hearing tests - where and how?

You can borrow mine, along with a calibrator and SPL meter, IF you promise to send it back to me within a month or so.

Also, research has proven that the brain can indeed perceive frequencies above those that the ear can hear, which is fascinating.

Actually, only one lab has promoted that and none of their findings have been replicated by any other lab.

Kal, not sure where you got that - the subject has been researched for decades by many different people in many different countries, along with much other brain research. A Google search should yield more info than anyone would ever really care to know on the subject. Much of the knowledge was discovered quite accidentally when researchers were studying the brains of people who were deaf. There is also alot of fascinating research out there about how the brain perceives spatial distances/relationships, much of which is actually received through the ear rather than the eye, again even in deaf people. I came across some of it while researching a paper I had to write back in my college days for an acoustics course. Don't have any of those notes anymore, that was over twenty years ago now, but I know the info is out there.

From many years as a neuroscientist who studies and lectures on the topic. When there is reliable, confirmed and replicated evidence, let me know.
