an auditory illusion

["James W. Beauchamp" <jwb@xxxxxxxxxxxxxxxxxxxxx>]

A physics student at our university just queried me about the following
alleged illusion:

>I am looking for a recording of an acoustic
>illusion which I heard a while ago:  You hear some garbled noise, then
>someone tells you that a message, such as "My name is Al" is in there
>among the noise.  Upon hearing the garble again, the message can be heard
>clearly.

Does anyone know if a recording of this example is available?
