The best way to communicate to the Flight Deck with a PBE on is to put the interphone to your ________ _______.

• A. Microphone
• B. Receiver
• C. Earpiece
• D. Voice Box

Answer: (D)

When a PBE is worn, the hood can muffle and dull your voice, making it hard for the Flight Deck to hear you. Placing the interphone at your voice box—the throat area where your vocal cords produce sound—lets the microphone pick up your voice more clearly by capturing the natural vocal vibrations directly. This improves intelligibility even with the hood on. The other options relate to listening or are not about where your voice originates, whereas the voice box is the source of the voice you’re transmitting.
