Harpies and Silenced Areas

[Millefune]

If a player is captivated by a Harpy's song, and moves through an area with Silence active, or has a Silenced area moved to him, does the Harpy's song effect still affect him and keep him captivated if the Harpy is still singing and not itself Silenced?

I was under the impression that the person had to be hearing the singing in order for him or her to continue being captivated and keep moving toward her.

It's a sonic effect, so silence prevents it. The victim is still affected for one round, as if the harpy had stopped singing.

edit: If he hears the song again within that round (probably because he moved out of the silence towards the harpy on his turn) he is still captivated so the effect continues while the harpy keeps singing. If he ceases being captivated after one round but then is exposed to the song again, he hasn't successfully saved within 24 hours so he must attempt the save again.
