Subject: High frequency hearing From: David Robinson <david(at)ROBINSON.ORG> Date: Tue, 5 Nov 2002 06:28:13 -0800
I am trying to discover the limits of high frequency hearing in the most sensitive human listeners. The standard MAF curve(s) are of little use because a) The data does not extend to very high frequencies (i.e. it usually stops between 15 and 20 kHz), and b) the data is based on median results. Ideally, I would like real data to confirm the anecdotal evidence that young and/or gifted listeners can hear up to 25kHz (or beyond?). Equal loudness data would be useful too, but the most useful information would be an indication (very very roughly) of the % of listeners of a particular age who can hear a particular frequency at a particular amplitude. Is there anything like this in the published literature? I have looked several times, but everything I find stops at 16kHz! Also, anything other than median results seems very thin on the ground. Thanks in anticipation of any help - any pointers would be very greatfully received! Cheers, David. http://www.David.Robinson.org/ P.S. I can't see the local primary school being too keen to lend out children for a high frequency listening test - is this the reason no one else has studied this?
