Low frequencies (beyong hearing) in particular can resonate with body parts and organs and affect us in that way. This is a fast track way to many emotions, feelings and even pleasure and pain. It was discovered not so long ago that although people could not hear frequencies above 22kHz which is the maximum CD frequency that some could tell the difference between (say) 15kHz waves with different timbre or different overtones. Some CD manufacturers now add overtones to the high frequencies because that normally produces a more natural sound. This little trick does fool those individuals who could tell the difference before. -- Ray Tomes -- rtomes@kcbbs.gen.nz -- Harmonics Theory -- http://www.kcbbs.gen.nz/users/rtomes/rt-home.htm Received: from ns.ezh.nl [137.174.112.59] by vbv40.ezh.nl with SMTP-OpenVMS via TCP/IP; Fri, 14 Mar 1997 05:28 +0100 Received: by ns.ezh.nl; (5.65v3.2/1.3/10May95) id AA13534; Fri, 14 Mar 1997 05:28:09 +0100 Received: from ella.mills.edu by ns (smtpxd); id XA13531 Received: from by ella.mills.edu via SMTP (940816.SGI.8.6.9/930416.SGI) id UAA08996; Thu, 13 Mar 1997 20:26:19 -0800 Date: Thu, 13 Mar 1997 20:26:19 -0800 Message-Id: <199703132324_MC2-1292-664F@compuserve.com> Errors-To: madole@mills.edu Reply-To: tuning@ella.mills.edu Originator: tuning@eartha.mills.edu Sender: tuning@ella.mills.edu
