Through a hearing aid, even the most expensive digital types, the sounds you hear are not as natural as when you were younger. This is one of several adjustments you will have to make. But they are very useful and many people feel more confident wearing a hearing than not.
Sign Language – it is important to be aware that, compared to English, British Sign Language (BSL) is a language in its own right and like most languages can take years to gain fluency.
An older person who acquires DSI because of ageing is unlikely to benefit from learning BSL unless they know someone else who uses that language.
Eyesight is an important factor in visual languages like BSL. But it is also a highly important part of communication for most older people. Visual clues such as facial expressions, body language and lip reading all play an important role in communication, increasingly so if both your sight and hearing deteriorate.
