I am always interested in what (volume) level is when an adult says that there hearing extends to 20khz. Is it the same level that would be considered a normal level for say the human voice. Most hearing tests done by audiologist test only to that level and range. If you use the same level for test tones that is not extremely loud at say 1khz and can hear a test tone at 20khz, that is impressive and dare I say it, quite unusual.
