What device attached to the SCBA face piece projects voice?

• A. Voice amplifier
• B. Radio
• C. Bell
• D. Microphone

Answer: (A)

The main idea is that voice projection from the SCBA face piece is handled by a voice amplification unit. This device sits on or integrates with the face piece and takes your spoken words captured by the microphone, boosts their volume, and makes them clear enough to be heard through the radio or by nearby teammates in a noisy environment. The microphone itself only captures sound, not amplify it, and the radio carries the signal but does not by itself project your voice from the face piece. A bell serves no role in voice communication. So the component that directly makes your voice audible and intelligible in SCBA use is the voice amplifier.
