ALS Assisted Listening Devices


Assisted listening devices provide targeted amplification to help people overcome issues related to high ambient noise levels, distance from sound sources, room acoustics, and room acoustic problems. They may be used independently or with hearing aids or cochlear implants for maximum benefit. Sort out the best hidden listening devices.

Various kinds of assistive listening systems include induction loop systems (also called hearing loop assistive listening), FM, and infrared systems. These devices can be found in classrooms, auditoriums, houses of worship, and places offering tours, such as museums.

What is ALS?

ALS is a progressive condition that gradually causes you to lose control of your muscles. Initial symptoms may include leg or arm weakness or stiffness; muscle twitching known as fasciculations; speech and swallowing become slurred, and you may need assistance turning a key or buttoning a shirt; eventually, all muscles become immovable, and you need daily help for eating, bathing and moving around; you may require ventilator use overnight while sleeping;

There is no cure for ALS, but there are ways to manage its symptoms and enhance quality of life. Your doctor can identify ALS by conducting a physical exam, taking a history of your health issues, conducting neurological exams to check for muscle weakness and twitching as well as an electromyogram (EMG), nerve conduction study, magnetic resonance imaging (MRI), spinal fluid test to measure different substances present within spinal cord fluid, or performing muscle biopsies under local anesthesia; small samples will then be sent for testing at laboratories across America or elsewhere in Canada.

Research to develop new treatments for ALS is underway, and you can participate in a clinical trial to gain more information and potentially test promising new therapies. We need volunteers from all ages, genders, races, and ethnicities so researchers can find better ways to detect, treat, or prevent diseases.

Lower your risk of ALS by refraining from smoking and limiting exposure to lead, pesticides, and other environmental toxins. Dieting well-balanced meals with regular physical exercise will also help. In addition, creating advance care directives with your healthcare wishes clearly stated can help avoid confusion or being given treatment you don’t want. It is also wise to receive regular mental health care.

ALS Transmitter

The ALS transmitter is at the core of any ALS system. It may connect directly to an existing PA system or operate independently as an FM (frequency modulation) transmitter, depending on its installation type. In either case, all audio channeled into PA systems–from microphone outputs through to music or sound effects–is broadcast to an ALS transmitter and then amplified using infrared emitters before being distributed through receivers situated around a room and featuring various listening attachments such as headphones, neck loops, single/double earbuds as well as direct audio input.

Audio enhancement solutions are beneficial in environments where hearing difficulties may be most impactful: concerts, public speaking events, council meetings, and movie theaters, to name just a few. Many venues must comply with the Americans with Disabilities Act by providing access to ALS services for attendees; still, traditional sound systems don’t always provide enough amplification to enable attendees to understand what’s being said or seen.

ALS transmitters offer an outstanding signal-to-noise ratio, essential in overcoming common hearing obstacles like distance from the sound source, ambient noise levels, and poor room acoustics. Their design may also limit interference from external sources like speakers or music equipment nearby.

In addition to offering superior SNR, ALS transmitters also help reduce distortion and reverberation within a space, making them especially helpful for people suffering from central auditory processing disorder, which affects speech perception and ability.

As more of the global population experiences hearing loss, venues and event planners must provide accessible assistive listening systems compliant with current standards. Partnering with an ALS provider ensures your guests who struggle to attend can still experience your event without needing complex technology or distracting headsets.

ALS Receiver

ALS devices differ from PA systems or Hearing Aids in that they do not amplify sound; instead, they concentrate on picking up specific sources of sound and transmitting it directly into listeners’ ears, which significantly improves signal clarity while eliminating issues like high ambient noise levels and echo that may impede speech intelligibility.

Hardwired or wireless ALS systems may be utilized. Hardwired models rely on connecting a microphone to a transmitter that sends infrared (IR) or radio waves for transmission. The signal reaches its intended receiver (telecoil compatible hearing aid or cochlear implant receiver), who then has control of their volume control for optimal hearing and clarity.

Infrared signals do not penetrate solid objects like walls and tables, meaning an infrared ALS requires a direct line of sight between its transmitter and receivers – something which may limit usage at venues where users cannot sit next to one another. However, Radio waves permeate solid objects, and FM ALSs can be utilized over more expansive areas than their IR counterparts.

An ALS that utilizes an induction loop, which may be hardwired or wireless, works much like an IR system but offers greater flexibility. The ALS transmitter connects directly with sound sources through a directional antenna and broadcasts signal over predetermined frequencies; people equipped with hearing aids compatible with this type of antenna can hear this signal simply by seating themselves within its coverage area.

In the study described above, 92 ALS patients were introduced to AAC devices (writing, communication boards, and switch control) over three-time points: at the start of rehabilitation, as each device was introduced, and finally, as repair ended. Upper motor and bulbar sub-scores improved significantly with each new AAC device being introduced; however, there were no statistical differences among writing, communication board, and eye control devices.

ALS Accessories

Before making any equipment purchases, meet with the team at your ALS clinic and discuss your needs with them first. They can make recommendations, connect you to resources, and guide you toward the most suitable solutions. Once it’s time to order new ALS equipment, the physical or occupational therapist who helped coordinate its purchase will visit your home and train on its use – AED Superstore provides various ALS accessories, including monitor and defibrillator consumables from ZOLL Medical Corporation as well as Philips Heartstart MRx ALS accessories from Philips Heartstart MRx from ZOLL Medical Corporation as well as Philips Heartstart MRx accessories from ZOLL Medical Corporation as well as Philips Heartstart MRx accessories from Philips Heartstart MRx, which are all available here – AED Superstore also provides many other manufacturers for purchase – when ordering.
