What Does SDH Subtitles Mean?
Put simply, SDH subtitles are Subtitles for the Deaf and Hard -of -Hearing.
You probably already know that subtitles are the process of displaying textual forms of aural content in videos. However, SDH subtitles are a type of subtitles specifically designed for those who cannot or have trouble hearing the audio of a piece of content.
The text typically runs along the bottom of the video screen. SDH subtitles will always display dialog, usually indicating the different speakers’ names, as well as describing any other aural content or sounds.
What is the Difference Between SDH Subtitles and Closed Captions?
CC, or Closed Captions, are subtitles that can be turned on and off. They tend to be offered in multiple languages, and usually only translate the dialog.
The difference between SDH subtitles and Closed Captions is that while Closed Captions assume viewers can hear audio and sounds, SDH subtitles are designed for viewers who cannot.
Need an example? Just imagine the iconic 1975 film Jaws.
While Closed Captions might only display the dialogue of someone shouting “SHARK!”, SDH subtitles are likely to include crucial sounds and aural details that are important to the plot like, “[Foreboding violin theme playing]” or “[Children screaming]”
I think we can all agree that the sinister Jaws theme music is one of the most memorable parts of the film, meaning it is even more important to describe it for those who cannot hear it.
Why are SDH Subtitles Used?
Now we have tackled “What does SDH subtitles mean?”, let us discuss their usage. SDH subtitles are important because everyone should be able to consume, fully understand and enjoy video content.
Worldwide, an estimated 466 million people, 5% of the population, have disabling hearing loss, and this number is expected to rise to 900 million by 2050.
Therefore, whether you are disseminating an informational video, a video-led advert for a small business on social media or an indie film due to be launched in cinemas, deaf and hard-of-hearing viewers are sure to make up a significant portion of your potential audience.
Not only are SDH subtitles important for ensuring that vital public information gets widely disseminated, but they also ensure that those who are deaf and hard-of-hearing can equally learn from the training course, fully understand the meeting discussion, or enjoy entertainment content.
These days, SDH subtitles are ever-more crucial for ensuring your content is accessible, inclusive, and wide-reaching.
What Does The Law Say About SDH Subtitles?
Not only is it good practice to ensure that you provide SDH subtitles for your content, but in some cases, they could be necessary to comply with the law.
With eLearning training courses and remote video conferences becoming the new norm of the business world and an increasingly diverse workforce due to globalization, more countries are passing laws and acts to ensure the accessibility of various content, and SDH is usually a must under these regulatory requirements.
It is important to find out whether you need to provide SDH subtitles in order to comply with this legislation. If you are not sure, it is safest and more inclusive to provide them anyway. Or you can always get in touch with us for advice.
