Subject: Term II: Uniformly exciting From: Bill Woods <wsw(at)MEDI.PHYSIK.UNI-OLDENBURG.DE> Date: Thu, 11 Apr 1996 15:40:43 +0200Dear Colleagues, Well, the 6-hour time difference has made for quite a significant early response from the English-as-native-language European contingent of the list. I've received already 3 responses from folks in England (and one from an early bird in Indiana). I've attached them below. In summary, the term seems to be a direct translation of the German that my colleague here originally used in asking me, "gleichmaessig anregendes Rauschen", or "uniformly exciting noise", and seems traceable to some work by Zwicker and colleagues. Two other related points seem noteworthy. Uniformly exciting noise is similar to pink noise, but the relatively constant auditory filter bandwidth at lower center frequencies makes them not exactly equivalent in the strictest lexicons (something I should have pointed out in my first message). Also, Brian Moore pointed out that one should be careful in where they define the filter input to be, and note the effect of the outer and middle ear transfer characteristics. Thanks for the help. -Bill Woods > From strick(at)sage.cc.purdue.edu Thu Apr 11 15:00:23 1996 > Date: Thu, 11 Apr 1996 07:58:19 -0500 > X-Sender: strick(at)sage.cc.purdue.edu > X-Mailer: Windows Eudora Version 2.0.3 > Mime-Version: 1.0 > Content-Type> : > text/plain> ; > charset="us-ascii"> > To: Bill Woods <wsw(at)medi.physik.uni-oldenburg.de> > From: strick(at)sage.cc.purdue.edu (Beth Strickland) > Subject: Re: Terminology > Content-Length: 64 > > We call it pink noise.
