Difficult to write a wiki article. the musicchart1.pdf is a useful guide but there are quite a few factual errors, with ranges of instruments and with some of the frequencies. For example: Tuba and string bass have the same low note "C". Kick drum attack is usually somewhere between 1-3kHz. Plus some more subjective errors: The high freq band usually goes to 12kHz and then the very highs. I've always associated ultra-high freq with freqs above 22kHz.
The problem is, all of us in the industry have slightly different descriptions and boundaries so it's very difficult to write a definitive article.
