The human ear can usually hear from 20Hz to 20,000Hz. If you cannot hear above 5,000 Hz, then you probably have severe hearing loss. _http://www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/_ (http://www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/) I have only halfway decent speakers - so I probably can't output the higher frequencies. I made it to 12kHz only. It must be all that time near large computer equipment, or my speakers. -William In a message dated 11/11/2010 10:48:20 A.M. Eastern Standard Time, [email protected] writes:
Hello Hans Illich, good calculation, but A-5000 corresponds to a 4-times smaller E-flat 0,44% sharp, if we take A=440 as the base. Based upon A=440: E-flat=311,13 the corresponding fraction of 5000 be 312,50 which is 0,44% sharp. This E-flat near 5000 Hz would be 22Hz sharp and be in the 5th octave = E-flat´´´´´ thus exceeding most peoples hearing capabilities. Or explained musically: two octaves higher than the notated high E-flat, written with 3 ledger lines above staff in concert notation (=sound as written). It might be notated as trebble clef plus "octava 2" above or similar. It would also mean, that A-5000 does not exist, if we go after human naming of pitches. Mei liawa ! Oba bist guad im kalkulian.
