Re: How to create apparent continuity of a tone without increasing the loudness of the white noise about 20 times as that of the tone?

Dear 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.

Objet : How to create apparent continuity of a tone without increasing the
loudness of the white noise about 20 times as that of the tone?

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.
