What Technology Can be Used by People with a Hearing Disability to Listen to a Narration?

People living with hearing impairment can utilize various technologies that help enhance sound quality and speech comprehension, including assistive listening devices, captioning devices and alerting devices.

There are various devices designed to amplify sounds in noisy environments. These can work with hearing aids or cochlear implants or directly with an induction loop system that comes equipped with certain hearing aids. In this article, we will discuss this question: What Technology Can be Used by People with a Hearing Disability to Listen to a Narration?

Assistive Listening Devices (ALDs)

Assistive listening devices (ALDs) amplify sound to enhance speech intelligibility and reduce background noise, providing people with hearing loss an effective means of communicating with family, friends and coworkers as well as enjoying recreational activities like television and radio at home or in their communities.

ALDs can be used alone or with other technologies, like hearing aids, to enhance signal to noise ratio and enhance intelligibility of sounds. They’re particularly helpful for situations in which sounds fade as you move further from their source and in environments with poor acoustics or echo-distorted environments that distort audio output.

Example ALDs include sound field systems, loop systems, FM systems and infrared systems. All of these technologies use a similar principle: microphones capture audio signals and convert them to electrical energy before amplifying and transmitting it to receivers worn by those with hearing loss – such as headphones or neck loops that produce electromagnetic waves picked up by hearing aid telecoils, or directly connected as audio input to hearing aids.

These assistive listening devices, also referred to as “small group” assistive listening devices, are particularly useful in conference rooms, lecture halls, and other public places where large crowds make hearing presentations or songs difficult. Such systems may even be required under laws like the Americans with Disabilities Act in other countries.

As well as aiding with listening, many ALDs are designed to alert an individual with hearing loss to environmental sounds. Alarm clocks, doorbell sensors, baby alarms and smoke detectors may feature flashing lights or vibrators that signal potential danger.

Some ALDs enable people with vision impairments or no voice to communicate by text, which can be displayed live for those needing real time reading of text messages from friends and family members. Researchers are working on developing portable devices which will enable those with different degrees of speech loss to type messages into it that will then be converted to their personal synthetic voice and read aloud out loud.

Sound Field Systems

Sound field systems differ from personal amplification systems in that listeners don’t require receivers; instead, speakers’ voices are amplified and transmitted through loudspeakers in the room so students can hear clearly no matter where they sit in class. This enables speakers to speak more comfortably at an ordinary conversational volume level while students remain able to listen easily wherever they sit within the classroom.

Soundfield systems go far beyond simply increasing speech clarity for teachers; research indicates they can help students who struggle in classroom environments due to auditory processing deficits or attention deficits, improving classroom acoustics and lowering noise levels that disrupt learning.

Teachers can ease the strain of constantly shouting or speaking at unnaturally high volumes, which often results in illness, fatigue and absence from teaching. By using a soundfield system instead, teachers can still get every student’s attention without raising their voice, while simultaneously improving health and wellbeing by decreasing vocal strain.

As with other assistive listening devices, soundfield systems should always be utilized under the supervision of an Educational Audiologist or Visiting Teacher of the Deaf. They will advise schools as to the acoustic accommodations required for individual students as well as helping to identify those with PWCDs who could potentially benefit from using such systems.

At first, it’s essential to establish whether or not a student has a PWCD or cochlear implant. If this is true, then using a soundfield system alongside their PWCDs is recommended so as to ensure audio from microphones is received directly by them. Many soundfield systems now feature wirelessly connect to Roger hearing aids or cochlear implants and can automatically optimize for each individual student.

Amplified Phones

Amplified phones can make phone conversations more comfortable and easier to comprehend for those with hearing loss, who find it challenging to hear callers on the line. These devices enable those with disabilities to amplify incoming call sound amplitude; additionally, these may also be utilized by those wearing professionally fitted hearing aids or cochlear implants.

As well as offering amplified sound, certain models feature additional features that make them easier to use for those with visual impairments as well. For example, some produce louder ringtones to help those with hearing loss recognize an incoming call more quickly, and may feature flashing “incoming call” lights to inform even severely impaired individuals when it is time to pick up the receiver.

New models of amplified phones have advanced far beyond the simple silver-dollar sized buttons that were once ubiquitous, offering modern features like caller ID, digital answering machines and expandable handsets. Many are even available through state assistive technology programs that provide free or discounted access for those qualifying.

One of the key advances to amplified phones has been intelligent amplification technology. This feature recognizes and filters out other sounds not associated with voice calls to ensure only speech signals are being amplified without distorting syllables of spoken text.

These technological innovations have revolutionized telehealth video meetings by making amplified phones an essential element. Amplified phones enable people with hearing disabilities to participate in medical appointments that require them to answer questions and follow medical directions, including answering calls directly connected to hearing aids or cochlear implants allowing enhanced audio while the video streamed, giving a clearer picture.

Telecommunications innovations have provided millions of people living with hearing loss with enhanced communication and quality-of-life enhancements, decreasing social isolation and helping those with hearing disability to lead more independent lives. Though these products cannot replace comprehensive hearing solutions such as hearing aids or cochlear implants, their growing demand has spurred industry innovation for accessible telecommunications by creating more innovative and affordable amplifying and amplifying-related devices.

Closed Captioning

Closed captioning and subtitles provide text-based descriptions of audio content for viewers who are blind or hearing impaired. Typically displayed at the bottom of videos synchronized to their audio track, closed captions provide descriptions such as dialogue, narration, sound effects and speaker identification that can be turned on or off according to viewer preference; closed captions can also help those learning a new language quickly or watching in noisy environments with lower volume settings.

Closed captioning provides accessibility for those with hearing disabilities while simultaneously improving comprehension and retention. Captions serve as an essential learning aid both inside the classroom and when watching movies at the cinema; studies demonstrate how those using captions experience improved academic and personal success both at home and at school. Captions also serve to help students understand context of films or television shows more quickly as well as serve as useful cues when writing essays or taking notes.

CART (Communication Access Real-time Translation) works similarly to captioning; however, instead of being displayed directly on a television or laptop screen, CART streams in real-time onto an accessible website for real-time display. Businesses and airports commonly employ this system in order to ensure accessibility for customers with hearing or vision impairment.

Closed captions differ from subtitles in that they’re designed specifically to meet the needs of deaf and hard-of-hearing viewers and should include all information found within an audio track, including music lyrics, sound effects and speaker identification. Subtitles typically only serve to communicate spoken content of films or videos.

According to a recent study, students who use captioning reported it as moderately or extremely helpful. When this data was divided by whether students reported having disabilities and those without, the results were quite similar: 95.6 percent of disabled students rated closed captioning helpful while 98.8 percent indicated it as such when polled separately from those without.
