We all know somebody affected by hearing loss, as nearly 1 in 5 Australians live with the condition. Quality of life can be significantly compromised for people with hearing loss and their families.
In contradiction to many people's understanding, hearing loss is rarely similar to the effect of turning down the volume on a stereo. If you feel that your hearing is not what it used to be, or are concerned that a loved one may be experiencing hearing loss - take a couple of minutes to do the online hearing tests provided here. However, conductive loss accounts for only 10% of all hearing losses, and they range from mild to moderate in severity. When volume is sufficiently increased, clarity and understanding are usually intact for someone with a conductive hearing loss. Hearing loss that originates in the inner ear is referred to as sensorineural hearing loss or - in laymen's terms, nerve deafness. While the overall volume of sound may be reduced, the clarity of sounds or voices is also affected. An example of a mixed hearing loss may be someone with inner ear damage due to exposure to noise in their workplace over many years, who also currently has an infection that has led to a fluid build up in the middle ear.
While the ageing process is a major contributor to hearing loss, it is certainly not a condition reserved for the later stages of life.
Not surprisingly, given the impact of noise, males are considerably more likely to have hearing loss than women - including being twice as likely to have a moderate to severe hearing loss. This graph shown here illustrates the time it takes to cause permanent damage to your hearing when you're exposed to different levels of sound.

While digital TV, both broadcast and IP-delivered, offers great potential for interactivity and receiver functionality, it is all too easy to overlook the needs of those affected by sensory and physical disabilities. The World Health Organisation (WHO) states, in a 2013 Fact Sheet, that there are a billion people worldwide with some form of disability.
According to the European Disability Forum (EDF), One in four Europeans has a family member with a disability, suggesting that around 25% of households in Europe include someone with a disability. Using an audio-visual medium like digital television creates challenges for specific groups of disabled and older people. From early on, the DTG has recognised the needs of disabled television consumers and has been active in trying to harness opportunities to improve the accessibility of digital television. DTG and its members contributed significantly to the Government's Digital Action Plan, including in the work to ensure that accessible solutions were available to older and disabled people as switchover was taking place in the UK.
More recently, the DTG's focus has been on Connected TV and ensuring that access services such as subtitles and audio description are as widely available as possible. As television evolves, the DTG Accessibility Working Group continues to develop guidance, define opportunities to harness new technologies to improve services and products and raises awareness amongst key stakeholders about the need for accessible solutions and content. The DTG's ground-breaking work on Text-to-Speech for digital television (see Text to Speech tab above), through a partnership with DigitalEurope, culminated in an International Standard IEC 62731: Text-to-speech for television - General requirements.
In addition to ongoing work to keep the U-Book up to date, the Accessibility Working Group is now also preparing guidelines on the clarity of broadcast speech.
DTG U-Book: UK Digital TV Usability and Accessibility Guidelines, including Text to Speech, Version 3, December 2014. The DTG Receiver Recommendations publication gives details of the mandatory requirements for accessibility features in receivers. The older DTG Implementation Guidelines and Recommendations for Text-to-Speech have been updated and are now included in the U-Book. Hearing loss is often categorised on the basis of degree of loss, from mild, moderate to severe and profound.
A common problem for people with hearing loss is that people experience difficulty in discerning speech from background. Subtitles are essential for many people with hearing loss, while Sign Language interpretation opens up content for those for whom Sign Language is their first language. Despite common misconceptions, blind and partially sighted people do use television, just like other consumers. Like other conditions, colour blindness comes in varying degrees from mild over moderate to severe.
The term "physical disabilities" covers a quite wide ranging set of conditions and abilities. For this group, interface accessibility (usually via alternative input devices) tends to be a high priority. Sometimes the origins are genetic, in other cases the result of injury, trauma or as a consequence of diseases such as meningitis or brain tumours. Dyslexia is often included in the group of cognitive disabilities, being primarily a reading disability.
DTG U-Book: UK Digital TV Usability and Accessibility Guidelines, including Text to Speech,Version 3, December 2014. The DTG Accessibility Working Group maintains the U-Book, the UK Digital TV Usability and Accessibility Guidelines, including Text to Speech. Part A - Usability Guidelines: information on the best industry practices for ensuring a good, usable customer experience when using digital television products.
Part B - Accessibility Guidelines: offers guidelines to manufacturers wishing to incorporate accessibility features into their products. Part C - Connected TV Implementation Guidelines: these are currently under development by the Working Group and expected to be published later this year. The challenges that disabled and older people face when using television can be divided between interface accessibility barriers and impediments in using the television content itself.
Also, as more and more features are added to television products and services, some viewers find them more complicated to use. Connected TV also offers new prospects for improved accessibility beyond what could be done with traditional solutions. However, in addition to content accessibility, the television product itself, its User Interface (UI), also needs to be accessible to people with sight loss.
Such talking features provide a spoken alternative to the visual menus and other components of the default interface.
The Digital TV Group, working with organisations representing blind and partially-sighted users, has been a pioneer in this field.

Later, this excellent piece of work by DTG was adopted by DigitalEurope and taken to the International Electrotechnical Commission (IEC). As a result of this work, we have seen more and more solutions with integrated text-to-speech (talking features) being introduced to the UK market.
In order to make television content accessible to people with sensory disabilities and to older viewers, the UK has been a forerunner in the delivery of subtitling, signing or audio description.
Audio description and subtitles are closed services, which means the viewer can turn them on or off as they require. Subtitles are an elective service which, when turned on, provides a text representation of the dialogue or commentary. Another issue is the availability of subtitles on non-domestic TV receivers such as are found in many hotels and fed from an in-house distribution system.
Whilst subtitling is the obvious facility to assist the hard-of-hearing in accessing TV programmes, for many viewers with moderate hearing loss subtitles are intrusive in a family-viewing environment and unnecessary if the TV audio can be made available to them at a higher level than for normal viewing or in a processed form that emphasises the higher frequencies. The provision of facilities for enabling both the main and any secondary audio outputs simultaneously is strongly encouraged.
Audio Description is an additional narrative that describes the visual elements of a programme, such as the scene, actions, body language and expressions and is intended to make the programme clear through sound. Broadcast-mix: this comes as alternative audio including both the standard programme audio and the audio description track, brought together by the broadcaster.
Receiver-mix: this is where the audio description is an additional audio track that the receiver combines with the main audio. According to the 2011 Census, there are approximately 25,000 people who use British Sign Language (BSL) as their first language. Complaints from viewers about the difficulty of understanding dialogue ranks high on the list of calls to broadcasters. In 2010 BBC Vision carried out two separate surveys with its Pulse on-line panel of 20,000 viewers to identify the issues which caused problems with television sound.
Clarity of speech: poor and very fast delivery, mumbling and muffled dialogue, turning away from camera, people talking over each other, trailing off at the end of sentences. Unfamiliar or strong accents: Audiences find accents other than their own harder to understand. Background noise - locations with heavy traffic, babbling streams, farmyard animals, in fact any intrusive background noise can make it difficult to hear what's being said. Background music - particularly heavily percussive music or music with spikes that cut across dialogue.
A common problem for people with hearing loss is that they experience difficulty in discerning speech from background sounds. More than 10 million people in the UK have hearing loss—about one in six of the population. Age-related damage to the cochlea, or presbycusis, is the single biggest cause of hearing loss. Most of the 9 million deaf and hard of hearing people have developed a hearing loss as they get older. The curves below illustrate the way in which hearing loss increases with age, both basic sensitivity and frequency-dependent loss. A vital factor is that a majority of consonants, which are crucial to understanding, are centred in the higher frequency range, where hearing loss is most marked. While subtitles are a solution for some viewers, many of those suffering from mild hearing loss prefer not to use subtitles, particularly for news programmes, as the delay and errors can be distracting.
A study carried out by the BBC in 2003 revealed that the over-55s account for nearly 40% of peak-time audiences, and that the average time spent watching all channels was, at 4hrs 21mins, about 45 minutes longer for the 55 – 65 year-old than for the population as a whole.
Considering just the over-65s, 29% of programmes posed speech audibility problems to at least 10% of their viewers.
You can hear for yourself what it's like to have impaired hearing by using software simulators.
University College London's HearLoss - an interactive Windows PC program for demonstrating to normally hearing people the effects of hearing loss. University of Cambridge Inclusive Design Kit - demonstrates some of the main effects of common types of hearing loss in the UK.
Many of the difficulties affecting the clarity of speech can be reduced or removed by care taken in the production process, including pre-production planning and quality control. Whenever possible, prior to release a programme should be played through domestic quality loudspeakers to someone not involved in the post production so that any instances of unclear dialogue can be identified and rectified prior to transmission. The BBC's College of Production has made a number of useful training videos giving practical advice on, among many other things, acquiring, recording and post-producing sound for television. The extent of the hearing loss varies too, from a mild to a severe hearing loss where loud safety signals may not be heard. The good news is that conductive hearing loss can often be medically treated, and in many cases, hearing can be completely restored. Other symptoms may also be present, such as ear pain, drainage from the ears, or a feeling of pressure or a blockage. In more than 95% of cases involving sensorineural hearing loss, hearing aids or cochlear implants are the recommended course of treatment.
People with sensorineural hearing loss will often hear people speaking, but can't always understand all the words, even when the volume is adequate. Studies have shown that exposure to noise is thought to be a contributing factor in around 37% of cases of the condition - and interestingly, around 50% of Australians with hearing loss are still of traditional working age (i.e.
This is illustrated through mandatory provision of ear protection on work sites and within factories.
A sound that has high frequencies of vibration will excite receptor cells near the opening of the cochlea, while a sound mostly containing low frequencies will stimulate cells at the end of the cochlea. It also confirms that the incidence of disability is increasing due to population ageing, amongst other causes. Individuals with sight or hearing loss are particularly affected, but there are also accessibility challenges for people with physical and cognitive disabilities. DTG has also published the U-Book, which complements the DTG D-Book and provides detailed Usability and Accessibility Guidelines for manufacturers. The Working Group includes representatives of manufacturers, broadcasters, charities and organisations working for those with a wide range of disabilities, including sight and hearing loss. Nevertheless, for practical reasons it may be helpful to identify some of the key stakeholder groups for the DTG's accessibility and usability work. People who develop hearing loss later in life usually have acquired spoken language, whereas those born deaf or with severe hearing loss from birth (or shortly thereafter) often use British Sign Language (BSL).

Even the minor hearing loss that is a natural result of ageing leads to a noticeable reduction in the ability to follow dialogue over background sound. In fact, many people with sight loss have some perception and most, of course, are able to enjoy the sound. In most cases colour blindness is genetically inherited, while diseases such as diabetes and medication are other common causes. Nevertheless, colour blindness can occur for the whole colour spectrum and even black can be confused for dark green or dark blue in some cases. This user group includes people with motor impairments, dexterity barriers as well as wheelchair users and individuals with missing or differently formed limbs.
Indeed, there exist many types of cognitive disabilities covering a wide range of difficulties and deficits involving language understanding, reading, memory, visual comprehension, problem solving, reasoning and reduced mathematical comprehension. Sight and hearing loss, reduced dexterity and sometimes decreased cognitive faculties are all typical corollaries of getting older. This part includes guidance on remote controls, Electronic Programme Guides, User Interfaces, labelling, user documentation, etc. In addition, the DTG Receiver Recommendations give details of the mandatory requirements for accessibility features in receivers.
The advent of Connected TV brings many benefits to viewers, bringing together traditional television services with Internet based content.
However, the added functionality and jargon of Connected TV can create new challenges for accessibility and usability. The U-Book's Connected TV section identifies these opportunities to harness Connected TV as a means to bring innovation to accessibility-related features and content. Where content is concerned, the DTG and the UK have been pioneers in the provision of audio description, a major feature to give this user group an equivalent experience in consuming television programmes. A talking interface can provide a substantial improvement in accessibility and usability for this group of consumers. By using text-to-speech in a television solution, a person operating the product via the spoken interface will receive the same feedback and be able to perform the same tasks as someone using the default (visual) interface.
It started work on text-to-speech in 2007, bringing together industry and other stakeholders to write a technical specification for Text to Speech (this has since been included in the U-Book). The U-Book contains best practice guidance surrounding the implementation of access services in digital television solutions. They are normally shown at the bottom of the picture and benefit from the use of different-coloured characters for different speakers, when applicable. Whilst many receivers have an option for the audio to be processed to give an output that is more intelligible for the hard-of-hearing, this is suitable only for solitary viewing. Audio Description is used primarily by blind and partially sighted people and supplements the dialogue spoken by the cast. When activating broadcast-mix audio description, the receiver selects this alternative instead of the default audio. The research showed that nearly 60% of viewers had some trouble hearing what was said in TV programmes. This includes over six million people who could benefit from hearing aids (hearing loss of at least 35dB in the better ear). With HearLoss you can replay speech, music and noise under a variety of loudness, filtering and masking conditions typical of hearing impairments. Use of a hearing-loss simulator provides a convenient way of checking the clarity of the speech element of a programme and is encouraged.
More commonly it is manifested as a difficulty with word understanding, particularly in the presence of background noise. This can lead to conversations being difficult to follow - particularly in noisy environments where competing background noise 'scrambles' speech and conversations. Nevertheless, every day millions of Australians are exposing themselves to noise levels that will surely lead to long-term damage to their hearing, including the use of personal stereo systems.
Commonly, over time the high frequency hair cell receptors receive more movement by the incoming pressure waves of the fluid inside the cochlea - so are more prone to long term damage than the low frequency hair cell receptors, which are more protected further up the cochlea.
Being able to use television programmes is not just nice to have, but indeed a key part of citizenship and participation. BSL was recognised by the Government as a language in its own right in March 2003 Using the 2011 Census there are approximately 25,000 people in the UK aged three and over who use sign language as their main language. The DTG Accessibility Working Group is currently involved in a clean audio project to improve the audibility of speech in television programmes.
Nevertheless, blind people and those with significant sight loss are arguably the group that faces the biggest accessibility challenges.
The use of specialised keyboards, large button remotes, single switch devices and voice control are amongst the tools used by this group. While the degree of disability in older people is generally milder compared to other groups of disabled people, it is compounded by the fact that several of these conditions, both physical and sensory, tend to co-exist amongst these consumers rather than a single disability dominating the individual's profile of abilities and preferences. Subtitles are the most used access service in the UK, with millions of viewers enjoying them. Not unsurprisingly, being able to follow conversations is the single biggest reason that people seek our help.
Yet, despite the prevalence of hearing loss, it is also an often overlooked group and one that is very diverse in terms of its make-up and requirements.
It is a visual language, with its own grammar and principles, which are completely different from the grammatical structure of English.
They face significant barriers both in terms of using television products (interface accessibility) as well as with regard to content (where Audio Description is a key service for this group).
Prototype systems demonstrating closed signing have been developed, but there are many technical and economic barriers to their real-world deployment. Amongst the main user groups for subtitles are those with hearing loss, older people and those for whom English is not their first language.
To provide BSL interpretation for a television programme, a sign language interpreter is shown in-vision.
