What is Assistive Technology?

Assistive technology is the term used to describe a wide range of devices, tools, software, and equipment specifically designed to aid and enhance the daily lives of individuals with disabilities. It encompasses a vast array of solutions. However, its fundamental purpose remains consistent: to break down barriers and enable those with disabilities to engage more fully in society.

By harnessing the power of assistive technology, organizations can empower their entire target audience to overcome the challenges they face, and, in doing so, enhance their independence, autonomy, and quality of life.

How Assistive Technology Benefits Deaf and Hard of Hearing Individuals

Many people often ask themselves, who needs Assistive Technologies? The truth is it benefits a wide variety of individuals. However, for those who experience deafness and hearing impairments, it is beneficial as it removes barriers and improves the overall quality of life in everyday settings – whether at home, at work, in a learning environment, or social interactions.

However, it’s essential to recognise that assistive technology isn’t about addressing a disability. It’s about bridging communication gaps to make individuals feel more connected in previously challenging situations. The aging population is one group that can really benefit from Assistive Technology for hearing. You can learn more about the benefits of assistive technology for old people here.

Types of Assistive Devices for Hearing Impairments

Assistive devices come in various forms, each one catering to the unique needs of individual users. Here are a few examples of the most common types and some real-world scenarios to illustrate their importance.

Assistive Listening Devices

Assistive listening devices (ALDs) help individuals hear more clearly in specific situations by amplifying sounds and reducing background noise. Most helpful in filtering out noise so people can focus on one-on-one conversations, ALDs are typically hand-held amplifiers with inbuilt microphones.

ALDs in Action

Meet Mary, a grandparent with age-related hearing loss. She often attends parent/teacher evenings on behalf of her daughter, who works shifts. Her ALD helps her to focus on the dialogue of each tutor over all the other chatter in the busy school hall.

Augmentative and Alternative Communication Devices

Augmentative and alternative communication (AAC) devices provide alternative means of communication for individuals who can’t rely on spoken language due to severe hearing loss or speech impairments. Often used interchangeably with the term speech-generating device (SGD), AACs usually come in the form of a tablet or laptop. You can learn more about assistive technology for communication here.

AACs in Action

David was born with profound hearing loss. He uses an AAC device with symbols and text-to-speech software to communicate with his family and teachers. Complete with a grid of symbols representing words and phrases to vocalize his messages, the software allows him to effectively express his thoughts, needs, and feelings.

Alerting Devices

Alerting devices provide hearing impaired individuals with visual or tactile cues to enhance safety and awareness when important sounds occur or alarms go off. Also known as signalers or notification devices, they typically use flashing lights and/or vibrations to alert people to various environmental sounds.

Specific Examples of Assistive Technology Solutions for Hearing Impairments

Assistive technology solutions continue to evolve with advances in technology, providing evermore options and improved functionality for individuals with hearing impairments. Here is a list of some of the most commonly used technologies.

Audio Induction/Hearing Loop

Commonly used in public spaces like theatres, churches, and transportation terminals, etc., audio induction/hearing loops utilise electromagnetic fields to transmit sound directly to users’ hearing aids or cochlear implants, providing clear audio with reduced background noise.

Frequency Modulation (FM) Systems

Often used in educational settings, FM systems are wireless devices that can be used with both hearing aids and cochlear implants. They consist of a transmitter and receiver that amplify and transmit sound, allowing teachers to communicate directly into students’ receivers.

Infrared Listening Systems

A popular alternative to an induction/hearing loop system, infrared listening devices are commonly used in theatres, auditoriums, and conference rooms, etc. As the name suggests, they transmit audio signals via infrared light to provide clear audio quality without radio interference.

Personal Sound Amplifier Systems

Personal sound amplifier systems (PSAPs) are portable devices that amplify sound for personal use. Comprised of a microphone, receiver and amplifier, they can be used with headphones or earbuds, and typically come with adjustable settings to allow for customisable amplification based on individual needs.

Bluetooth Systems

Bluetooth connectivity enables wireless streaming of audio content directly to individual hearing devices. Bluetooth technology can be used with either hearing aids or cochlear implants. It allows connectivity to various audio sources and can be used to facilitate hands-free calling and audio control through smartphones.

One-to-One Communicators

These are personal communication devices that help with one-on-one conversations. They filter out environmental noise interference, so it’s easier to talk to someone without shouting. The technology requires active use by both parties in the conversation, with the speaker using a microphone that relays what they say into a receiver in the wearer’s hearing aid or a headset.

Text-Based Services

In today’s digital world, text-based services have become increasingly relevant – primarily due to the proliferation of video content. They provide an alternative means of experiencing audio and video, offering both convenience and inclusivity.

Text-to-Speech Technology

Text-to-speech (TTS) technology converts written text into spoken language. This process involves four key steps:

  • Input – Users input written content from a webpage, document, or message.
  • Analysis – The TTS system analyzes the text, identifying words, sentences, and punctuation.
  • Synthesis – The system generates a synthetic human voice using natural language processing and machine learning techniques.
  • Output – The synthesized speech is delivered through speakers or headphones for the user to hear.

TTS technology has come a long way in recent years, offering high-quality voices and customisation options for pitch, speed, and even accents. It can be employed in various scenarios, from web browsing and reading documents to receiving SMS messages and interacting with digital assistants. 

Text-to-speech is beneficial to a range of different disabilities, not just people with low hearing. See how this Assistive technology benefits people with Autism here.

Audio/Video Transcriptions

Transcriptions are an essential component of assistive technology, offering access to multimedia content and information that may have been previously challenging to comprehend. More than 80% of online traffic is in video format, making accurate transcription vital for those with hearing impairments. But transcription isn’t just for those with hearing difficulties. It also helps anyone to access content in noisy environments where it’s difficult to hear the audio.

How Businesses Can Assist Individuals with Hearing Impairments

There are several steps that businesses could – and should – be taking to make online content accessible to individuals with hearing impairments. Here is a list of best practices to follow:

  • Optimise website design and user interface by ensuring straightforward and consistent navigation across all pages. This benefits all website visitors, not just those with hearing problems.
