But I do also think the fact that the impact of deafness doesn’t just manifest itself in communication is ever really that well understood. It’s about the energy involved in lipreading and being attentive all day long.

Processing and constructing meaning out of half-heard words and sentences. Making guesses and figuring out context. And then thinking of something intelligent to say in response to an invariably random question.

It’s like doing jigsaws, Suduku and Scrabble all at the same time.

For deaf children and young people, especially, I don’t think this impact is as widely recognised as it should be. Advice to teachers on working with deaf children tends to talk far more about language and communication, rather than concentration fatigue.

And some deaf children and young people I meet haven’t been given the space to talk about what impact deafness has on them and to work out strategies to deal with it; like taking regular breaks and being honest to grown ups that they’re tired, without fear they’ll be labelled as lazy.
