Here we have a very high pitched cat and dog whistle noise which shrieks for 12 hours. Also doubles as a great kid irritation device. As people age they often can't hear very high pitched sounds anymore, but kids can usually hear them distinctly. This one sounds a lot like tinnitus to me and I find that it gives me a headache if I play it too loudly for too long.
