The warning notice is intended for autistic people. Whilst some people on the Spectrum may be intolerant of loud noises, there is no reason why it should be a surprise unless the particular person has never seen and used a hand drier before.

If the individual also has a learning disorder, he or she may not be able to read the notice.

I still think it's bonkers. It has nothing to do with electrical safety. There are loud noises etc everywhere that some people have to get used to. If they were that badly affected i doubt they would be unsupervised the first time they go in to a public toilet. ( Before anyone accuses me of being uncaring i have an autistic son so have first hand experience of some of the problems he encounters )
