[kyriakos]

small correction “phonē” means voice not sound :)

[coldtea]

In ancient and koinē Greek it meant both voice and sound (including the sound of instruments, which carries in modern instrument names like "saxophone" and so on).

They would say "ὀργάνων φωναί", "φωνὴ βροντῆς", "φωνὴ ὑδάτων" and so on for example.
