A hypothesis has been put forward regarding the functional purpose of the known ancient Egyptian artifact – the Sabu Disk. According to the proposed hypothesis, similar disks were used in ancient Egypt in “talking” statues as sound sources. The sounds produced resembled human speech – something like indistinct muttering. The Sabu Disk, in the form of a distinctive headdress, was placed on the head of the deity's speaking statue. The disk was secured by means of a bushing fitted over the tenon protruding from the parietal region of the statue’s head. The wind, blowing over this headdress, induced mechanical vibrations in the three tongues – the curved petals of the disk. When combined, the sound vibrations of these tongues (voices) produced beats. The resulting sound was filtered and amplified inside the resonator cavity formed by the disk’s dome and the parietal surface of the statue’s head; after which it was directed down toward the base of the statue in a diverging cone. The article also proposes the most technologically plausible methods for producing such “stone” disks.
