The call system for the captain will have the audio signal of a
- hi tone chime.
- horn.
- two tone chrime.
Explanation from PART66Online
On the flight-crew/cabin call system, a call directed to the captain is annunciated by a single high-tone chime, distinguishing it from other call types. A horn or a two-tone chime is used for different functions, so they would not signal a routine call to the captain.

The audio signals and warning systems can vary between different aircraft models and manufacturers. Each manufacturer may adopt different standards for audio signals based on their design specifications and operational requirements.
