To where does the meaningful aural indication of the steady BLUE light go?

The steady BLUE light serves as a critical communication tool within the aircraft, specifically indicating a situation that requires attention from the cabin crew. When this light is activated, the signal is directed to the FA (Flight Attendant) station, thereby ensuring that the cabin crew is promptly made aware of the condition that necessitates their awareness or action. This aural indication is essential for maintaining safety and proper communication among the flight crew and the cabin crew.

In contrast, while other locations such as the cockpit team or lavatory area may have their own signaling systems, they do not specifically receive the notifications signaled by the steady BLUE light. The cabin crew lounge is also not involved in the direct communication for imminent in-flight situations as indicated by this signaling. Thus, the primary purpose of the steady BLUE light's indication is to effectively reach the FA station to ensure that cabin crew members are informed and can respond appropriately.
