Subject: Re: How to create apparent continuity of a tone without From: Leon van Noorden <leonvannoorden(at)CHELLO.BE> Date: Wed, 11 May 2005 10:43:00 +0200Dear Annekathrin, The excitation of the noise should be bigger than that of the tone, everywhere where there is excitation of the tone. You could decrease the bandwidth of the noise to reduce its loudness, as long as this condition is met.

Dear list, I would like to create the auditory illusion "apparent continuity". The structure of my tone is: 350ms tone (A) - 25 ms burst of a white noise (B) - 275 ms tone (A). A is a 440 Hz pure ton. Does anybody know if there is a possibility to create an apparent continuity of the tone A without increasing the overall amplitude of the white noise about 20 times as that of the tone? Or is it a strict condition to enhance the loudness to create such an auditoy illusion effect? Or is it a strict condition to enhance the loudness if you want creat such an auditory illusion effect? Best, Annekathrin Weise. -- +++ Lassen Sie Ihren Gedanken freien Lauf... z.B. per FreeSMS +++ GMX bietet bis zu 100 FreeSMS/Monat: http://www.gmx.net/de/go/mail
