be helpful in specific listening situations.

These can be used to improve one-on-one communication and also to improve hearing in public places such as government buildings, houses of worship, cinemas, auditoriums, theaters and more.

Assistive listening devices separate the sounds, isolating the ambient noise and only bringing the speech directly into the ear. This capacity is known as ‘Speech to noise ratio’.

Hearing aids can have certain limitations in some environments, so assistive listening systems can help improve their range and effectiveness.

Differences between Assistive Listening Systems and Hearing Aids.

If you suffer from any degree of hearing loss, you may already know that Assistive Listening Systems and Hearing Aids are two different things.

Both kinds of devices are used on the ears, and they serve the function of amplifying sounds. Even though they are similar technologies, it is important to understand the differences between them.

Hearing aids are small devices that are specially programmed and fitted to your ears and according to your degree and type of hearing loss. They are specifically designed to amplify the different sounds you want to hear, and not just only amplify volume in general.

Assistive listening devices are especially useful in environments where there is a lot of ambient noise or where the source of sound is at a considerable distance from the person (places such as convention centers, theater rooms, movie theaters, churches, banquet halls, etc.) and be used for people with hearing aids or not. 

Thanks to Assistive Listening Systems, people with hearing loss can listen to the sounds being transmitted through a sound system, with the help of a small device called a receiver that can be connected to earphones or to neck loops for people using hearing aids with telecoil. 

There are different types of Assistive Listening Devices available on the market:

  • FM (Frequency modulation) is a wireless transmission method that uses radio broadcast technology to deliver sounds. This is the most common type of an Assistive Listening System. It consists of two main components: A radio transmitter and a wireless receiver. The transmitter is responsible for capturing the sound coming from a microphone or sound system, and then sending it to the receiver.The receivers may have more or less functions, depending on how they were designed, and they also offer different ways to deliver the sound, through earphones (for people who don’t have hearing aids) or a neck loop (which eliminates the need for headphones in case you already use a hearing aid with t-coil)
  • Infrared Systems use infrared light waves to transmit the sound from the sound system to an Infrared receiver. These light waves cannot pass through walls and are affected by sunlight, which is something to consider. IR systems tend to be more expensive than FM systems and the set-up is more complex as it requires additional equipment and is usually done by an experienced technician. The main components of an IR System are a modulatorthat receives audio signals from the Public Address or sound system, an emitter that transmits the audio signal to the receivers of the hard of hearing, receivers with headphones or neck-loops, and sometimes a transmitter forsmaller rooms or portable applications that combine a modulator and emitter into one device.

Are assistive listening systems mandatory in public places?

Since 2010, new standards for the Americans With Disabilities Act (ADA) became law. The ADA requires that title II entities (State and local governments) and title III entities (businesses and nonprofit organizations that serve the public) communicate effectively with people who have communication disabilities. The goal is to ensure that communication with people with vision, hearing, or speech disabilities is equally effective as communication with people without disabilities. To comply with ADA regulations, in each assembly area where audible communication is integral to the use of the space, an assistive listening system shall be provided.

    A must have

    Posted by Molly on 3rd Nov 2020

    Among our church s plans was to purchase a listening assistance system. A fellow minister recommended this as they use it in their church. It was easy to attach to our sound system and it works perfectly.

    A great addition to our auditorium

    Posted by Victor on 11th Jul 2020

    After some reforms in our auditorium, we realized that something was still missing: Compliance with the law and provision of hearing assistance. For our room size, this system seemed the best option.

    We were in need of an assistive listening system and this one seemed ideal to us. We love the fact that we can expand it in the future. The neckloops are a plus for our hearing impaired who use hearing aids.
