In the video, the man explains that there are many different sounds one can hear during a flight.
The first and most common sound is the two tones that indicate a flight attendant calling another one, or the flight deck calling.
The other sound is only one tone, and this indicates that a passenger is calling a flight attendant.
The sound you never want to hear involves three tones, and this indicates that there is an emergency on board.
