Archaeo-Acoustics

One of our favorite shows, MythBusters, having a scream exploring the myth of "archaeo-acoustics" — i.e., ancient pottery can contain sounds from the past that can be played back and listened to today, just like a record.

Evidently, during the Pompeiian period, while potters worked at their wheel, any extraordinary sound bytes that came within their environment while they were at the wheel, would be recorded on their pot! (They hypothosized this on the X-Files some years ago)

They apply a glass stylus to a grove on the pot as the pot rotates on the wheel, and one hears a ghostly voice. Then they took their recording to a professional to erradicate the eroneous noise and reveal the truth.

What do you think the result was?
