I must be in the internet equivalent of the Bermuda triangle - I've tried the link in IE9, Opera, Firefox and Chrome, and although it takes me to the correct site, I get 'Page no longer exists' messages in all four browsers.
Tried the test, and it was normal for my age (56). For curiosity, I did the test a second time and put age 40 in, and it was still normal. I have an annual hearing test at work but the test is different because it emits bleeps at varying volumes and frequencies, and that is normal.
Despite all this, my wife still insists I’m going deaf.
