This was "stolen" from International Audio Review Hotline #16. I'm sure that it was reprinted in other issues also, but which ones i'm unsure of. While there is obviously no "exact standards" for various terminologies, some may find this interesting. While I myself would break things up differently, this is what IAR used for their reviews:
Lower Bass: 0.1 - 50 Hz
Upper Bass: 50 - 100 Hz
Warmth: 100 - 300 Hz
Lower Midrange 300 - 1000 Hz
Midrange 1000 - 3000 Hz
Upper Midrange 3000 - 7000 Hz
Lower Treble 7000 - 12,000 Hz
Mid Treble 12,000 - 17,000 Hz
Upper Treble 17,000 - 100,000 Hz
Hope this helps and explains some things to you. Sean
